Resumen: A través de los siglos hemos descubierto la importancia de mantener permeable y segura la vía aérea. Desde Hipócrates en la antigua Grecia, hasta el siglo XX en oriente y occidente, se ha continuado con el desarrollo de herramientas que faciliten esta cotidiana tarea por lo que, con esta revisión sistemática, se establecieron como objetivos exponer el origen y los antecedentes del tubo endotraqueal, cánula orofaríngea y laringoscopio, así como discutir su utilidad en la práctica anestésica-quirúrgica, a través del tiempo hasta hoy en día.

Abstract: Over the centuries, we have discovered the importance of preserving a safe permeable airway. From Hippocrates in ancient Greece to the 20th century in the East and West, the development of multiple tools that enable this task continues through time, which is why with this systematic review we aim to uncover the origin and historical background of the endotracheal tube, the oropharyngeal cannula and the laryngoscope, discussing their effectiveness in the anesthetic-surgical practice over years to the present day.

ABSTRACT Background: Information is needed on the safety and efficacy of direct discharge from the emergency department (ED) of patients with COVID-19 pneumonia. Objectives: The objectives of the study were to study the variables associated with discharge from the ED in patients presenting with COVID-19 pneumonia, and study ED revisits related to COVID-19 at 30 days (EDR30d). Methods: Multicenter study of the SIESTA cohort including 1198 randomly selected COVID patients in 61 EDs of Spanish medical centers from March 1, 2020, to April 30, 2020. We collected baseline and related characteristics of the acute episode and calculated the adjusted odds ratios (aOR) for ED discharge. In addition, we analyzed the variables related to EDR30d in discharged patients. Results: We analyzed 859 patients presenting with COVID-19 pneumonia, 84 (9.8%) of whom were discharged from the ED. The variables independently associated with discharge were being a woman (aOR 1.890; 95%CI 1.176-3.037), age < 60 years (aOR 2.324; 95%CI 1.353-3.990), and lymphocyte count > 1200/mm3 (aOR 4.667; 95%CI 1.045-20.839). The EDR30d of the ED discharged group was 40.0%, being lower in women (aOR 0.368; 95%CI 0.142-0.953). A total of 130 hospitalized patients died (16.8%) as did two in the group discharged from the ED (2.4%) (OR 0.121; 95%CI 0.029-0.498). Conclusion: Discharge from the ED in patients with COVID-19 pneumonia was infrequent and was associated with few variables of the episode. The EDR30d was high, albeit with a low mortality.

Abstract The theoretical evolution of Pedagogy, marked by the accelerated development of Information and Communication Technologies (ICT), has enhanced the potential of mass media for teaching and has contributed to legitimize the existence of formal and informal learning forms, aspects that have allowed to determine educational communication as the object of study of Pedagogy and Communication. The objective of this article is to delve into the theory on the relationship between communication and education. It is concluded that the communication process in the socio-pedagogical context reflects the indisputable link between communication and education as well as the use of mass media and digital technologies in training processes.

Resumen La evolución teórica de la Pedagogía, marcada por el acelerado desarrollo de las Tecnologías de la Información y la Comunicación (TIC), ha realzado las potencialidades de los medios de comunicación masiva para la enseñanza y ha contribuido a legitimar la existencia de formas de aprendizaje no formales e informales, aspectos que han determinado que la comunicación educativa haya pasado a ser objeto de estudio de la Pedagogía y la Comunicación. El objetivo de este artículo profundizar en la teoría sobre el vínculo entre comunicación y educación. Se concluye que el proceso de comunicación dentro del contexto pedagógico y social, refleja el vínculo indiscutible entre comunicación y educación, la utilización de medios masivos de comunicación y tecnologías digitales en procesos formativos.

