Sudden cardiac arrest in a young patient with hypertrophic cardiomyopathy and zero canonical risk factors: the inherent limitations of risk stratification in hypertrophic cardiomyopathy

Congenit Heart Dis. 2014 Mar-Apr;9(2):E51-7. doi: 10.1111/chd.12073. Epub 2013 May 7.

Abstract

Hypertrophic cardiomyopathy is the most common heritable cardiovascular disease and a common cause of sudden cardiac death (SCD) in young adolescents and athletes. Clinical risk stratification for SCD is predicated on the presence of established risk factors; however, this assessment is far from perfect. Herein, we present a 16-year-old male who was resuscitated successfully from his sentinel event of out-of-hospital cardiac arrest. Prior to this event, he was asymptomatic and lacked all traditional SCD-predisposing risk factors for hypertrophic cardiomyopathy.

Keywords: HCM; ICD; Risk Factor; Risk Stratification; Sudden Cardiac Death.
