Aortic Stenosis: Symptoms & Signs

Medically Reviewed on 9/10/2019

Aortic stenosis is a disease in which the opening of the aortic valve of the heart (which allows blood to pass from the left ventricle out to the main artery of the body, the aorta) is abnormally narrowed. This impairs the delivery of oxygen-carrying blood to the body.

Signs and symptoms of aortic stenosis are due to heart failure and include chest pain, shortness of breath, and lightheadedness or fainting. A heart murmur may be present on examination of the chest with a stethoscope. Other associated symptoms can include fatigue, inability to exercise, and abnormal heart rhythms (arrhythmias).

Cause of aortic stenosis

Congenital abnormalities of the aortic valve, scarring of the aortic valve as occurs in some people after rheumatic fever, and wear and tear of the aortic valve in the elderly can cause aortic stenosis.
