    Resumo em Inglês:

    ABSTRACT Introduction: Implantable cardiac pacemakers or cardioverter defibrillators are alternatives for the treatment of arrhythmias, however, their use has caused changes in the emotional state of patients. The objective of this study was to compare the measures of anxiety and depression symptoms in individuals according to their sex, type of cardiac device, and diagnosis of Chagas disease. Methods: This is an observational and cross-sectional study conducted with adults with implantable cardiac pacemakers or cardioverter defibrillators. Data was collected using a sociodemographic and clinical questionnaire and the Hospital Anxiety and Depression Scale. We used the Student’s t-test for independent samples and the Chi-squared test, with a significance level of 0.05. Results: Two hundred forty-four patients participated in the study, 168 with cardiac pacemakers and 76 with implantable cardioverter defibrillators; 104 had Chagas cardiomyopathy (85 with cardiac pacemakers and 19 with implantable cardioverter defibrillators). No statistically significant differences were found in measures of anxiety and depression symptoms according to device type (P=0.594 and P=0.071, respectively) and the presence of Chagas etiology (P=0.649 and P=0.354, respectively). Women had higher mean scores for anxiety (P=0.002) and depression symptoms (P<0.001). Conclusion: In the comparison between the groups, according to the type of implanted device and the diagnosis of Chagas disease, no significant differences were found in the measures of anxiety and depression symptoms. Women showed higher means when compared to men, indicating the need to test and implement interventions to minimize these symptoms in this population.

    Resumo em Inglês:

    ABSTRACT Objective: To compare health-related quality of life (HRQoL) of patients primarily treated with a no-touch saphenous vein graft with that of patients who received a conventional graft. Methods: The study included all individuals treated with a percutaneous coronary intervention (PCI) on a saphenous vein graft (SVG) between January 2006 and June 2020. The RAND-36 health survey was used to assess HRQoL. The Mann-Whitney U test was used to test differences in HRQoL between the two groups. Effect size was estimated via Cohen’s d. The average treatment effect between the groups was tested by propensity score matching (PSM). Results: Of the 346 patients treated with a PCI in a stenosed or occluded SVG, 165 responded to RAND-36 (no-touch: n=48; conventional: n=117). Patients with a no-touch graft reported better mean values on seven of the eight health survey domains. Statistically significant differences were observed for four of the domains, all in favour of the no-touch group. The effect size estimates indicated a small difference for five domains, with the highest values (>0.40) seen for the general health and energy/fatigue domains. PSM confirmed a statistically significant difference for the physical functioning and general health domains. Conclusion: At a mean follow-up of 5.4 years, patients who received a PCI in no-touch vein grafts showed significantly better HRQoL than those who received a PCI in conventional vein grafts.
  • Adventitial Collagen Cross-Linking by Glutaraldehyde Reinforcing Human Saphenous Vein - Implication for Coronary Artery Bypass Grafting Original Article

    Liu, Changcheng; Chen, Duanduan; Li, Zhenfeng; Xu, Huanming; Gu, Chengxiong

    Resumo em Inglês:

    ABSTRACT Introduction: A weak venous wall is one of the major reasons contributing to vein graft failure after coronary artery bypass grafting (CABG). We investigated whether adventitial collagen cross-linking by glutaraldehyde reinforces venous wall, preserving the endothelium of veins during high-pressure distention. Methods: Human saphenous veins (SVs) were collected from 40 patients undergoing CABG, and adventitia cross-linking was performed with 0.3% glutaraldehyde for five minutes. The cross-linked SVs were accessed by biodegradation assay, immunofluorescent staining, and tensile test. Native SVs and cross-linked SVs from another 20 patients received the 200 mmHg pressure distention for two minutes. Pressure-induced injury of SVs were accessed by immunohistochemistry and electron microscopy. Results: Time to digestion was 97±13 minutes for native SVs and 720±0 minutes for cross-linked SVs (P<0.05). After adventitial cross-linking, the collagen I fibres of the vein remarkably presented with compact and nonporous arrangement. In the high-stretch region (stretch ratio 1.4-1.8), the Young’s elastic modulus of stress-stretch ratio curve in cross-linked SVs was larger than that in native SVs (13.88 vs. 5.83, P<0.05). The cross-linked SVs had a lower extent of endothelial denudation without fibre fracture during high-pressure distension than native SVs. Comparing with the non-cross-linked SVs, the percentage of endothelial nitric oxide synthase staining length on the endothelium of cross-linked SVs was significantly preserved after high-pressure distension (85.2% vs. 64.7%, P<0.05). Conclusion: Adventitial collagen cross-linking by glutaraldehyde reinforced venous wall by increasing stiffness and decreasing extensibility of SVs and mitigated the endothelial damage under high-pressure distension.
  • MicroRNA-124a Protects the Myocardium Against Ischemia Reperfusion Injury Through Regulation of the Notch Signaling Pathway Original Article

