BACKGROUND Postinfarction ventricular septal rupture (VSR) is a lethal complication with high mortality. The aim of this study was to evaluate our surgical strategy and results of VSR. METHODS Between 1996 and 2008, 13 consecutive patients underwent operation for VSR at our hospital. All patients required emergent operation because of severe cardiogenic shock. Surgical procedure consisted of endocardial patch repair with infarct exclusion, so called "Komeda-David operation". In patients with multiple coronary artery disease, myocardial revascularization was done simultaneously. RESULTS These patients were divided into 2 groups according to the location of VSR. There were 9 patients of anterior VSR. Two of them could not be weaned from cardiopulmonary bypass and died of severe low output syndrome (LOS) at early postoperative period. The site of infarction in both patients was broad anteroseptal region including right ventricle. On the other hand, there were 4 patients of inferior VSP. Two of these patients were lost due to LOS. One patient was complicated with left ventricular free wall rupture. In another patient, infarction was extended proximally toward the mitral annulus and papillary muscles. Both cardiopulmonary bypass time and aortic crossclamp time were significantly longer in inferior VSR than in anterior region. There was no late death in 2 groups. CONCLUSIONS Despite improvements of surgical procedures, such as infarct exclusion technique, the operative mortality remains high in cases with broad infarction and/or right ventricular infarction. In these particular circumstances, in should be mandatory to consider the optimal timing of operation and the modification of surgical technique itself.
