In hypertrophic cardiomyopathy, which wall is typically more hypertrophic?

Explanation:
Hypertrophic cardiomyopathy most commonly shows asymmetric thickening of the interventricular septum. The septum thickens more than the left ventricular free wall, often in the basal region, which narrows the left ventricular outflow tract and can cause dynamic obstruction. This septal predominance is the hallmark pattern of HCM, setting it apart from conditions like hypertension where thickening is more uniform. The right ventricle and the right-sided septum aren’t the usual primary sites of hypertrophy in classic HCM, and isolated thickening of the left ventricular free wall is less typical. So, the left ventricular septum is the wall that’s typically more hypertrophic.
