Hypertrophic Cardiomyopathy

Also written as HCM.

Hypertrophic cardiomyopathy murmurs get louder with Valsalva and are less likely to radiate to the carotids.

Hypertrophic Cardiomyopathy (HCM)

Massive hypertrophy of left ventricle especially asymmetric septal hypertrophy
Small or normal cavity size; diastolic dysfunction (stiff ventricle, impaired filling)
Most common cause of sudden cardiac death in young athletes
Cause: Autosomal dominant mutations in sarcomere proteins (β-myosin heavy chain, troponin T, troponin I, myosin binding protein C)
Asymmetric septal hypertrophy
