Aortic Stenosis

Aortic stenosis is a narrowing of the aortic valve, the valve that allows blood to flow from the heart's lower left chamber into the aorta and to the entire body. The narrowing prevents the valve from opening properly, forcing the heart to work harder. This causes pressure to build up in the lower left chamber of the heart, thickening the heart muscle. The pressure can lead to chest pain, blood backup into the lungs, and severe forms of the condition can prevent enough blood from reaching the brain and the rest of the body. Eventually, the pressure can lead to heart failure, fatigue and dizziness. Aortic stenosis can occur when calcium builds up on the valve over several years, making it thick and hard. It also can be caused by a heart defect or infections of the heart that can damage the valve. Aortic stenosis is not common and affects more men than women. It can occur in children less frequently. Severe cases often require surgery.



With the first and largest comprehensive heart valve program in the state, UAB Medicine provides continuing care for patients who have or are at risk for valve disease. Our team of surgeons and cardiologists are among the nation’s most highly regarded physicians, and they provide a multidisciplinary approach to the diagnosis and treatment of valve disease. From aortic valve stenosis to mitral valve regurgitation, and from traditional open-heart surgery to the latest in minimally invasive procedures and robotic-assisted valve repair surgery, UAB patients benefit from our expertise in treating patients with valve disease.

The UAB Comprehensive Valve Program has built an impressive list of accomplishments in recent years. Our cardiologists and heart surgeons performed the first transcatheter aortic valve replacement (TAVR) in Alabama; to date UAB has performed more TAVRs than any other hospital in the state. As an added service, patients who have been told by non-UAB doctors that they need valve surgery can speak to a UAB valve surgeon for a second opinion.
