supravalvulaarinen

Supravalvular is a medical term describing a location above a valve. In cardiovascular medicine, it commonly refers to supravalvular stenosis, a condition characterized by narrowing of the aorta just above the aortic valve. This obstruction can impede blood flow from the left ventricle to the rest of the body. Supravalvular aortic stenosis can be congenital, meaning it is present at birth, or acquired later in life. Congenital forms are often associated with genetic syndromes like Williams syndrome. Acquired forms can result from conditions such as vasculitis. Symptoms may vary depending on the severity of the stenosis and can include chest pain, shortness of breath, dizziness, and fatigue. Diagnosis typically involves imaging techniques like echocardiography, MRI, or CT scans, and sometimes cardiac catheterization. Treatment options range from medication to manage symptoms to surgical intervention to widen the narrowed area or replace the affected segment of the aorta.
