Sudden death of an athlete due to concealed arrhythmogenic cardiomyopathy: Why preparticipation screening did fail

: We report the case of a professional soccer athlete who died suddenly for arrhythmogenic cardiomyopathy that was not diagnosed at the time of preparticipation screening. Exercise testing had repeatedly shown effort-induced premature ventricular beats with normal echocardiography, which was considered reassuring. However, there is emerging evidence that cardiac diseases characterized by focal ventricular scarring may not cause wall motion abnormalities and can be revealed only by tissue characterization with cardiac magnetic resonance. Modern interpretation of premature ventricular beats features is essential to select athletes who should undergo advanced cardiac imaging investigations, to achieve a correct diagnosis and allow safe sport participation.
