This brings serious clinical concerns regarding the potential need for in\u2010depth cardiac screening in athletes after Covid\u201019 before return to play. The aim of this study was to gain further insight into the relation between Covid\u201019 and cardiac involvement in professional athletes. This was a retrospective cohort study, in which 26 consecutive elite athletes (national team, Olympians, top national league players; median age 24\u2009years, interquartile range [IQR] 21\u201327, 81% female) were included. At 1.5\u00a0T including balanced steady\u2010state free precession cine imaging, T1 and T2\u2010mapping using Myomaps software (Siemens), dark\u2010blood T2\u2010weighted images with fat suppression, and late gadolinium enhancement (LGE) with phase\u2010sensitive inversion recovery sequence were used. The athletes had mainly asymptomatic or mild course of the disease (77%). They were scanned after a median of 32\u2009days (IQR 22\u201362\u2009days) from the diagnosis. MR data were reviewed by three independent observers, each with &gt;10\u2009years cardiac MR experience. Native T1, T2, extracellular volume, and T2 signal intensity ratio were calculated. Diagnosis of acute myocarditis was based on modified Lake Louise criteria. Statistical analyses used were Pearson correlation and Bland\u2013Altman repeatability analysis. At the time of MR the athletes had no pathologic electrocardiogram abnormalities or elevated troponin levels. MR did not reveal any case of acute myocarditis. Cardiac abnormalities were found in five (19%) athletes, including four athletes presenting borderline signs of isolated myocardial edema and one athlete showing nonischemic LGE with pleural and pericardial effusion. Another athlete had signs of persistent lung congestion without cardiac involvement. We have shown that in a small group of elite athletes with mainly asymptomatic to mild Covid\u201019, lack of electrocardiographic changes, and normal troponin concentration 1\u20132\u00a0months after the diagnosis, there were no signs of acute myocarditis, but 19% of athletes had some abnormalities as assessed by cardiac MR.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of
