Bicuspid aortic stenosis treatment overview: Difference between revisions

Overview

Approximately 40% of patients with a bicuspid aortic valve potentially require aortic valve replacement in the third or fourth decade of their life.

Concomitant Disease of the Aorta

The aorta of patients with bicuspid aortic valve does not have the same histological characteristics of a normal aorta. The tensile strength is reduced. These patients are at a higher risk for aortic dissection and aneurysm formation of the ascending aorta. The size of the proximal aorta should be evaluated carefully during the evaluation of the patient for aortic stenosis surgery. The initial diameter of the aorta should be noted and periodic evaluation with CT scan (every year or sooner if there is a change in aortic diameter) should be recommended. Therefore, if the patient needs surgery, the size of the aorta will determine what type of surgery should be offered to the patient.

Associated Congential Heart Disease

Patients with bicuspid aortic valve are also at higher risk of aortic coarctation, an abnormal narrowing of the thoracic aorta ^[1].

-==Treatment and prognosis==
-Most patients with [[bicuspid aortic valve]] whose valve becomes dysfunctional will need careful follow-up and potentially valve replacement in their third or fourth decade of life.
-Patients with bicuspid aortic valve should be followed by cardiologist or cardiac surgeon with specific interest in this valve pathology.

-Another important fact is the aorta of patients with bicuspid aortic valve is not normal. The aorta of a patient with a bicuspid aortic valve does not have the same histological characteristics of a normal aorta. The tensile strength is reduced. These patients are at a higher risk for aortic dissection and aneurysm formation of the ascending aorta. The size of the proximal aorta should be evaluated careful during the work-up. The initial diameter of the aorta should be noted and periodic evaluation with CT scan (every year or sooner if there is a change in aortic diameter) should be recommended.
