ABSTRACT

OBJETIVO: Avaliar os resultados tardios da técnica extra-anatômica para correçäo da coarctaçäo do arco aórtico em adultos. CASUíSTICA E MÉTODOS: Entre 1979 e 2000, 15 pacientes foram submetidos à interposiçäo de tubo de Dacron entre a aorta ascendente e descendente para correçäo da coarctaçäo do arco aórtico. Onze (73,3 por cento) pacientes eram do sexo masculino e a média de idade foi de 30,8 ± 12,1 anos (18 a 61 anos). A esternotomia mediana, com abordagem do pericárdio posterior, foi utilizada em 13 (86,7 por cento) pacientes e a toracotomia lateral esquerda em 2 (13,3 por cento). Em 3 (20,0 por cento) pacientes foram realizados procedimentos associados e 4 (26,7 por cento) eram reoperaçöes. Os pacientes foram acompanhados por um período de 30 dias a 21 anos (média de 6,9 ± 6,7 anos) com avaliaçäo clínica, ecocardiográfica e estudo angiográfico com ressonância magnética. RESULTADOS: Näo ocorreram complicaçöes neurológicas e nem mortalidade imediata ou tardia. Näo houve necessidade de reoperaçöes e nem complicaçöes tardias com o enxerto. Todos os pacientes encontram-se assintomáticos e com o enxerto pérvio confirmado pelo ecocardiograma. Cinco (33,3 por cento) pacientes apresentam hipertensäo arterial sistêmica de grau leve. Em 11 (73,3 por cento) pacientes foi realizado o estudo angiográfico com ressonância magnética, mostrando enxerto com bom funcionamento a longo prazo. CONCLUSÄO: A técnica extra-anatômica, com interposiçäo de tubo de Dacron entre a aorta ascendente e descendente, para correçäo da coarctaçäo do arco aórtico é uma operaçäo segura, com baixa morbidade e mortalidade. Os bons resultados a longo prazo mostram que esta técnica pode ser uma alternativa segura e menos invasiva, para a correçäo de coarctaçäo do arco aórtico ou recoarctaçäo em adultos

ABSTRACT

PURPOSE--To study the incidence of ischemic mitral regurgitation (MR) and the mortality. METHODS--One-hundred-five cases of acute myocardial infarction (AMI) with MR were reviewed. Patients were divided in two groups: group A-59 (56.2 per cent) necropsied patients without previous surgical procedures to correlate clinical pictures with the aim to determine the cause of death; group B-46 (43.8 per cent) patients were submitted to surgical treatment. This group was subdivided in mild, moderate and severe forms of MR, and studied comparatively the type of surgical treatment and its evolution. RESULTS--Group A-23 (39 per cent) patients with mild forms and predominant ischemic heart disease, responsible for death; 18 (30.5 per cent) patients without previous diagnosis, masked by myocardial failure and 18 (30.5 per cent) with severe MR and coronary heart disease; group B-14 (30.4 per cent) patients died at the immediate post-operatory period. Higher mortality associated to ejection fraction (EF) below 35 per cent (47.6 per cent; p = 0.022), severe MR (41.7 per cent; p = 0.044) and cardiogenic shock (52.9 per cent; p = 0.14). In 41 (89.1 per cent), the mitral valve repair was combined to coronary artery bypass grafting operation (CABG), in 4 (8.7 per cent) this last procedure was made without mitral repair and in the remaining patients the surgery was limited to the valve. Mitral valvuloplasty was performed in 23 (50 per cent) patients with 3 (13 per cent) deaths, and in 19 (42.3 per cent) the mitral valve was replaced with 9 (47.4 per cent) deaths. CONCLUSION--The prognosis is related to the grade of EF and to the severity of MR. In mild to moderate forms, the surgical indication is due to the associated coronary heart disease and the valvuloplasty is preferred, in this instance. In severe forms, surgical intervention must be performed as soon as possible, before cardiogenic shock appears
