Since 1994, three patients more than 80 years of age underwent early repair of ventricular septal rupture complicating acute myocardial infarction at our hospital. The infarction exclusion technique introduced by David and Komeda was employed. Average aortic clamp time, cardiopulmonary bypass time and operation time were 83 minutes, 129 minutes and 228 minutes, respectively. No hemostatic suture were required to the left ventricular suture line. All patients survived. One patient with posterior ventricular septal rupture had residual shunt and necessitated transient hemodialysis but recovered. Thus, the infarction exclusion technique seems to be useful in the elderly with unfavorable tissue fragility.