RESUMO Algumas doenças respiratórias crônicas podem evoluir com hipoxemia e, nessas situações, a oxigenoterapia domiciliar prolongada (ODP) está indicada como opção terapêutica com o objetivo principal de melhorar a qualidade e a expectativa de vida desses pacientes. O oxigênio domiciliar é usado há mais de 70 anos, e a ODP tem como base dois estudos da década de oitenta que demonstraram que o uso de oxigênio melhora a sobrevida de pacientes com DPOC. Existem evidências de que a ODP tem outros efeitos benéficos como melhora da função cognitiva e da capacidade de exercício e redução de hospitalizações. A ODP está indicada para outras doenças respiratórias que cursam com hipoxemia, segundo os mesmos critérios estabelecidos para a DPOC. Tem sido observado aumento no uso da ODP provavelmente pela maior expectativa de vida, maior prevalência de doenças respiratórias crônicas e maior disponibilidade de ODP no sistema de saúde. O primeiro consenso sobre ODP da Sociedade Brasileira de Pneumologia e Tisiologia foi publicado em 2000; após 22 anos, apresentamos esta versão atualizada. Este documento é uma revisão não sistemática da literatura, realizada por pneumologistas que avaliaram evidências científicas e diretrizes internacionais sobre ODP nas diversas doenças que cursam com hipoxemia e em situações específicas (exercício, sono e viagens aéreas). Estas recomendações, tendo em vista a prática clínica, oferecem diversos quadros com informações sobre indicações, fontes de oxigênio, acessórios e estratégias para melhor eficiência, efetividade e uso seguro da ODP, assim como um modelo para sua prescrição.

ABSTRACT Some chronic respiratory diseases can cause hypoxemia and, in such cases, long-term home oxygen therapy (LTOT) is indicated as a treatment option primarily to improve patient quality of life and life expectancy. Home oxygen has been used for more than 70 years, and support for LTOT is based on two studies from the 1980s that demonstrated that oxygen use improves survival in patients with COPD. There is evidence that LTOT has other beneficial effects such as improved cognitive function, improved exercise capacity, and reduced hospitalizations. LTOT is indicated in other respiratory diseases that cause hypoxemia, on the basis of the same criteria as those used for COPD. There has been an increase in the use of LTOT, probably because of increased life expectancy and a higher prevalence of chronic respiratory diseases, as well as greater availability of LTOT in the health care system. The first Brazilian Thoracic Association consensus statement on LTOT was published in 2000. Twenty-two years later, we present this updated version. This document is a nonsystematic review of the literature, conducted by pulmonologists who evaluated scientific evidence and international guidelines on LTOT in the various diseases that cause hypoxemia and in specific situations (i.e., exercise, sleep, and air travel). These recommendations, produced with a view to clinical practice, contain several charts with information on indications for LTOT, oxygen sources, accessories, strategies for improved efficiency and effectiveness, and recommendations for the safe use of LTOT, as well as a LTOT prescribing model.

ABSTRACT Introduction: acute chest pain is a painful sensation perceptible between the diaphragm and the base of the neck. It is one of the most frequent causes of medical consultation in Cuba. It shows a similar behavior in the province of Matanzas. Objective: to characterize the clinical profile of the patients with acute thoracic pain in the Emergency Intensive Care Unit of the Teaching Clinic-Surgical Hospital Comandante Faustino Perez Hernandez, of Matanzas. Materials and methods: a descriptive, cross-sectional study was carried out with the clinical records of 418 patients who attended the Emergency Intensive Care Unit referring acute thoracic pain, from January to December 2019. Results: the most affected age range was the one from 50 to 59 years, for 30.38 %. Male sex predominated, with 30.08 %. Intense physical exercise raised the risk of thoracic pain. The first causes of acute thoracic pain were, in order of frequency, sternocostal osteochondritis, shoulder bursitis, and acute coronary syndrome. Conclusions: It was evidenced that in most of the cases the source of the pain was non-cardiovascular causes, more affecting the male sex. There was significant statistic association between intense physical activity and acute thoracic pain. 71.53 % of the patients was discharged from the unit alive. It is recommended to prioritize the attention of patients referring acute thoracic pain, for their correct classification and care in the shortest possible time.

