First Documentation of Persistent SARS-Cov-2 Infection Presenting With Late Acute Severe Myocarditis.Can J Cardiol. 2020 08; 36(8):1326.e5-1326.e7.CJ
A 64-year-old man presented with severe myocarditis 6 weeks after an initial almost asymptomatic severe acute respiratory syndrome coronavirus-2 (SARS-CoV2) infection. He was found to have a persistent positive swab. Mechanisms explaining myocardial injury in patients with COVID-19 remains unclear, but this case suggests that severe acute myocarditis can develop in the late phase of COVID-19 infection, even after a symptom-free interval.
