    Abstract:
    BACKGROUND: Ventricular septal rupture (VSR) is a rare but life-threatening complication after acute myocardial infarction. Although surgical correction is challenging and associated with high mortality, it remains the treatment of choice. This systematic review and meta-analysis aimed to evaluate the early outcome of surgical VSR repair. METHODS: We searched electronic databases from January 1998 to February 2020. Studies reporting patients undergoing surgical treatment for VSR were analyzed. The primary outcome assessed was operative mortality. Differences were expressed as odds ratios (ORs) with 95% confidence intervals (CIs) to assess the relationships of predefined surgical variables and clinical prognosis. RESULTS: A total of 6361 adult patients from 41 studies were identified. Operative mortality was 38.2%. Pooled ORs showed increased odds of operative mortality in patients with preoperative or perioperative intraaortic balloon pump insertion (OR = 3.48; 95% CI, 3.01-4.02; P < .001), right ventricular dysfunction (OR = 2.85; 95% CI, 1.47-5.52; P = .002), posterior VSR (OR = 1.73; 95% CI, 1.30-2.31; P < .001), and emergency surgery (OR = 3.79; 95% CI, 2.52-5.72; P < .001). Temporal trend evaluation revealed no difference over time in the operative mortality rate; it was 34% in both time-related groups (1971-2000 versus 2001-2018). CONCLUSIONS: Ventricular septal rupture repair has a high operative mortality. Patients with preoperative or perioperative intraaortic balloon pump support, right ventricular dysfunction at presentation, or posterior defects, and those undergoing emergent VSR correction have increased odds of operative mortality.