RESUMEN Introducción: el dolor torácico agudo es una sensación dolorosa que se manifiesta entre el diafragma y la base del cuello. En Cuba, constituye una de las causas más frecuentes de consulta médica. La provincia de Matanzas muestra un comportamiento similar. Objetivo: caracterizar el perfil clínico de los pacientes con dolor torácico agudo en la Unidad de Cuidados Intensivos Emergentes, del Hospital Universitario Clínico Quirúrgico Comandante Faustino Pérez Hernández, de Matanzas. Materiales y métodos: se realizó un estudio transversal descriptivo con las historias clínicas de 418 pacientes que acudieron a la Unidad de Cuidados Intensivos Emergentes, refiriendo dolor torácico agudo, de enero a diciembre de 2019. Resultados: el rango de edad más afectado fue el de 50 a 59 años, para un 30,38 %. Predominó el sexo masculino con el 30,08 %. El ejercicio físico intenso elevó el riesgo de aparición de dolor torácico. Las primeras causas de dolor torácico agudo fueron, en orden de frecuencia, la osteocondritis esternocostal, la bursitis del hombro y el síndrome coronario agudo. Conclusiones: se evidenció que en la mayoría de los casos el origen del dolor fueron causas no cardiovasculares, afectando más al sexo masculino. Existió asociación estadística significativa entre la actividad física intensa y el inicio del dolor torácico agudo. Egresaron vivos de la unidad el 71,53 % de los pacientes. Se recomienda priorizar la atención de los pacientes que refieren dolor torácico agudo, para una correcta clasificación y atención en el menor tiempo posible.

Abstract Introduction: the goal of this work was to evaluate the acceptance of various types of thickeners, specifically modified starch thickener and gum thickener, both with and without flavoring. Patients and methods: a randomized sample of 40 hospitalized patients with oropharyngeal dysphagia was recruited. The taste, smell, and appearance of each type of thickener were evaluated, as well as the volume of liquid ingested by the patients taking each type of thickener (modified starch thickener vs. gum thickener, both with and without flavoring). Results: the overall acceptance of gum thickener was significantly higher than that of modified starch thickener (7.45 (1.57) vs. 5.10 (2.43), respectively; p = 0.001). When a food flavor was added to the thickened water, the overall rating of the product was higher than when no flavor was added (7.70 (1.53) vs. 4.85 (2.16); p < 0.001). The difference between the daily volume of water consumed by the patients who received gum thickeners (928.33 (331.27) mL) and those who received starch thickeners (670.00 (288.35) mL) was statistically significant (p = 0.012). Patient consumption was also higher when flavoring was added as compared to when it was not (943.33 (302.45) mL) vs. (655.00 (304.60) mL; p = 0.005). Conclusion: the acceptances of the thickener and of water intake by patients with dysphagia were both significantly higher when using gum thickeners compared to starch thickeners, and when adding flavoring.

Resumen Se sintetizaron polvos cerámicos de Sr0.5Ba0.5Nb2-xFexO6 (SBNF) para x=0.00, x=0.02 y x=0.03 usando el método de coprecipitación. La estructura de la fase única SBNF con x=0.02 se identificó por difracción de rayos X y refinamiento de Rietveld; La morfología y el tamaño de las partículas se observaron mediante microscopía TEM y SEM-EDS. La caracterización eléctrica mostró que el dopaje con Fe no anuló el comportamiento típico del relajante ferroeléctrico y la caracterización magnética mostró una respuesta ferromagnética débil, lo que sugiere que las muestras obtenidas pueden considerarse como multiferroicas.