    Resumo em Inglês:

    Abstract Introduction: This study’s objective is to investigate the effect of downregulation of micro ribonucleic acid (miR)-124a on myocardial injury after ischemia reperfusion (I/R) in rats. Methods: Sprague Dawley (SD) rats (n=20) were divided into four groups - sham, I/R, I/R+miR-124a antagomir (I/R+ant-miR-124a), and I/R+ant-normal control (NC). The pathomorphological and infarct size variance of injured myocardial tissues with IR were conducted with hematoxylin (HE) and triphenyltetrazolium chloride (TTC) staining. The expression levels of miR-124a, BAX, nuclear factor kappa B (NF-KB), Notch1, and Hes1 were examined by quantitative real-time polymerase chain reaction or Western blot in myocardium. The inflammatory cytokines interleukin (IL)-6, IL-1β, and tumor necrosis factor alpha (TNF-α) were detected by the enzyme-linked immunosorbent assay, as well as the activity of lactate dehydrogenase (LDH) and creatine kinase (CK) in serum by colorimetry. Results: The expression of miR-124a was increased in the I/R group. Compared with I/R and I/R+ant-NC groups, after downregulating miR-124a, the expression of IL-6, IL-1β, TNF-α, BAX, NF-KB, LDH, and CK were decreased, but the expression of Notch1 and Hes1 were increased. In HE staining, myocardial tissue edema, red blood cell exudation, and myocardial fiber arrangement disorder were accompanied by inflammatory cell infiltration and local necrosis in the I/R group. However, the pathological injury of myocardial tissue was alleviated after downregulating miR-124a. Additionally, TTC results showed that the myocardial infarction area was decreased in the I/R+ant-miR-124a group. Conclusion: Downregulation of miR-124a expression through Notch pathway can significantly reduce myocardial damage after 24 hours of I/R in SD rats. Therefore, miR-124a may become a potential therapeutic target for I/R injury.

    Rodrigues Junior, Luiz Fernando; Moreira, Beatriz Robert; Duque, Alice Pereira; Oliveira, Juliana Rega de; Figueiredo, Pedro Henrique Scheidt; Oliveira, Cláudia Rosa de; Colafranceschi, Alexandre Siciliano; Mediano, Mauro Felippe Felix; Guimarães, Tereza Cristina Felippe

    Resumo em Inglês:

    ABSTRACT Introduction: Heart rate control by the autonomic nervous system (ANS) is impaired in heart transplant (HT) recipients, leading to increased resting heart rate, metabolic demand, and fatigue, which can impair their quality of life (QoL). In this study, we hypothesized the association of hemodynamics and autonomic function as predictors of QoL in HT recipients. Methods: This is a cross-sectional study conducted with HT recipients aged ≥ 18 years at ambulatorial accompaniment. Blood pressure was used for hemodynamics assessment, and heart rate variability (HRV) was used for ANS assessment. QoL was assessed by the 36-item Short Form Health Survey. The significance level was set as P≤0.05. Results: Twenty-two volunteers were included in the study. Systolic blood pressure (SBP) and double product (DP) were significantly negatively associated with the physical functioning domain of QoL. DP, the number of consecutive normal RR interval differences > 50 ms (NN50), and the percentage of normal RR intervals that differed by > 50 ms from the adjacent interval (PNN50) exhibited negative association with the physical role domain. NN50 and PNN50 were significantly associated with bodily pain, social functioning, and emotional role domains. SBP was negatively associated with the vitality domain. Considering general and mental health domains, no variable demonstrated significant association. DP, NN50, and PNN50 were negatively associated with the total score of QoL. Conclusion: This study demonstrated DP and HRV as predictors of QoL in HT recipients. These innovative results can become a relevant therapeutic target for improving QoL in HT recipients prior to its deterioration.
  • Surgical Approach and Management Strategies in a Pediatric Cardiovascular Surgery Clinic During the COVID-19 Outbreak Original Article

