Index Case of COVID-19 Myocarditis Requiring BiV-ICD for Primary Prevention of Sudden Cardiac Death

Copyright© South Dakota State Medical Association..

INTRODUCTION: The severity of clinical presentation of COVID-19 myocarditis ranges from incidental identification of depressed left ventricular ejection fraction, cardiogenic shock requiring percutaneous mechanical circulatory support, to fatal fulminant myocarditis. In previously reported cases, surviving patients experienced improvement in left ventricular ejection fraction with the use of glucocorticoids and antivirals (+/- intravenous immunoglobulin/ convalescent plasma). We report the first case of COVID-myocarditis in a surviving patient where a persistently depressed left ventricular ejection fraction (less than 35 percent) despite optimal therapy prompted implantable cardioverter-defibrillator (ICD) implantation for primary prevention of sudden cardiac death.

CASE PRESENTATION: A previously healthy 67-year-old man, diagnosed with mild COVID-19 pneumonia five days prior, presented to the emergency department with suspected STEMI (hypoxia, substernal chest pain and known left bundle branch block). Left heart catheterization showed patent coronary arteries. Transthoracic echocardiogram showed severely depressed ejection fraction (15-20 percent). CT showed bilateral infiltrates: treatment was started with dexamethasone, remdesivir and convalescent plasma for acute hypoxic respiratory failure due to COVID-19 pneumonia. After a four-day hospitalization, guideline-directed medical therapy at maximum tolerated doses over three months did not improve left ventricular ejection fraction.

CONCLUSION: This is the index case of COVID-19 myocarditis-mediated heart failure with reduced ejection fraction requiring ICD for primary prevention of sudden cardiac death.
