Bicuspid aortic valve (BAV) is a condition characterized by the abnormal development of the aortic valve. As the name suggests, instead of the usual three cusps, patients with BAV have only two cusps in their aortic valve, which can lead to a number of problems in the heart. There are several synonyms used to describe this condition, including bicuspid valve disease, bicuspid aortic stenosis, and bicuspid aortic valve disease. Symptoms of BAV may include chest pain, shortness of breath, and an irregular heartbeat. If left untreated, it can lead to serious complications such as heart failure, stroke, and aortic aneurysm.