    Arslanoğlu, Ergin; Işık, Mehmet Emirhan; Kara, Kenan Abdurrahman; Çine, Nihat; Tunçer, Eylem; Ceyran, Hakan

    Resumo em Inglês:

    ABSTRACT Introduction: The coronavirus disease 2019 (COVID-19) pandemic has required changes in the management of pediatric cardiac surgery. We would like to share the patient treatment and surgical management strategies employed in our Pediatric Cardiovascular Surgery Clinic during the COVID-19 pandemic. Methods: A total of 112 patients were followed up in our clinic between 11.03.2020 and 02.07.2020. Their mean age was 1,118 (4-5,740) days. Management and treatment were performed by our pediatric heart team (pediatric cardiac anesthetists, general pediatricians, pediatric cardiologists, pediatric cardiac surgeons, and an infectious diseases specialist). We prepared new protocols and a surveillance system specific to the pandemic to prevent in-hospital transmission and reduce postoperative mortality and morbidity; our operations were performed according to these protocols. All decisions pertaining to the operation timing and treatment strategy of our COVID-19-positive patients were made by the same team. Results: During the study period, a total of 112 patients, 69 boys and 43 girls, were hospitalized in our clinic. A total of 333 COVID-19 real-time polymerase chain reaction tests were performed on patients and accompanying persons; positive results were found in three patients and two accompanying individuals. Conclusion: By employing new protocols and a surveillance system throughout the healthcare system, we think that early diagnosis and treatment of the pediatric congenital heart disease population, which is susceptible to infections, can continue unperturbed. This and similar approaches can increase postoperative success and prevent transmission in the pediatric population - which are frequently COVID-19 asymptomatic.

    Yin, Sijuan; Ou, Yangyi; Ting, E

    Resumo em Inglês:

    ABSTRACT Introduction: The objective of this study is to explore the impacts of Omaha System-based continuing care on medication compliance, quality of life (QOL), and prognosis of coronary heart disease (CHD) patients after percutaneous coronary intervention (PCI). Methods: A total of 100 CHD patients who were hospitalized and received PCI were selected and divided into the control group and the observation group, 50 patients per group, according to a random number table method. The control group was given routine care, while the observation group was applied Omaha System-based continuing care on the basis of the control group. Results: Follow-up demonstrated that the Morisky-Green score of the observation group was significantly higher than that of the control group (P<0.001), indicating that the medication compliance of the observation group was significantly better than that of the control group (P<0.001). The short form-36 (SF-36) scores were notably higher after nursing compared with on admission; SF-36 scores of the observation group were significantly increased than those of the control group (P<0.001). The incidence of major adverse cardiac event (MACE) in the observation group was significantly lower than in the control group (P<0.001). The nursing satisfaction of the observation group was considerably higher than that of the control group (P<0.01). Conclusion: Omaha System-based continuing care could improve the medication compliance and QOL, reduce the incidence of MACE, and benefit the prognosis of CHD patients after PCI.
  • Oxidative Stress and Changes of Important Metabolic Gene Expressions as a Potential Biomarker in the Diagnosis of Atherosclerosis in Leukocytes Original Article

    Işık, Mesut; Tunç, Abdullah; Beydemir, Şükrü

    Resumo em Inglês:

    ABSTRACT Introduction: Presenilin 1 (PSEN1), catalase (CAT), glutathione-S-transferase (GST) and paraoxonase 1 (PON1) play a vital role in prediction, diagnosis and therapy of metabolic disorders. Methods: Metabolic enzyme activities and lipid peroxidation in serum of cerebrovascular diseases (CVD) and coronary artery diseases were measured by spectrophotometric methods. mRNA was isolated from leukocytes of the patient group and healthy adult patients. Quantitative gene expression of PSEN1, CAT and GST mRNA was identified by quantitative real-time polymerase chain reaction (qPCR). Results: The PSEN1, CAT and GST expression in patients showed significant differences compared to the control group. PSEN1 expression in leukocytes was significantly about twice as high as that of the control group in patients with CVD. The GST, CAT and PON1 activity showed significant differences in patient groups compared to the control group. Conclusion: The mRNA expression levels can be used as a potential biomarker in the diagnosis of atherosclerosis that occurs as a result of the metabolic disorder. In atherosclerotic patients, antioxidant status is independently related to an increased risk of cardiovascular events. Antioxidant activities and mRNA expressions may have predictive value, as well as available risk factors.

