This thickening may result in elevation of pressure within the heart and sometimes poor pumping action. The goal of hypertrophic cardiomyopathy treatment is to relieve symptoms and prevent sudden cardiac death in people at high risk. Hypertrophic cardiomyopathy typically affects the muscular wall (septum) between the two bottom chambers of the heart (ventricles). 2. 2. It is clinically important to distinguish between the obstructive and nonobstructive forms of hypertrophic cardiomyopathy, on the basis of the presence or absence of a gradient between the left ventricular outflow tract (LVOT) and the aorta with the patient at rest and/or with provocation 2.

Asymmetric septal hypertrophy - a marker of hypertension in aortic stenosis (a SEAS substudy) Hypertension is the main clinic characteristic of ASH and asymmetric LV hypertrophy in patients with asymptomatic aortic stenosis independent of severity of aortic stenosis.