Abstract Sr0.5Ba0.5Nb2-xFexO6 (SBNF) ceramic powders for x=0.00, x=0.02 and x=0.03 were synthesized using coprecipitation method. The structure of the SBNF single phase with x=0.02 was identified by X-ray diffraction and Rietveld refinement; the morphology and size of the particles were observed by TEM and SEM-EDS microscopy. Electrical characterization showed that Fe doping did not cancel the typical ferroelectric relaxor behavior and magnetic characterization showed a weak ferromagnetic response, which suggest that the samples obtained can be considered as multiferroic.

Abstract Objective: The aim of the present work was to review the cases of testicular microlithiasis revealed by ultrasound and carry out a review of the literature. Design: Testicular ultrasounds that identified testicular microlithiasis in patients seen at the Hospital “Dr. Manuel Gea González”, within the time frame of 2011 and 2018, were reviewed. Age, study indication, and laterality were among the variables analyzed. Results: Twenty-one ultrasounds revealed testicular microlithiasis in patients ranging from 6 to 24 years of age, with a mean of 16 years. Both testes were affected in 81% of the patients, and the left testis was affected in 29%. The indication for ultrasound was testicular pain in 33% (7 cases), testicular tumor in 14% (3 cases), and testicular torsion in 10% (2 cases). Other causes were varicocele, testicular abscess, and testicular trauma. Study limitations: The conclusions were relative, given the study’s retrospective, observational design. Originality: Microlithiasis has a reported prevalence of 2.4% to 3.8% in children. It is associated with testicular tumors and can cause infertility. A possible cause is nanobacteria that induce testicular calcifications. The study of the disease could modify its treatment and prevent its appearance. Conclusions: Testicular microlithiasis is a rare and little-known disease that can be associated with cancer and infertility. Its etiology appears to be nanobacterial infection. More research on the disease should be carried out.

Resumen Objetivo: El objetivo del presente trabajo es hacer una revisión de los casos reportados por ultrasonido de microlitiasis testicular y hacer una revisión de la literatura. Diseño: Se realizó una revisión de los ultrasonidos testiculares en los que se reportó microlitiasis testicular en el periodo comprendido del 2011 a 2018 en el Hospital “Dr. Manuel Gea González”, las variables que se analizaron fueron: edad, motivo del estudio, lado afectado y otros hallazgos. Resultados: Fueron 21 ultrasonidos con microlitiasis testicular con rango de edad de 6 a 24 años con promedio de 16 años. En el 81% afecto a ambos testículos, y en el 29% afecto el lado izquierdo. En el motivo del estudio el dolor testicular se encontró en el 33 % (7 casos), 14 % por tumor testicular (3 casos), torsión testicular 10% (2 casos), otras causas fueron varicocele, absceso y trauma testiculares. Limitaciones del estudio: Al tratarse de un estudio observacional retrospectivo, las conclusiones obtenidas son relativas. Originalidad: La microlitiasis tiene una prevalencia informada entre el 2.4% y el 3.8% en niños, se asocia a neoplasias testiculares y puede causar infertilidad. Se considera como posible etiología algunas nanobacterias que inducen las calcificaciones testiculares por lo tanto el estudio de esta patología podría modificar su tratamiento y prevenir su aparición. Conclusiones: La microlitiasis testicular es una patología rara y poco conocida que puede estar asociada a cáncer e infertilidad y al parecer su etiología puede ser infecciosa ocasionada por nanobacterias. Es una patología abierta a la investigación.

RESUMEN El síndrome de Sjögren es una entidad multisistémica de naturaleza autoinmune, clásicamente considerada una exocrinopatía debido a la alta frecuencia de síntomas secos (queratoconjuntivitis seca, xerostomía) como resultado de infiltración poliglandular por linfocitos autorreactivos. Sin embargo, menos del 10% de estos pacientes puede iniciar con manifestaciones extraglandulares severas, traducidas en peores desenlaces a largo plazo. Se presenta el caso de una gestante que inició con síndrome de debilidad aguda proximal relacionada con miositis con enfermedad mitocondrial e hipopotasemia severa, en el contexto de acidosis tubular renal distal, como manifestación extraglandular de síndrome de Sjögren primario. Se discuten brevemente manifestaciones neurológicas de esta entidad, incluyendo aquellas secundarias a trastornos metabólicos precipitados por compromiso autoinmune.