    Değirmencioğlu, Aleks; Karakuş, Gültekin; Zencirci, Ertuğrul; Güllü, Ahmet Ümit; Şenay, Şahin

    Resumo em Inglês:

    Abstract Introduction: There are several approaches for pericardiocentesis. However, there is no definite suggestion about puncture location after cardiac surgery. The purpose of this study is to examine whether there is any difference regarding puncture location during pericardiocentesis in postoperative cardiac tamponade comparing to nonsurgical cardiac tamponade. Methods: We retrospectively analyzed patients who had undergone pericardiocentesis from August 2011 to December 2019. Patients were examined in two groups, nonsurgical and postsurgical, based on the etiology of pericardial tamponade. Clinical profiles, echocardiographic findings, and procedural outcomes were identified and compared. Results: Sixty-eight pericardiocenteses were performed in this period. The etiology of pericardial effusion was cardiac surgery in 27 cases and nonsurgical medical conditions in 41 cases. Baseline demographic variables were similar between the surgical and nonsurgical groups. Loculated effusion was more common in the postsurgical group (48.1% vs. 4.9%, P<0.001). Maximal fluid locations were different between the groups; right ventricular location was more common in the nonsurgical group (36.6% vs. 11.1%, P=0.02), while lateral location was more common in the postsurgical group (12.2% vs. 40.7%, P=0.007). Apical drainage was more frequently performed in the postsurgical group compared to the nonsurgical group (77.8% vs. 53.7%, P=0.044). Conclusion: Apical approach as a puncture location can be used more frequently than subxiphoid approach for effusions occurred after cardiac surgery compared to nonsurgical effusions. Procedural success is prominent in this group and can be the first choice of treatment.

    Güven, Cengiz; Kafadar, Hüseyin

    Resumo em Inglês:

    Abstract Introduction: The goal of this study is to investigate the association between diagnosis and severity of coronary artery disease (CAD) and Asprosin level. Methods: Patients diagnosed with CAD who underwent conventional coronary angiography for the first time were included in the present study. The patients were divided into four groups, each consisting of 20 individuals, as medical group, single coronary lesion group, double coronary lesion group, and multiple coronary lesions group. Serum Asprosin values and Gensini scores of the groups were compared in terms of compliance. Results: In this study, Asprosin values were found to be significantly higher in the multiple coronary lesions group than in the medical, single coronary, and double coronary lesion groups (P<0.05). In the double coronary lesion group, Asprosin values were significantly higher (P<0.05) than the in the medical and single coronary lesion groups. It was also found that Asprosin values did not differ at significant levels in the medical and single coronary lesion groups (P>0.05). It was determined that the increases in Asprosin values and Gensini scores were compatible with each other. Conclusion: The present study showed that the increases in serum Asprosin levels, along with the increases in the number of coronary arteries with critical stenosis, might be a marker in diagnosing and determining the severity of CAD.
  • Endothelial Progenitor Cells and NADPH Oxidase Enzyme Activity in the Development of an Aortic Aneurysm Original Article

    Bingol, Bilge; Elcik, Deniz; Kutuk, Sinan; Özsoy, Sevil; Kelesoglu, Saban; Tuncay, Aydin; Cetinkaya, Zeki; Sulaiman, Joma; Inanc, Mehmet Tugrul; Kalay, Nihat; Koker, Mustafa Yavuz

    Resumo em Inglês:

