Abstract：
Aortic stenosis is one of the most prevalent cardiac valvular diseases throughout the world and has a significant impact on quality of life. While there are several etiologies, we will be discussing the case of a male in his mid-thirties of southeast Asian descent with a bicuspid aortic valve which was found to be functionally unicuspid and complicated by aortic dilation. Following a comprehensive review of literature, it appears this subset of aortic stenosis is not commonly encountered. In addition to presenting this fascinating case, we will review the epidemiology, classification and management of aortic stenosis. Furthermore, we will examine the latest evidence-based literature on bicuspid aortic valve and unicuspid aortic valve and discuss interventions and diagnostic tools that may improve clinical prognosis.
摘要：
主动脉瓣狭窄是世界上最常见的心脏瓣膜疾病之一，对生活质量有重大影响。虽然有几种病因，我们将讨论一个男性的案例，他在东南亚血统的30岁左右，患有二叶主动脉瓣，被发现是功能性单叶，并发主动脉扩张。在对文献进行全面回顾之后，这类主动脉瓣狭窄似乎并不常见.除了展示这个迷人的案例，我们将回顾流行病学，主动脉狭窄的分类和处理。此外，我们将研究有关二叶主动脉瓣和单叶主动脉瓣的最新循证文献,并讨论可能改善临床预后的干预措施和诊断工具.
