Abstract

Quadricuspid aortic valve (QAV) is an anatomic valvular variant, with a prevalence of 0.008% to 0.033% in the general population, and 1.46% in patients that undergo aortic valve replacement. The QAV can be an isolated valvular abnormality or associated with other congenital heart defects. In this article, we present three of the few reported cases of QAV in the Hispanic population, all of which were asymptomatic and without evidence of hemodynamic alterations or other associated heart defects. Additionally a literature review is provided.

摘要

四叶式主动脉瓣（QAV）是一种解剖学上的瓣膜变异，在普通人群中的患病率为0.008%至0.033%，在接受主动脉瓣置换术的患者中为1.46%。QAV可以是孤立的瓣膜异常，也可与其他先天性心脏缺陷相关。在本文中，我们介绍了少数几例西班牙裔人群中QAV的病例，所有病例均无症状，且无血流动力学改变或其他相关心脏缺陷的证据。此外，还提供了一篇文献综述。
