BACKGROUND: Recent advances in surgical techniques for the repair of @entity1002 ( @entity1002 ) include the use of an endoventricular patch to exclude the @entity439 . This technique has replaced conventional linear plication of the @entity439 . The endoventricular patch technique remodels the left ventricular cavity to a more physiological geometry that improves function. METHODS AND RESULTS: From December 1989 through November 1993, 45 @entity1 underwent an LVA repair with an endoventricular patch. This procedure was performed in association with coronary artery bypass grafting in 40 @entity1 . Twenty-eight @entity1 (62.2%) also had nonguided encircling subendocardial incisions. Operative procedures included 7 emergency operations, 3 concomitant valve procedures, and a mean of 2.2 bypass grafts per @entity1 . Eight @entity1 had previous cardiac operations. Hospital mortality was 15.6% (7/45) for all @entity1 and 9.1% (3/33) for nonemergent revascularization and LVA repairs. Ejection fraction improved from a mean of 25.8% preoperatively to 37.8% postoperatively; the mean New York Heart Association classification improved from 3.5 to 1.5. Of @entity1 known to have preoperative @entity943 (inducible or @entity944 ), 69% were not inducible postoperatively without antiarrhythmic medication. Survival from late @entity204 (including death of unknown origin) was 86.5% at 2 years. Freedom from documented @entity943 was 94.3% at 2 years. CONCLUSIONS: These results indicate that the patch endoaneurysmorrhaphy technique can provide an excellent functional and physiological outcome in @entity1 with @entity1002 and severely @entity67 .