    Abstract Introduction: Endothelial progenitor cells (EPCs) and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase enzyme activity may affect the vessel wall and have a role in development of aortic aneurysms. EPCs originate from hematopoietic stem cells and can be enumerated from peripheral blood samples by flow cytometry. In this study, we aimed to evaluate the relation of EPC number and NADPH oxidase enzyme activity in the development of thoracic aortic aneurysm (TAA). Methods: Patients with TAA (n=30) and healthy individuals without TAA (control, n=10) were included in our study. Characterization and enumeration of EPC from peripheral blood samples were performed by flow cytometry with panels including markers of EPCs (CD34/CD133/CD309/CD146/CD144). Additionally, NADPH oxidase enzyme activity (capacity) was also measured by the dihydrorhodamine 123 (DHR 123) test. Results: The enumeration of EPC with CD34+/CD146+ marker showed that the number of mean EPC/106 cells was increased in the patient group (41.5/106 cells), but not in the control group (20.50/105 cells) (P<0.01). Additionally, patients with TAA presented significantly lower NADPH oxidase activity by DHR assay than healthy controls (mean stimulation index: 60.40± 7.86 and 75.10±5.21, respectively) (P<0.01). Conclusion: Our results showed that the number of EPCs is significantly higher in aortic aneurysm patients and may have a role in disease progression. The crosstalk between NADPH oxidase enzyme capacity and EPC number may be useful as a parameter to explain the clinical progression of TAA.
  • Intracardiac Repair in Late Adolescent and Adult Tetralogy of Fallot — Early and Midterm Results from a Tertiary Care Centre Original Article

    Bhushan, Rahul; Chugh, Vaibhav; Loona, Manpal; Bandey, Javed; Jhajhria, Narender Singh; Grover, Vijay; Gupta, Vijay Kumar

    Resumo em Inglês:

    Abstract Introduction: In developing countries like India, it is common for late presentation of Tetralogy of Fallot (TOF) patients to a hospital as compared to that of developed countries. The objective of this study is to analyze the surgical outcome of TOF patients with age > 15 years. Methods: This is a retrospective descriptive study of the surgical outcomes of 45 adult patients undergoing correction for TOF. Epidemiology, symptomology, and preoperative evaluation were performed. Results: Most of the patients were male (33 [73%]). The median age was 21 years. A total of 42 (93.33%) patients had subaortic ventricular septal defect (VSD), while three (6.6%) patients presented with doubly committed VSD. The most common type of right ventricular outflow tract (RVOT) obstruction was combined infundibular and valvular types, accounting for 34 cases (75.5%). Six patients had infundibular RVOT obstruction, while three patients (6.6%) had predominantly valvular pulmonary stenosis. We performed trans-right atrial repair in 33 patients. Right atrium-pulmonary artery approach was used in five patients (11.1%). The most common postoperative complication was right bundle branch block, seen in 14 patients, with a mortality rate of 2% in the early postoperative period. We achieved excellent early and midterm survival results and significant improvement in functions and disease-free quality of life. Conclusion: Intracardiac repair in adult TOF can be performed with low mortality, less residual RVOT obstruction, and need for revision of RVOT far less frequent by using the Jhajhria Infundibular Resection Adequacy Assessment technique (JIRAAT) to assess for adequacy of infundibular resection.
  • The Importance of HbA1c and Left Ventricular Ejection Fraction in Predicting the Development of Postoperative Mortality and Complications in Coronary Artery Bypass Graft Surgery Original Article

    Özmen, Rifat; Tunçay, Aydın; Yılmaz, Halis; Sarı, Gülden; Taşdemir, Haluk Kutay

    Resumo em Inglês:

    Abstract Introduction: In this study, we aimed to investigate the relationship between postoperative mortality, morbidity, hospital stay and development of postoperative complications with the glycosylated hemoglobin (HbA1c) level and low left ventricular ejection fraction (LVEF) in diabetic and non-diabetic patients who underwent elective coronary artery bypass (CABG) surgery. Methods: The medical records of patients who underwent CABG at our clinic between January 2015 and December 2019 were retrospectively analyzed. All patients were divided into two groups according to their diabetes mellitus (DM) diagnosis. Diabetic patients were also divided into two groups according to their HbA1c levels. The HbA1c threshold value was 7%. All patients were divided into two groups in terms of LVEF. The LVEF threshold value was 40%. Results: We analyzed 393 patients, of which 304 (77.4%) were male and 177 (45.04%) patients were diabetic. For lower LVEF and HbA1c values, we found no relationship between postoperative mortality, prolonged intensive care unit (ICU) stay and development of postoperative complications. Deep surgical site infection (DSSI) was found to be more common in diabetic patients who had a higher HbA1c value. Length of hospital stay was longer in diabetic patients with HbA1c levels <7%. Conclusion: No statistically significant relationship was found between LVEF and HbA1c levels and postoperative mortality, prolonged ICU stay and postoperative complications.
  • Long Noncoding RNA AF131217.1 Regulated Coronary Slow Flow-Induced Inflammation Affecting Coronary Slow Flow via KLF4 Original Article

