SARS-CoV-2 viral particles have been identified by real-time polymerase chain reaction (PCR) testing in cardiac tissue, providing evidence that direct cardiotoxicity might occur. Since more than 7.5% of myocardial cells have positive ACE2 expression, this could mediate SARS-CoV-2 entry into cardiomyocytes and cause direct cardiotoxicity. The CMR study performed on a 1.5T system (Magnetom Aera, Siemens Healthineers, Erlangen, Germany) showed normal biventricular function, no regional wall motion abnormalities, slightly increased T2 (54 ms, normal < 52 ms) and native T1 values (1110 ms, CMR allows targeting of several features of myocarditis, such as contractile dysfunction, inflammatory edema, and necrosis, and has become the gold standard for the noninvasive assessment of the disease.
