Relatamos um caso em que a valvoplastia aórtica percutânea foi utilizada como primeira escolha, em procedimento de urgência, para o tratamento de estenose aórtica grave em paciente gestante de 16 anos, com congestão pulmonar sem controle clínico. Descrevem-se o quadro clínico, a fisiopatologia, os aspectos diagnósticos e indicações do tratamento percutâneo. A estenose valvar aórtica congênita, quando grave, é rara em crianças e jovens. A valva aórtica bicúspide ocorre em 3% a 6% com doença cardíaca congênita e, quando relacionada com fusão comissural, pode haver estenose importante já na infância. A associação de estenose aórtica congênita grave com gestação é de difícil controle clínico e alto risco de mortalidade materna e fetal, principalmente quando se manifesta com sintomas de congestão pulmonar1,².

We report the case of a 16-year-old pregnant patient with severe aortic stenosis and pulmonary congestion clinically uncontrolled, in whom percutaneous balloon aortic valvuloplasty was used as the first choice of treatment in an emergency procedure. The clinical findings, pathophysiology, diagnostic features, and indications for percutaneous treatment are reported. Severe congenital aortic stenosis is rare in children and young individuals. Bicuspid aortic valve occurs in 3% to 6% of patients with congenital heart disease; when associated with commissural fusion, significant stenosis may be present in childhood. The association of severe congenital aortic stenosis and pregnancy is difficult to control clinically, carrying a high risk of maternal and fetal mortality, mainly when manifested with symptoms of pulmonary congestion 1,2.

OBJECTIVE: To assess the major causes of surgical morbidity and mortality in patients with infective endocarditis operated upon in a regional cardiology center. METHODS: Thirty-four patients underwent surgical treatment for infective endocarditis. Their ages ranged from 20 to 68 years (mean of 40.6) and 79% were males. Their NYHA functional classes were as follows: IV - 19 (55.8%) patients; III - 12 (35.2%) patients; II - 3 (8.8%) patients. Blood cultures were positive in only 32% of the cases. Eight patients had already undergone previous cardiac surgery, whose major indication (82.3%) was heart failure refractory to clinical treatment. RESULTS: Four (11.7%) patients died at the hospital. Follow-up was complete in 26 (86%) patients. Five (14.7%) patients died later, 12, 36, 48, 60, and 89 months after hospital discharge. Of the 21 patients being currently followed up, 1 is in NYHA functional class III, and 5 in NYHA functional class II. CONCLUSION: A high degree of clinical suspicion, at an early diagnosis, and indication of surgical treatment prior to deterioration of left ventricular function and installation of generalized sepsis may improve prognosis.

RAvaliaram-se as indicações, as alterações e os resultados cirúrgicos de 28 pacientes, operados por endocardite infecciosa (EI) no período de 1983 a 1994. O diagnóstico clínico foi confirmado pela ecocardiografia e pela cineangiocardiografia. Dos pacientes, 65% eram do sexo masculino e 25% do feminino, com média de idades de 35,21 (14 a 67) anos. Noventa e três por cento dos pacientes estavam em classe funcional III e IV (NYHA). O tempo decorrido entre o diagnóstico e a cirurgia foi em média de quatro semanas e meia (1 a 363 dias). A hemocultura foi positiva em 25% dos casos e os germes mais freqüentemente encontrados foram estreptococos e estafilococos. A valva aórtica foi a mais acometida e as vegetações foram as lesões mais comumente encontradas. O tratamento cirúrgico utilizado foi a plastia valvar em 2 casos e a substituição valvar por prótese em 26.Complicações ocorreram em 39,28% dos casos, com 5(18%) mortes. Conclui-se que, embora rara, a EI é doença grave e, se não prevenida com adequada antibiótico-profilaxia ou tratada em tempo hábil, o paciente terá conseqüências graves, podendo, até mesmo, falecer.

The indication, surgical pathology and the results of surgical treatment of 28 patients operated on for infectious endocarditis between 1983 and 1994 are here evaluated. The clinical diagnosis was confirmed by echocardiography and cineangiography. Seventy-five percent of the patients were male and 25% female, with the mean age of 35.2 (14 to 67) years old. Ninety three percent were in functional class III or IV (N Y H A). Elapsed time between diagnosis and surgery was around 4 weeks (1-363 days). A positive hemoculture was present in 25% of the cases and the commonest bacteria found were streptococcus and staphilococcus. The aortic valve was the one usualy affected and vegetations was the usual finding. Surgical treatment consisted of valvuloplasty in 2 cases and valve replacement in 26. Complications were present in 39.28% of the cases, which resulted in the death of five of them (18%). We conclude that, although rare, the infectious endocarditis is a serious disease; if not prevented with adequate antibiotic prophilaxis or treated in due time, serious complications or even death might occur.
