Hypertrophic Cardiomyopathy (HCM) is characterized by abnormal thickening of the heart muscle, most often in the interventricular septum, which divides the left and right ventricles. This thickening can disrupt normal heart function by narrowing the left ventricle, making it more difficult for blood to flow into the aorta through the aortic semilunar valve. In obstructive HCM, the thickened septum can bulge into the left ventricular outflow tract, which is the pathway through which blood flows from the left ventricle to the aorta. When the septum blocks this passage, it increases pressure inside the heart, making it harder for blood to be pumped to through the systemic system. With this lack of nutrient and oxygen exchange at the capillary beds, biological functions can fail. The human body can go into organ failure if the kidneys do not receive five liters of blood.
To combat hypertrophic cardiomyopathy a septal myectomy can be preformed. This is a surgical procedure designed to remove a portion of the interventricular septum muscle. By removing the thickened tissue, the surgery effectively relieves the obstruction. This restoration of normal outflow reduces the pressure within the heart, alleviating symptoms. Which also allows for systemic blood flow, and for the kidney's to receive their required five liters. Septal myectomy can improve long-term heart function and quality of life for patients with obstructive HCM.
