bicuspid aortic valve
Congenital heart defect where the aortic valve has two leaflets instead of the normal three.
Full Definition
Bicuspid aortic valve is the most common congenital heart defect, occurring in 1-2% of the population, where the aortic valve is formed with only two cusps (leaflets) instead of the normal three. This malformation can lead to aortic stenosis, aortic regurgitation, or both, often requiring surgical intervention in adulthood. The condition is frequently associated with other cardiovascular abnormalities and requires careful documentation of valve morphology and function in medical records.
Usage
Usage note: Often abbreviated as BAV in clinical notes. Ensure distinction from bicuspid mitral valve.
