Postinfarction ventricular septal defect repair: retrospective thoughts and historical perspectives.
Evolution of surgical techniques for repair of postinfarction ventricular septal rupture initially involved differentiation of these lesions from prior experience with surgical approaches to congenital ventricular septal defects, which were in the main not applicable. Second, understanding of the differing anatomical locations of postinfarction ventricular septal defects required innovation in terms of the location of the cardiotomy and type of repair necessary to achieve a successful result in any given patient. The gradual appreciation of different clinical courses pursued by patients after postinfarction ventricular septal rupture both in terms of location of the defect and the degree of right ventricular functional impairment has led to increased urgency relative to the timing of surgical repair. The incorporation of specific anatomical concepts of surgical repair and better understanding of the time course of physiological deterioration of patients can ultimately lead to an integrated approach aimed toward improved salvage of patients suffering this catastrophic complication of acute myocardial infarction.