    Jiang, Haibing; Ge, Zhengrong; Zhang, Lijing; Yang, Yi; Zhai, Xueqin; Chen, Zhanxi; Wei, Qing

    Resumo em Inglês:

    Abstract Introduction: This study investigated the correlation between the levels of long noncoding ribonucleic acids (lncRNAs) AF131217.1 and coronary slow flow (CSF). Methods: A total of 22 patients in the high-sensitivity C-reactive protein (hsCRP) group diagnosed with CSF from January 2018 to December 2018 were enrolled in this study. Coronary flow velocity was determined using the thrombolysis in myocardial infarction frame count (TFC) method. Results: LncRNA AF131217.1 expression in the CSF model was activated. Mean TFC was positively correlated with lncRNA AF131217.1 levels and hsCRP levels. LncRNA AF131217.1 induced inflammation factor levels in the in vitro model. Micro ribonucleic acid (miR)-128-3p is a target spot of lncRNA AF131217.1 on the inflammation in vitro model via Kruppel-like factor (KLF) 4. MiR-128-3p reduced inflammation factor levels (tumor necrosis factor alpha, interleukin [IL]-6, IL-1β, and IL-18). Conclusion: Thus, lncRNA AF131217.1 promoted inflammation in the regulated CSF via KLF4 by miR-128-3p.
  • Congenitally Corrected Transposition of the Great Arteries in the Adult Review Article

    Amaral, Fernando; Valente, Anne Marie; Manso, Paulo Henrique; Gali, Luiz Gustavo; Braggion-Santos, Maria Fernanda; Rocha, Julia Mignot; Vicente, Walter Vilella de Andrade; Schmidt, André

    Resumo em Inglês:

    ABSTRACT Introduction: Congenitally corrected transposition of the great arteries (CCTGA) is a rare anomaly. Current data available regarding adult cases is derived from small series, information simultaneously presented in pediatric publications, and one classical multicenter study. This review, not aimed to exhaust the subject, has the purpose to examine the literature addressing presentation, diagnostic methodology, and management of afflicted adult patients. Methods: A comprehensive search was undertaken in three major databases (PubMed, Cochrane, SciELO), using the keywords “congenitally corrected transposition of the great arteries” and “adults”. Relevant articles in English, Spanish, and Portuguese were extracted and critically appraised in this review. Steps for study selection were: (1) identification of titles of records through databases searching, (2) removal of duplicates, (3) screening and selection of abstracts, (4) final inclusion in the study. Results: Four hundred sixty-five publications on CCTGA in adult patients were retrieved, and 166 were excluded; 299 studies were used for this review including 76 full-text articles, 70 studies related to general aspects of the subject, and, due to the small number of publications, 153 case reports. Sixty-one articles referring to combined experiences in pediatric and adult patients and judged to be relevant, but retrieved from another sources, were also included. Conclusion: Albeit clinical presentation and diagnostic criteria have been well stablished, there seems to be room for discussion related to clinical and surgical management of CCTGA in adults. Considering the rarity of the disease, well designed multicenter studies may provide answers.
  • Redo Coronary Artery Bypass Grafting in the era of Advanced PCI Review Article

    Kusu-Orkar, Ter-Er; Masharani, Kellan; Harky, Amer; Muir, Andrew D

    Resumo em Inglês:

