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.
正常发育的主动脉瓣有三个瓣叶。在主动脉瓣胚胎发育过程中，如果出现异常凹陷或融合，会导致瓣叶数量发生变化。二叶式主动脉瓣最为常见，但少见情况下也可见单叶式和四叶式主动脉瓣。本文报道了 2 例分别为 16 岁男性和 13 岁女性的单瓣叶单叶式主动脉瓣以及四叶式主动脉瓣病例。
