    Abstract:
    Postinfarction rupture of the interventricular septum is usually fatal without surgical intervention and requires urgent closure. Between 1989 and 2003 twenty consecutive patients (15 male, 5 female), underwent postinfarction ventricular septal rupture (VSR) repair. Mean age of the patients was 62.05 +/- 7.51 years. Fifteen patients were operated within 48 hours after myocardial infarction. Patch reconstruction was performed in all patients. Infarct locations were anterior in 65%, posterior in 35%. Coronary artery surgery was performed in 14 patients (70%). Hospital mortality was 30% (6 patients). Four patients were presented for surgical therapy with frank cardiogenic shock or low cardiac output syndrome. A residual shunt was detected in 4 patients and three of these patients were reoperated. One of them, who has been reoperated on the first day of the postoperative period, did not survive. The statistical analysis of the patients' records demonstrated that time period between MI and surgery, applied additional CABG procedure, the sex of the patients and the site of the rupture are significant factors influencing in-hospital mortality. Preoperative condition, age of the patients and the number of the affected coronary vessels do not have an important effect on the mortality. Postinfarction ventricular septal rupture is a fatal complication of the myocardial infarction and must be treated surgically. The time interval between septal rupture independent from the preoperative haemodynamic condition, the location of the defect and additional myocardial revascularization procedure are the factors influencing the early outcome.