ABSTRACT Sjögren's syndrome is a multisystemic autoimmune disorder. It is classically considered as an exocrine disease, given the high frequency of dry symptoms (keratoconjunctivitis sicca, xerostomia) as a result of poly-glandular infiltration by autoreactive lymphocytes. However, less than 10% of these patients can onset with severe extra-glandular manifestations, resulting in worse long-term outcomes. The case of a pregnant woman is presented, who debuted with acute proximal weakness syndrome related to myositis with mitochondrial pathology and severe hypokalaemia in the context of distal renal tubular acidosis, as an extra-glandular manifestation of primary Sjögren's syndrome. Neurological manifestations of this condition are briefly discussed, including those secondary to metabolic disorders precipitated by autoimmune compromise.

Resumen Objetivo: Establecer valores de referencia de las neuroconducciones motoras y sensitivas y de las respuestas tardías para el laboratorio de electrodiagnóstico del Hospital Universitario San Ignacio. Materiales y métodos: Se realizaron estudios de neuroconducción sensitiva y motora de las 4 extremidades, a 77 voluntarios sanos entre los 18 y los 65 años de edad, para un total de 154 registros, usando una técnica estandarizada para la medición. Resultados: Se realizaron neuroconducciones motoras que midieron latencia, amplitud y velocidad de los nervios mediano, cubital, tibial y peronero. También se realizaron neuroconducciones sensitivas que midieron latencia y velocidad de los nervios mediano, cubital y sural. Un test de Shapiro-Wilk encontró que los parámetros de amplitud para las neuroconducciones sensitivas no seguían una distribución normal, por lo cual se hizo análisis de percentiles. Solo el sexo mostró una diferencia estadísticamente significativa para los parámetros de amplitud del nervio tibial (p = 0,0099), siendo mayor en mujeres, y latencia del nervio peroneo (p = 0,0091), siendo mayor en hombres. Conclusiones: Se establecieron los parámetros de referencia para las neuroconducciones motoras, sensitivas y las respuestas tardías para el laboratorio de electrodiagnóstico del Hospital Universitario San Ignacio, los cuales se correlacionan en su mayoría con los datos de referencia actuales, con ciertas diferencias que podrían estar relacionadas con la estatura y el sexo; sin embargo, se requieren estudios adicionales para establecer esta diferencia.

Abstract Objective: To establish reference values of motor and sensory nerve conductions and late responses for the Electrodiagnostic Laboratory of Hospital Universitario San Ignacio. Materials and Methods: Sensory and motor nerve conduction studies were performed on 77 healthy volunteers between 18 and 65 years old, for a total of 154 analyzes, using a standardized technique for measurement. Results: Motor nerve conductions were performed measuring latency, amplitude and conduction velocity for the median, ulnar, tibial, and peroneal nerve. Sensory nerve conductions were performed measuring latency and conduction velocity for the median, ulnar, and sural nerve. A Shapiro-Wilk test was performed, finding that the amplitude parameters for sensory nerve conductions did not follow a normal distribution, so percentile analysis was performed. Only sex showed a statistically significant difference for the parameters of tibial nerve amplitude (p = 0.0099) being greater in women, and latency of the peroneal nerve (p = 0.0091) being greater in men. Conclusion: Normal parameters were established for motor and sensory nerve conductions and late responses for the Electrodiagnostic Laboratory of Hospital Universitario San Ignacio, which mostly correlate with the current reference data, with certain differences that could be related with height and sex. However, additional studies are required to enstablish this difference.

