Bicuspid aortic valve is the most common congenital cardiac malformation. Aortic valve replacement is often required in older patients but the surgical risk is often extremely high. As Transcatheter aortic valve implantation (TAVI) is an established therapy for intermediate and high surgical risk patients with symptomatic severe aortic valve stenosis (AS). Advances in technology and knowledge have led to TAVI being used for other pathologies and populations such as bicuspid AS. Recently, the diagnosis and classification of bicuspid aortic valve based on multidetector computed tomography (MDCT) assessment has been proposed, which may have an impact of outcomes after TAVI. This review article describes the advancements in diagnosis and outcomes of bicuspid AS.
二叶式主动脉瓣是最常见的先天性心脏畸形。老年患者常需要进行主动脉瓣置换,但手术风险往往极高。经导管主动脉瓣植入术(TAVI)是治疗有症状的重度主动脉瓣狭窄(AS)的中高危手术风险患者的既定疗法。技术和知识的进步已使TAVI用于其他病变和人群,如二叶式AS。最近,基于多排螺旋计算机断层扫描(MDCT)评估的二叶式主动脉瓣诊断和分类方法已被提出,这可能会对TAVI后的结局产生影响。这篇综述文章描述了二叶式AS在诊断和结局方面的进展。
