[Ventricular endoaneurysmorrhaphy for the left ventricular aneurysm after myocardial infarction: technique and left ventricular function].
A 54-year-old male with a left ventricular aneurysm and angina after myocardial infarction underwent Cooley's ventricular endoaneurysmorrhaphy with single coronary artery bypass grafting. On cardiopulmonary bypass, an elliptial Dacron felt patch was fashioned to replace the diseased area in the left ventricular cavity, restoring normal shape, contour and volume to the ventricule and stabilizing the still viable and functioning myocardium, and sutured to transition zone between viable myocardium and the fibrotic scarred area. At this time, single coronary bypass grafting (LITA to diagonal branch) was done. His post operative course was uneventful. The left ventricular systolic and diastolic function improved significantly in each variable measured on left ventriculogram analysis.
