Incidental diagnosis of apical hypertrophic cardiomyopathy with aneurysm in an athleteHypertrophic cardiomyopathy (HCM), defined by the presence of increased left ventricular (LV) wall thickness that is not solely explained by abnormal loading conditions (hypertension, valve disease, etc.) , is the leading cause of sudden cardiac death (SCD) in young competitive athletes . HCM expression is highly variable, with asymmetrical septal hypertrophy being the most common variant and accounting for approximately 80% of cases. Still, about 10% of HCM patients present with apical HCM  and about 5% of HCM patients show an apical aneurysm defined as a thin-walled dyskinetic or akinetic segment of the most distal portion of the LV chamber .
