Can echocardiographic and electrocardiographic evaluation distinguish children with hypertrophic cardiomyopathy at high risk of sudden death from those at low risk?
Echocardiography and electrocardiography can effectively risk-stratify children with hypertrophic cardiomyopathy to identify those at high risk of sudden death.
Children at high risk of dying suddenly with hypertrophic cardiomyopathy, with a subsequent annual mortality of 6.6%, can be distinguished at the time of diagnosis from those patients having a low risk of sudden death, the latter with an annual mortality of 0.27%.
Östman‐Smith et al. (Fri,) studied this question.
