Background: Postinfarction ventricular septal rupture (PI-VSR) is a rare but devastating complication of acute myocardial infarction (AMI). Risk stratification in the acute phase is crucial for decision-making, and this study analyzed the risk factors for early mortality and the effects of various management options on the outcome of PI-VSR patients in the era of percutaneous intervention. Methods: A total of 96 patients with PI-VSR were identified and divided into an acute-phase survivor group (n = 46, survived ≥2 weeks after admission) and a nonsurvivor group (n = 50, died within 2 weeks after admission). Percutaneous closure was considered in acute-phase survivors. Patients were followed up for a mean 47 (quartiles 15–71) months by clinical visit or telephone interview. Results: The overall acute-phase (i.e., < 2 weeks after the diagnosis of PI-VSR) mortality rate was 52%. Female sex and Killip Class III–IV at admission were associated with an increased risk of acute-phase death. Of the 46 patients who survived ≥2 weeks, 20 underwent interventional occlusion and the procedure was successful in 19. Percutaneous closure in the acute-phase survivor group improved the immediate (21% in-hospital mortality rate) and long-term (53% mortality) outcomes. Conclusions: Patients with PI-VSR are at a high risk of acute-phase mortality. Female sex and severe cardiac dysfunction at admission are linked with a high rate of acute-phase deaths. Percutaneous closure in acute-phase survivors results in favorable short- and long-term benefits for PI-VSR patients.
