          Abstract

          Com o objetivo de avaliar tardiamente o efeito da aneurismectomia do ventrículo esquerdo quanto a sintomatologia e função ventricular global, foram analisados 40 pacientes consecutivos operados de agosto/87 a novembro/94, com um período de seguimento de 12 a 99 meses. A localização mais comum foi a ântero-medial e a maioria dos pacientes apresentava um quadro misto de angina e ICC. A pd2VE média preoperatoria foi de 25,9 mmHg. Cinco (12,5%) faleceram durante a internação, por insuficiência miocárdica aguda e 6 (15%), durante o pós-operatório tardio. Quando se divide a série em dois grupos, aqueles operados de 1991 a 1994 (últimos 22 pacientes) mostram uma sobrevida de 91% ao final de 4 anos. Dos 29 sobreviventes, 12 (30%) encontram-se assintomáticos, enquanto que 42,5% cursam com algum grau de angina ou ICC. O ecocardiograma bidimensional demonstrou normalização dos diâmetros ventriculares, das frações de ejeção e encurtamento em apenas 43% dos casos. Ao final de um ano, somente 50% dos pacientes estão livres de sintomas. Em conclusão, a aneurismectomia do ventrículo esquerdo promoveu melhora sintomática na maioria dos pacientes, com mortalidade aceitável, embora não totalmente confirmada pelos índices de função global ao ecocardiograma bidimensional.

          Forty consecutive patients operated on between August 1987 and November 1994 were analysed, aiming at the late assessment of left ventricular aneurysmectomy in terms of symptomatology and global ventricular function. The follow-up ranged from 12 to 99 months. The most common location was anteromedial and most of the patients had both angina and CHF. The average preoperative LVEDP was 25.9 mmHg. Five patients (12.5%) died during hospitalization, due to acute myocardial failure, and 6 (15%) during the late postoperative period. When the series is divided into two groups, the survival rate among those operated on between 1991 and 1994 (the last 22 patients) is 91 % after 4 years. Of the 29 survivors, 12 (30%) are asymptomatic, while 42.5% have some degree of angina or CHF. Two-dimensional echocardiography showed normalization of the ventricular diameters, ejection fraction and percent fractional shortening in only 43% of the cases. After 1 year, only 50% of the patients are free of symptoms. The conclusion is that left ventricular aneurysmectomy caused symptomatic improvement in most of the patients, with an acceptable mortality rate, though nottotally confirmed by the indices of global function in two dimensional echocardiography.

              Influence of left ventricular aneurysm on survival following the coronary bypass operation.

              Patients having coronary bypass and aneurysm resection (N = 40) or aneurysm plication (N = 32) were compared with patients having coronary bypass without aneurysm (N = 2782). Unlike other series, the primary indication for surgery in the aneurysm patients was angina pectoris, with heart failure playing a secondary role. Multivessel disease was present in 83% of the patients with aneurysm. Total occlusion of the anterior descending coronary artery was more prevalent in the group of patients who had aneurysmectomy (75%) than in rhe group of patients who had plication (38%), and more grafts/patient could be performed in the plication group (2.6 vs 2.0). Location of the aneurysm was most often anteroapical (N = 55) and infrequently inferior (N = 6). Septal wall motion was akinetic or aneurysmal in 47% of the aneurysmectomy group, and 10% of the plication group. Postoperative requirements for inotropes or intra-aortic balloon assist was much higher in the aneurysm group (aneurysmectomy or plication) than in patients without aneurysm having bypass. Hospital mortality for aneurysm patients was 2.7% versus 1.4% in patients without aneurysms having coronary bypass. The actuarial survival rate at 42 months for all aneurysm patients was 90%. Improvement in anginal symptoms after plication and coronary bypass (96%) was more frequent than with aneurysmectomy and coronary bypass (76%) and this was attributed to larger viable muscle mass and greater revascularization. Although two-thirds of patients having surgery for aneurysms had improvement in heart failure symptoms after operation, 30% of those having aneurysmectomies and 35% of those having plications said they were unimproved after surgery. However, this could be explained by the finding that a significant number (35% of the aneurysmectomy and 45% of the plication group) were in heart failure Class I prior to operation. Hospital mortality has been progressively reduced and late survival increased by the surgical treatment of left ventricular aneurysm, primarily through early operation at a time when coronary bypass can be used as an adjunct to aneurysm resection or plication.
