RESUMEN
Post-infarction mechanical complications include left ventricular free-wall rupture, ventricular septal rupture, and papillary muscle rupture. With the advent of early reperfusion strategies, including thrombolysis and percutaneous coronary intervention, these events now occur in fewer than 0.3% of patients following acute myocardial infarction. However, unfortunately, there has been no parallel decrease in associated mortality rates over the past two decades. Moreover, during the ongoing COVID-19 pandemic the incidence of mechanical complications resulting from ST-elevation myocardial infarction has possibly risen. Early diagnosis and prompt management are crucial to improving outcomes. Although some percutaneous device repair approaches are available, surgical treatment remains the gold standard for these catastrophic post-infarction complications. The timing of surgery, also related to the type of complication and patient's clinical conditions, and the possible role of mechanical circulatory supports before and after surgery, represent main topics of debate that still need to be fully addressed.