ABSTRACT The need to increase the quality levels of universities, mainly in Latin America, has allowed the development of models for the evaluation of higher education institutions and for the accreditation of the programs that are developed in it, however, Models should not act in the universities on time but should form the strategic planning and management system of the university so that systematically contribute to compliance with the criteria and indicators that are part of the quality pattern. The proposed procedure has the objective of finding the appropriate correspondence between the evaluation and accreditation model and the management system of the university. The application of the procedure in the Technical University of Manabí contributed to that this university improved the levels of national accreditation from category "D" to "B" and the international visibility.

RESUMEN La necesidad de incrementar los niveles de calidad de las universidades principalmente en el ámbito latinoamericano ha permitido que se desarrollen modelos para la evaluación de las instituciones de educación superior y para la acreditación de los programas que en ella se desarrollan. Sin embargo, estos modelos no deben actuar en las universidades puntualmente sino que deben formar de la planificación estratégica y del sistema de gestión de la universidad para que de forma sistemática se contribuya al cumplimiento de los criterios e indicadores que forman parte del patrón de calidad. El procedimiento propuesto tiene el objetivo de encontrar la adecuada correspondencia entre el modelo de evaluación y acreditación y el sistema de gestión de la universidad. La aplicación del procedimiento en la Universidad Técnica de Manabí contribuyó a que esta universidad mejorara los niveles de acreditación nacional desde la categoría "D" hasta la "B" y la visibilidad internacional.

Abstract Background: Postoperative intussusception is an unusual complication in children; the incidence is 0.01-0.25%. Clinical Case: Female of 11 months who underwent colostomy, 48 h later presents abdominal pain, vomiting gastrobiliar and abdominal distension. A laparotomy was performed, finding a double ileo-ileal invagination 60 cm from the ileocecal valve. Discussion: The postoperative intestinal invaginations are extremely rare and most of them occur within the first 7 days. The etiology of postoperative intussusception is unknown. Conclusions: Postoperative children with intestinal occlusion, intussusception should be suspected and an immediate laparotomy should be performed.

Resumen Antecedentes: La invaginación posoperatoria es una complicación inusual en niños. Su incidencia es del 0.01-0.25%. Caso clínico: Niña de 11 meses a quien se realizó colostomía y 48 horas después presentó dolor abdominal, vómito gastrobiliar y distensión abdominal. Se realizó laparotomía y se encontró una doble invaginación íleo-ileal a 60 cm de la válvula ileocecal. Discusión: Las invaginaciones intestinales posoperatorias son extremadamente raras y la mayoría se presentan dentro de los primeros 7 días. La etiología de la invaginación posoperatoria es desconocida. Conclusiones: En niños operados con oclusión intestinal debe sospecharse invaginación intestinal y realizar una laparotomía inmediata.

Abstract: Studying activity patterns of canopy mammals provides information on the biology of these species. However, the challenges of reaching and sampling the forest canopy restrict the information available on activity patterns. This study aimed to describe the activity patterns of canopy mammals, and analyze their temporal overlap, in the Santa Gertrudis Ecological Reserve, State of Veracruz, Mexico. Camera trap records were obtained from February 2016 to February 2017. Nine camera traps were set in the study area, separated between 300 and 1500 m from each other, along a straight line in the forest canopy (~ 8 to 12 m above the ground). Cameras were affixed to a trunk above a branch that was perpendicular to the line and overlapping a neighboring tree. A total of 12 mammal species that use the tree stratum were recorded, including two diurnal and ten nocturnal species. The five species for which at least ten records were obtained were included in the activity pattern analyses. Four of these are nocturnal species and showed temporal overlap values (Δ1) ranging from 0.69 to 0.9. Four of the 12 species recorded are listed in an extinctionrisk category as per the Norma Oficial Mexicana NOM. This is one of the first studies providing ecological information on activity patterns of canopy mammals in Mexico.

