APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -What is atherosclerosis? Atherosclerosis thickening or hardening of the arteries. It is caused by a buildup of plaque in the inner lining of an artery. Plaque is made up of deposits of fatty substances, cholesterol, cellular waste products, calcium, and fibrin.

Detailed explanation-2: -Thickening of the heart muscle (myocardium) The thickened septum may cause a narrowing that can block or reduce the blood flow from the left ventricle to the aorta-a condition called outflow tract obstruction. The ventricles must pump harder to overcome the narrowing or blockage.

Detailed explanation-3: -Alcohol septal ablation (nonsurgical procedure): Ethanol (a type of alcohol) is injected through a tube into the small artery that supplies blood to the area of heart muscle thickened by hypertrophic cardiomyopathy. The alcohol causes these cells to die. The thickened tissue shrinks to a more normal size.

Detailed explanation-4: -Normal thickness is 10 millimeters or less, but HCM occurs when the heart wall thickening is 13 to 15 millimeters. “When the ventricular wall gets to three centimeters or more, that’s very concerning as it increases your risk for a dangerous heart rhythm that can lead to sudden death, ‘’ Wever-Pinzon says.
