About oHCM Left Ventricular Outflow Tract (LVOT) • HCM causes the heart muscle to abnormally thicken. • In obstructive HCM (oHCM), the thickened muscle causes the left ventricle to become smaller, stiffer and less able to relax and fill with blood.1–4 • In oHCM, obstruction of the LVOT, blocks blood
