Rupture of ventricular septum following myocardial infaction is one of the serious complication of coronary artery disease. The characteristic manifestations are sudden appearance of a harsh systolic murmur, precordial pain, cardiovascular collapse and permit early diagnosis. We report two cases of successful repair of postinfaction ventricular septal defect. The infarcted area was anterior wall of ventricle and VSD was placed near apex of heart in two cases all. VSD was closed with pledgetted Dacron patch and incised wall was sutured with Teflon felt and concomitant coronary artery bypass graft was done respectively .Postoperative courses were uneventful.
