What is aortic stenosis?

Answer 1

Aortic stenosis is a condition in which there is a narrowing of the opening of the aortic valve in the heart. This causes decreased blood flow from the heart. It can be a congenital heart defect, or it can occur later in life as the result of calcium deposit in this valve.

Answer 2

Aortic valve stenosis is a disease in which the opening to the aortic valve is narrowed, keeping blood from pumping well and increasing pressure the left ventricle. It leads to the walls of the left ventricle thickening in order to continue to pump blood. Eventually the left ventricle can become dilated, reducing the ability of the heart to pump blood.

The most common cause is age-related calcification of the aortic valve.

The symptoms of aortic stenosis are initially shortness of breath and later chest pain, loss of consciousness or heart failure.

Answer 3

subaortic and subvalvuar aortic stenosis is same thing

Rarely present at birth, late onset may be due to the presence of ther congenital defects. Left ventricular outflow tract (LVOT) narrowing takes three forms:
1. A discrete fibrous membrane located within 1 cm of the aortic valve.
2.A thick muscular ridge of collar.
3.Diffuse narrowind of the entire LVOT.
Patients with subvalvular stenosis present with dilated and tortuos coronary vessels and have an increased risk of coronary artery disease due to increased LV pressures that are generated past the areas of stenosis
