BackgroundLeft ventricular free‐wall rupture (LVFWR) is one of the most lethal complications after acute myocardial infarction (AMI). The optimal therapeutic strategy is controversial. The current meta‐analysis sought to examine the outcome of patients surgically treated for post‐AMI LVFWR.MethodsA comprehensive literature review was performed to identify articles reporting outcomes of subjects who underwent LVFWR surgical repair. The primary endpoint was operative mortality. A meta‐analysis was performed to assess the associations of predefined variables of interest and clinical prognosis.ResultsOf the 3132 retrieved articles, 11 nonrandomized studies, enrolling a total of 363 patients, fulfilled the inclusion criteria and were included in this analysis. The mean age of patients was 68 years. The operative mortality rate was 32% (n = 115). Meta‐analysis revealed reduced operative risk in patients with oozing type rupture, as compared to blowout type (risk ratios [RR]: 0.47; 95% confidence interval [CI]: 0.33–0.67; p < .0001); RR was also significantly reduced in subjects in whom LVFWR was treated with sutureless technique, as compared to those undergoing sutured repair (RR: 0.59; 95% CI: 0.41–0.83; p = .002). Increased risk of operative mortality was demonstrated in patients who required postoperative extracorporeal membrane oxygenation (ECMO) support (RR: 2.39; 95% CI: 1.59–3.60; p < .0001).ConclusionsSurgical treatment of postinfarction LVFWR has a high operative mortality rate. Blowout rupture, sutured repair and postoperative ECMO support are factors associated with increased risk of operative mortality.
