Ventricular septal rupture (VSR) is a serious complication of ST-elevation myocardial infarction (STEMI) and surgery is the reference treatment. We aimed at describing trends in management and mortality during the last four decades and reporting mortality predictors in these patients. We conducted a single-center retrospective study of patients sustaining a VSR from 1981 to 2020. We screened 274 patients and included 265 for analysis. The number of patients decreased over the years: 80, 88, 56, and 50 in each 10-year time span. In-hospital mortality decreased significantly since 1990 (logrank 0.007). The median age was 72.0 years IQR [66–78] and 188 patients (70.9%) were operated on. IABP was used more routinely ( p  < 0.0001). In-hospital mortality was assessed at 66.8% (177 patients) and main predictors of death were a time from MI to surgery < 8 days HR 2.7 IC95% [1.9–3.8] p  < 0.0001, a Killip class > 2 HR 2.5 IC [1.9–3.4] p  < 0.0001 and Euroscore 2 > 20 HR 2.4 IC [1.8–3.2] p  < 0.0001. A “time from MI to surgery” of 8 days offers the best ability to discriminate between patients with or without mortality. The ability of “Euroscore 2 and Killip” to detect the patients most likely to wait 8 days for surgery was at 0.81 [0.73–0.89] p  < 0.0001. Mortality remains high over the years. Euroscore 2, Killip class, and time from MI to surgery are the main mortality predictors. Patients with a Killip < 3 and a Euroscore < 20 should be monitored at least 8 days since MI before being referred to surgery.
