Does echocardiographic investigation improve the presymptomatic diagnosis of cardiomyopathy in asymptomatic children with electrocardiographic T-wave inversion at preparticipation screening?
Echocardiographic investigation is warranted in children with postpubertal persistence of T-wave inversion to detect presymptomatic cardiomyopathy and prevent sudden cardiac death during sports.
The prevalence of T-wave inversion decreases significantly after puberty. Echocardiographic investigation of children with postpubertal persistence of T-wave inversion at preparticipation screening is warranted because it may lead to presymptomatic diagnosis of a cardiomyopathy that could lead to sudden cardiac death during sports.
Migliore et al. (2011) studied this question.
