What is it?
Hypertrophic cardiomyopathy is a disease characterized by hypertrophy limited to the LV, and often to the basal portion of the ventricular septum. The LV is not dilated unless there is a separate cause.
Hypertrophic cardiomyopathy is found in one in every 500 people. It’s the most common reason for sudden cardiac death (SCD) in young adults.
In hypertrophic cardiomyopathy, changes are the result of a genetic anomaly. Ventricular changes are usually asymmetrical, with hypertrophy predominantly affecting the ventricular septum. The increase in wall thickness may include the entire septum or just the basal septum. Often the septum increases to twice its normal size.
