Asymmetric involvement of the interventricular septum is the most common hypertrophic cardiomyopathy and other variants include apical, symmetric, midventricular, masslike, and noncontiguous hypertrophic cardiomyopathy (Figure 2) 4. The thickened heart muscle makes it harder for the heart to pump blood and makes the heart prone to a rare but serious rhythm dysfunction. This makes it hard for the heart to relax and reduces the amount of blood the ventricle can hold and send to the body with each heartbeat. AJR Am J Roentgenol. As a result, blood pressure in the heart increases. These patients had higher systolic blood pressure, lower LV ejection fraction and larger left atrial diameter than patients with ASH only.
