Ventricular Tachycardia Storm in a Patient with an Implanted Cardioverter-Defibrillator Following COVID-19 Infection.

Severe Coronavirus disease 2019 (COVID-19) infection presents with acute respiratory distress syndrome and multiorgan dysfunction. Cardiac involvement is seen in about a quarter of patients, and it can present as acute coronary syndromes, arrhythmias, myocarditis, and thromboembolic events. Ventricular arrhythmias in the setting of COVID-19 infection are usually multifactorial in etiology. There are only a few reports of ventricular tachycardia (VT) storms in patients with COVID-19 infection. We hereby report a case of an elderly man with severe left ventricular systolic dysfunction and a stable cardiac status for the last few years who, following coronary artery bypass graft surgery and implantable cardioverter-defibrillator (ICD) implantation, experienced a VT storm after a COVID-19 infection. The VT storm was controlled using multiple ICD shocks, along with antiarrhythmic drugs. Following his recovery from COVID-19 infection, the patient was asymptomatic at a 3-month follow-up.
