Left ventricular noncompaction (LVNC) is a rare form of cardiomyopathy due to abnormal morphogenesis of the endocardium and myocardium that occurs in early stages of foetal life. Given the increased risk of sudden cardiac death associated with LVNC, athletes with this diagnosis should be excluded from most competitive sports with the possible exception of those of low intensity (class IA) in selected cases. We report de novo diagnosed LVNC in an asymptomatic young footballer. JRCD 2014; 1 (7): 21–23
