Introduction
Since the beginning of the SARS-Cov-2 pandemic, it was realized that cardiac involvement could occur, and elevated cardiac troponin I and the presence of angiotensin-converting enzyme 2 receptors (required for the entrance of the virus to cells) confirmed it. Moreover, mortality and morbidity were higher in patients with cardiovascular involvement [1, 2]. Cardiac involvement includes several manifestations such as acute myocardial injury, arrhythmia, myocarditis, cardiogenic shock, and heart failure in varying severities [3]. Nevertheless, the knowledge of the features of cardiac involvement and its mechanisms is scarce. Myocarditis is a rare complication in COVID-19, which contributes to rapid deterioration in patients.
Due to low incidence and failure to detect all cases with myocarditis, understanding the mechanism and management is not complete [4]. Herein, we presented eleven cases of COVID-19 who are clinically suspected to COVID-19 related myocarditis and their laboratory and echocardiographic findings besides their following-up in three months. Further prospective studies are necessary to recognize the underlying mechanism, manifestations, and management of myocarditis in COVID-19 patients.
