Atypical presentation of COVID-19 as subclinical myocarditis with persistent high-degree atrioventricular block treated with pacemaker implant

Abstract

The novel coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a positive-sense, single-stranded RNA virus.1 The most common presenting symptoms include cough, fever, fatigue, shortness of breath, sore throat, and headache. Although respiratory failure is the primary complication seen in COVID-19, patients are at high risk of having multisystem involvement, including acute cardiac injury.2 We present an atypical case of COVID-19 infection with subclinical myocarditis and intermittent complete atrioventricular (AV) block to demonstrate the value of cardiac magnetic resonance imaging (cMRI) in detecting early cardiac involvement.
