Abstract

Sudden cardiac death (SCD) is an uncommon but devastating potential consequence of participation in competitive sport. It is seen in adolescent and young adult athletes. The most common cause of this, hypertrophic cardiomyopathy (HCM), is a genetic disorder responsible for more than a third of cases and is manageable. Screening is undertaken for HCM, using differing strategies in Europe and North America. Screening and early diagnosis have reduced the mortality rate but has come at a significant economic cost. The evidence and relevant arguments for and against screening are presented together with management strategies as reflected by an illustrative case.
