RESUMO

Using bovine pericardium instead of Dacron for grafting, we performed ventricular endoaneurysmorrhaphy (Cooley's technique) in 13 patients with postmyocardial infarction left ventricular aneurysm. Twelve patients were men and 1 was a woman; their ages ranged from 38 to 67 years (mean, 51.2 +/- 11.4 years). Eight patients had large anterolateral aneurysms, 4 had apical aneurysms, and 1 had a false inferior aneurysm. Postoperatively, the mean cardiac index increased from 2.07 +/- 0.50 to 3.09 +/- 0.99 L/min/m2 (p < 0.05), with a mean percentage increase of 50.17% +/- 37.03%. No patient required postoperative mechanical circulatory assistance, and pharmacologic support could be withdrawn soon after surgery. All patients had uncomplicated recoveries and were asymptomatic upon discharge, at a mean time of 9.0 +/- 2.3 days after surgery. We conclude that ventricular endoaneurysmorrhaphy provides excellent initial results, and we believe, through subjective analysis of ventriculograms, that the use of bovine pericardium for grafting produces better functional results than does the use of Dacron.
