Ventricular septal rupture and cardiogenic shock complicating STEMI during COVID-19 pandemic: An old foe re-emerges.

The COVID 19 pandemic resulted in a total reduction in the number of hospitalizations for acute coronary syndromes. A consequence of the delay in coronary revascularization has been the resurgence of structural complications of myocardial infarctions. Ventricular septal rupture (VSR) complicating late presenting acute myocardial infarction (AMI) is associated with high mortality despite advances in both surgical repair and perioperative management. Current data suggests a declining mortality with delay in VSR repair; however, these patients may develop cardiogenic shock while waiting for surgery. Available options are limited for patients with VSR who develop right ventricular failure and cardiogenic shock. The survival rate is very low in patients with cardiogenic shock undergoing surgical or percutaneous VSR repair. In this study we present two late presenting ST elevation MI patients who were complicated by rapidly declining hemodynamics and impending organ failure. Both patients were bridged with venoarterial extracorporeal membrane oxygenation (ECMO) to cardiac transplant.

The clinical spectrum of myocardial injury associated with COVID-19 infection.

Although respiratory symptoms are the dominant features of COVID-19 infection, myocardial injury has been described in these patients. Reported cardiac manifestations of COVID-19 infection include myocarditis, arrhythmia and acute coronary syndrome including ST elevation myocardial infarction (STEMI). STEMI is a medical emergency and timely intervention is of utmost importance to prevent mortality and long-term morbidities. In this report, we present a wide spectrum of clinical presentations, management, and outcomes for five patients with COVID-19 infection and ST elevation on ECG.
