Abstract

Myocardial damage after infarction is a common sequela in patients with coronary occlusive disease. The extent of injury varies and may be localized or diffuse. Since March 1989, the authors have used a new surgical repair technique that employs an intracavitary patch of Dacron fabric or glutaraldehyde-treated pericardium to exclude the hypokinetic or fibrotic myocardial segment. An elliptical configuration preserves the contour and volume of the ventricular cavity. After securing the patch, the ventriculotomy is closed with a simple continuous suture. Through July 31, 1991, 136 patients underwent repair using this technique. Of these patients, 100 (group I) had neither sustained an acute myocardial infarction (within 30 days before surgery) nor had undergone previous cardiac surgery, whereas 36 (group II) had sustained an acute myocardial infarction or had undergone previous cardiac surgery. In group I, four (4%) died within 30 days of surgery, and seven died later, resulting in a 6-month survival of 90.5% and a 1-year survival of 85.3%. In group II, 11 (30.6%) died within 30 days of surgery, and three died later. Functional class improved after repair in 95.7% of patients in group I and all patients in group II. In both groups, ejection fraction improved significantly (p less than 0.0001, group I; p less than 0.0001, group II). By eliminating the need for epicardial buttresses to repair the ventriculotomy, myocardial revascularization has been possible in most patients. This method of intraventricular repair is also appropriate for patients with calcified aneurysms, acquired ventricular septal defects, and acute ventricular rupture.