Resumen: El estudio del patrón de actividad de los mamíferos del dosel ayuda a complementar la información básica sobre la biología de estas especies. Sin embargo, la dificultad por acceder al dosel para llevar a cabo el muestreo limita la información existente sobre sus patrones de actividad. El objetivo de la presente contribución fue describir el patrón de actividad y analizar el traslape temporal de los mamíferos de dosel en la Reserva Ecológica de Santa Gertrudis, Vega de Alatorre, Veracruz, México. Se obtuvieron los registros mediante cámaras-trampa durante un año de muestreo de febrero 2016 a febrero 2017. En el área se colocaron nueve trampas-cámara con una separación entre 300 m y 1.5 km en línea recta entre el dosel (~8 a 12 m de altura), sujetadas al tronco por encima de una rama en posición perpendicular y con conexión con otro árbol. Se registró un total de 12 mamíferos que hacen uso del estrato arbóreo, de los cuales dos presentaron actividad diurna y 10 actividad nocturna. Únicamente de cinco obtuvimos 10 o más registros que nos permitieron llevar a cabo los análisis de patrones de actividad. Cuatro de estas especies fueron nocturnas y presentaron un coeficiente de traslape temporal de entre Δ1 = 0.69 a 0.9. De las 12 especies registradas cuatro se encuentran catalogadas bajo alguna categoría de riesgo dentro de la legislación mexicana. Este estudio es uno de los primeros en aportar información ecológica con respecto a los patrones de actividad de un ensamble de mamíferos arborícolas en México.

Abstract We examined the relationships among gender, planning, and academic expectations through the testing of two alternative models with latent variables tested with LISREL 8.80: one model considered planning as a mediator of the relationship between gender and academic expectations, and the other model considered academic expectations as mediators of the relationship between gender and planning. Participants were 662 first-year higher-education students from two academic years, predominantly female (60%) and mainly with majors in the juridical-social field (66.2%). The Inventario sobre Estrategias Metacognitivas (IEM; Inventory of Metacognitive Strategies) and the Academic Perceptions Questionnaire (APQ) were applied at the beginning of the first semester to assess planning and academic expectations, respectively. Multigroup confirmatory factor analysis was used to test the IEM’s structure after examining its psychometric properties with the sample from the first academic year (N = 338). The test of the alternative mediation models with the full sample indicates that the best model was that with planning as a mediator. In this model, gender directly predicted only two APQ academic expectations, but with the mediation of planning, gender predicted all seven academic expectations. Women showed higher levels of academic expectations and planning than did men. The results are discussed at both the theoretical and practical levels.

ABSTRACT Atrial myxoma is a benign primary cardiac tumor that is mostly found in the left atrium. This paper aims to describe the clinical presentation of a right atrial myxoma through the case report of a 54-year-old patient diagnosed with pulmonary hypertension syndrome secondary to the above-mentioned cardiac tumor. The clinical features of myxomas are determined by their location, size and mobility. In this case, intracardiac obstruction produced by the myxoma, with paradoxical movement of the septum, resulted in ventricular filling alterations, low cardiac output signs and severe pulmonary hypertension. Immediate clinical and surgical management after diagnosis successfully prevented the development of major complications. This case highlights the paramount importance of clinical judgment and the use of various cardiac imaging techniques in decision making.

RESUMEN El mixoma auricular es un tumor cardíaco benigno de origen primario que se localiza mayormente en la aurícula izquierda. El presente trabajo tiene como objetivo describir las formas clínicas de presentación de un mixoma de aurícula derecha, a través de la presentación de un caso con el diagnóstico de síndrome de hipertensión pulmonar secundaria al mencionado tumor cardíaco, en una paciente de 54 años de edad. Las características clínicas de los mixomas están determinadas por su localización, tamaño y movilidad. En este caso, la obstrucción intracardíaca producida por el mixoma, con movimiento paradójico del septum, dió lugar a alteraciones en el llenado ventricular, signos de bajo gasto e hipertensión pulmonar grave. El abordaje clínico y quirúrgico inmediato tras el diagnóstico evitó el desarrollo de complicaciones mayores. Este caso enfatiza la vital importancia del juicio clínico y el uso de diversas técnicas de imagen cardíaca en la toma de decisiones.
