Left ventricular endoaneurysmorrhaphy: effect on left ventricular size, shape and function.
Left ventricular (LV) endoaneurysmorrhaphy is a relatively new surgical procedure with excellent results. Forty-five patients underwent surgical repair of LV aneurysm with LV endoaneurysmorrhaphy from 1991 to 1995. The main indication for operation was angina pectoris (71%). Concomitant myocardial revascularization was performed in 97% of the patients. The operative mortality rate was 2.2%. Pharmacologic inotropic support was required in 31% and mechanical support in 15%. Mean echocardiographic ejection fraction improved from 29.6% preoperatively to 48.3% postoperatively (p <0.001). LV end-diastolic volumes were 195 +/- 63 and 118 +/- 44 ml before and after surgery (p <0.01). Intraoperative transesophageal echocardiography revealed normal or near-normal LV shape in all cases. The mean follow-up was 34.0 +/- 9.2 months (16-50 months) and 1 patient died 9 months postoperatively. We conclude that endoaneurysmorrhaphy improves LV geometry and function in patients with LV aneurysms and can be performed with low surgical risk even in patients with large aneurysms and severely depressed LV function. ........