    Abstract Objective: To review the evidence behind the role and relevance of redo coronary artery bypass grafting (CABG) in the current practice of percutaneous coronary intervention (PCI). Methods: A comprehensive electronic literature search was performed to identify articles that discuss the practice of PCI and redo CABG in patients that require coronary revascularization. All relevant studies are summarized in narrative manner to reflect current indications and preference. Results: The advancement in utilization of PCI has reduced the rate of redo CABG in patients with previous CABG that requires revascularization of an already treated coronary disease or a new onset of coronary artery stenosis. Redo CABG is associated with satisfactory perioperative outcomes but higher mortality at immediate postoperative period when compared to PCI. Conclusion: Redo CABG patients are less likely to develop comorbidities associated with revascularisation, but the operative mortality is higher and long-term survival rates are similar in comparison to PCI. There is a need for further research into the role of redo CABG in the current advanced practice of PCI.
  • Meta-Analysis of Pulmonary Artery Denervation for Treatment of Pulmonary Hypertension Review Article

    Zuo, Wanyun; Liu, Na; Xiao, Yunbin; Xie, Yonghui; Liu, Qiming

    Resumo em Inglês:

    ABSTRACT Introduction: Pulmonary artery denervation (PADN) can reduce the sympathetic nervous system (SNS) activity, reduce pulmonary artery pressure (PAP), and improve the quality of life in patients with pulmonary hypertension (PH). We conducted a systematic meta-analysis of the effectiveness of PADN in the treatment of PH patients. Methods: This is a comprehensive literature search including all public clinical trials investigating the effects of PADN on PH. Outcomes were mean pulmonary artery pressure (mPAP), pulmonary vascular resistance (PVR), cardiac output (CO), right ventricular (RV) Tei index, 6-minute walk distance (6MWD), and New York Heart Association (NYHA) cardiac function grading. Results: A total of eight clinical studies with 213 PH patients who underwent PADN were included. Meta-analysis showed that after PADN, mPAP (mean difference [MD] -12.51, 95% confidence interval [CI] -17.74 to -7.27, P<0.00001) (mmHg) and PVR (MD -5.17, 95% CI -7.70 to -2.65, P<0.0001) (Wood unit) decreased significantly, CO (MD 0.59, 95% CI 0.32 to 0.86, P<0.0001) (L/min) and 6MWD (MD 107.75, 95% CI 65.64 to 149.86, P<0.00001) (meter) increased significantly, and RV Tei index (MD -0.05, 95% CI -0.28 to 0.17, P=0.63) did not change significantly. Also after PADN, the proportion of NYHA cardiac function grading (risk ratio 0.23, 95% CI 0.14 to 0.37, P<0.00001) III and IV decreased significantly. Conclusion: This meta-analysis supports PADN as a potential new treatment for PH. Further high-quality randomized controlled studies are needed.
  • A New Dawn for Brazilian Pediatric Cardiac Surgery Is on the Way - Issues Around and Outside the Operating Room Special Article

    Caneo, Luiz Fernando; Miana, Leonardo Augusto; Garros, Daniel; Neirotti, Rodolfo

    Resumo em Inglês:

    ABSTRACT In some developing countries, congenital heart disease still stands out among the leading causes of death in the first year of life. Therefore, there is a great need to develop programs designed to improve outcomes in the diagnosis and surgical treatment of congenital heart disease in these nations, where children have always been and still are severely underserved. The Brazilian Public Health Care System demands universal access to treatment as a constitutional right. Therefore, an underfunded Pediatric Cardiac Surgery program is unacceptable since it will cost lives and increase the infant mortality rate. Additionally, poor funding decreases providers’ interest, impedes technological advances and multidisciplinary engagement, and reduces access to comprehensive care. Unfortunately, in most developing countries, Pediatric Cardiac Surgery progress is still the result of isolated personal efforts, dedication, and individual resilience. This article aims to present the current state of Brazilian pediatric cardiac surgery and discuss the structural and human limitations in developing a quality care system for children with congenital heart disease. Considering such constraints, quality improvement programs via International collaboration with centers of excellence, based on proper data collection and outcomes analysis, have been introduced in the country. Such initiatives should bring a new dawn to Brazilian Pediatric Cardiac Surgery.

