ST-elevation myocardial infarction treatment in the modern era has focused on minimizing time of ischemia by reducing door-to-balloon time to limit infarct size and improve survival. Although there have been significant improvements in minimizing time to coronary reperfusion, the incidence of heart failure following a myocardial infarction has remained high. Preclinical studies have shown that unloading the left ventricle for 30 min prior to coronary reperfusion can reduce infarct size and promote myocardial recovery. The DTU-STEMI randomized prospective trial will test the hypothesis that left ventricular unloading for at least 30 min prior to coronary reperfusion will improve infarct size and heart failure-related events as compared with the current standard of care.Lay abstract Improvements in the treatment of heart attacks over the years have focused on rapidly opening the blocked vessel to limit the amount of heart muscle damage. Although there have been significant improvements in minimizing the time to treatment using various options from medications to balloons and stents, there continues to be a high incidence of heart failure following a heart attack with larger heart attacks leading to more heart failure. Recent studies in animal models have shown that unloading the work of the heart with a temporary heart pump can decrease the size of the heart attack and improve heart muscle recovery. The door-to-unload research program continues to investigate the treatment strategy of unloading the heart for at least 30 min prior to opening the blocked vessel to improve patient outcomes.

Ventricular septal rupture (VSR) following myocardial infarction is rare in the reperfusion era. The decrease in patients presenting with myocardial infarction during the coronavirus-2019 (COVID-19) pandemic could result in more frequent VSR. This report describes two patients with VSR presenting late after myocardial infarction and treated at a single institution.
