The bicuspid aortic valve (BAV) condition is characterized by prominent heterogeneity of its valvular phenotypic expression, of its associated disorders, its complications and its prognosis. Echocardiography serves as the first-line imaging modality in 5 major capacities: (1) BAV diagnosis, (2) valvular phenotyping, (3) assessment of valvular function, (4) measurement of the thoracic aorta and exclusion of aortic coarctation, and (5) assessment of uncommon but serious complications such as infective endocarditis and aortic dissection. This article presents a nosological perspective on the BAV condition, discusses the critical role of echocardiography as it relates to these 5 aforementioned capacities; and makes the case for a unified standard nomenclature for the BAV condition.
二叶式主动脉瓣（BAV）的特征在于其瓣膜表型表达、相关疾病、并发症和预后存在显著异质性。超声心动图在以下 5 个主要方面作为一线影像学检查手段：（1）BAV 的诊断，（2）瓣膜表型分析，（3）瓣膜功能评估，（4）胸主动脉的测量和排除主动脉缩窄，（5）评估感染性心内膜炎和主动脉夹层等罕见但严重的并发症。本文从分类学的角度介绍了 BAV 情况，讨论了超声心动图在这 5 个方面的关键作用，并提出了 BAV 条件的统一标准命名法。
