Key result
Two rare cases of abnormal aortic valve development were reported: a 16-year-old male with a unicommissural unicuspid aortic valve and a 13-year-old female with a quadricuspid aortic valve.
Why the study?
Unicuspid and quadricuspid aortic valves are rare congenital anomalies resulting from abnormal embryological excavation or fusion of aortic valve cusps.

Highlights rare congenital anomalies of the aortic valve, specifically unicuspid and quadricuspid variants, which are less common than bicuspid aortic valves.
There are three cusps in a normally developed aortic valve. Abnormal excavation or fusion, during the embryological development of the aortic valve, results in a varying number of cusps. Bicuspid aortic valve is the most common, but more rarely, unicuspid and quadricuspid aortic valves can be seen.Here, a case of a 16-year-old male with a unicommissural unicuspid aortic valve and a case of a 13-year-old female with a quadricuspid aortic valve were reported.

Eyüp Aslan (2021) conducted a case report in Unicuspid and quadricuspid aortic valves (n=2). Unicuspid and quadricuspid aortic valves was evaluated. Two rare cases of abnormal aortic valve development were reported: a 16-year-old male with a unicommissural unicuspid aortic valve and a 13-year-old female with a quadricuspid aortic valve.
