Ventricular septal defect is an infrequent but often catastrophic complication. Occasional patients can be treated conservatively until an interval of 3-4 weeks postinfarct, a propitious time for surgical repair of the septal defect. However, the vast majority of patients who sustain interventricular septal rupture will not survive more than a few days unless the problem is dealt with promptly and definitively. In anterior or apical defect secondary to acute anterior myocardial infarction, prosthetic fabric replacement of septum is necessary for permanent closure of septal defect. The use of prosthetic fabric prevents tearing out of sutures used to close the defect or the ventriculotomy itself because of undue tension on the friable myocardium