  • Surgical Management of The Endomyocardial Fibrosis of Right Ventricle Mimicking Tumor with Recurrent Pulmonary Embolism How I Do It

    Bzikha, Reda; Queron, Sébastien

    Resumo em Inglês:

    ABSTRACT Endomyocardial fibrosis is a neglected tropical disease that leads to restrictive cardiomyopathy. Its etiopathogenis is unclear and involves the progression of 3 stages of the disease. Compared with echocardiography, cardiac magnetic resonance imaging shows better apical visualization of obliteration and thrombus and provides an early diagnosis. However, there is no specific drug therapy, although surgery can increase survival. Therefore, surgical resection of the fibrous and thickened endocardium is recommended for symptomatic patients. The risk of mortality increases as the ratio of endocardial fibrous tissue per body surface rises. The aim of this manuscript is to describe the surgical management of the right-sided endomyocardial fibrosis mimicking tumor with recurrent pulmonary embolism.
  • COVID-19 Positive Cohort Undergoing Cardiac Surgery: A Possible Un(3H)oly Trinity of Hypoxia-Hemolysis-Hyperinflammation Brief Communication

    Magoon, Rohan; Kashav, Ramesh; Jose, Jes; Walian, Ashish; Dey, Souvik

    Resumo em Inglês:

    Abstract While the fraternity continues to ponder on the mechanisms by which coronavirus disease (COVID-19) positivity affects the outcome of cardiac surgical subset, we put forth a 3H (Hypoxia-Hemolysis-Hyperinflammation) trilogy aimed at elucidating the liaison between cardiopulmonary bypass (commonly employed for cardiac surgical conduct) and COVID-19 infection. A sound comprehension of the same can doubtlessly assist the perioperative team in staging a well-directed pathophysiology-driven management approach.

  • Management of Iatrogenic Aortic Dissections During Percutaneous Right Coronary Artery Interventions Case Report

    Gennari, Marco; Mastroiacovo, Giorgio; Polvani, Gianluca; Fabbiocchi, Franco; Agrifoglio, Marco

    Resumo em Inglês:

    ABSTRACT Iatrogenic acute aortic dissections during percutaneous coronary interventions are an extremely rare but potentially life-threatening complication, occurring in less than 0.02% of transcatheter procedures. We report three patients with different characteristics suffering from iatrogenic aortic dissection during percutaneous coronary intervention successfully treated with an emergency open-heart surgery. A conservative strategy should be pursuit only in small, localized lesions.
  • The Rarity of Penetrating Ulcer with Intramural Hematoma of the Ascending Aorta Case Report

    Patino, Joshua; Roughneen, Patrick T.

    Resumo em Inglês:

    ABSTRACT We report a case of a 58-year-old man with multiple symptomatic penetrating atherosclerotic ulcers and concomitant intramural hematoma of the ascending aorta. The patient was successfully treated using a 24-mm Gelweave graft in the ascending aorta. He was discharged four days post operation and remains asymptomatic 14 months postoperatively. This case uniquely illustrates the rare entity of penetrating atherosclerotic ulcer with intramural hematoma, which presents in only 0.28% of all acute aortic syndrome cases.
  • Multiple Anterior Mitral Valve Perforation After Deep Transfemoral Aortic Valve Implantation Case Report

    Fotbolcu, Hakan; Özdemir, Ramazan

    Resumo em Inglês:

    Abstract Transcatheter aortic valve implantation (TAVI) is an alternative for high-risk aortic valve replacement. There are limited data related to the late complications of TAVI. Deep aortic prosthetic valve implantation can cause direct erosive perforation of anterior mitral leaflet or erosive endothelial lesion which predisposes the tissue to infective endocarditis. Our report emphasizes anterior mitral leaflet perforation after TAVI, which may be seen especially in patients exposed to sepsis.
  • Giant Left Anterior Descending Coronary Artery Aneurysm in a Patient with Behçet’s Disease Case Report

    Meric, Mert; Oztas, Didem Melis; Ugurlucan, Murat; Tireli, Emin; Dayioglu, Enver

    Resumo em Inglês:

    ABSTRACT Coronary artery involvement is quite rare in the course of Behçet’s disease. Complications secondary to coronary artery aneurysms, including rupture, dissection, and myocardial ischemia, may be fatal. In young patients without cardiovascular risk factors, systemic inflammatory vasculitis syndromes should be investigated in case of acute coronary syndrome secondary to dilated coronary arteries. In this report, we present our management strategy in a 31-year-old male patient with Bechet’s disease.
