Aortic stenosis (AS) is the most common primary valve disorder in the elderly with an increasing prevalence; transcatheter aortic valve implantation (TAVI) has become an accepted alternative to surgical aortic valve replacement (AVR) in the high risk or inoperable patient. Appropriate selection of patients for TAVI is crucial and requires a multidisciplinary approach including cardiothoracic surgeons, interventional cardiologists, anaesthetists, imaging experts and specialist nurses. Multimodality imaging including echocardiography, CT and MRI plays a pivotal role in the selection and planning process; however, echocardiography remains the primary imaging modality used for patient selection, intra-procedural guidance, post-procedural assessment and long-term follow-up. The contribution that contemporary transthoracic and transoesophageal echocardiography make to the selection and planning of TAVI is described in this article.
主动脉瓣狭窄（AS）是老年人中最常见的原发性瓣膜疾病，其患病率呈上升趋势；经导管主动脉瓣植入术（TAVI）已成为高危或无法手术患者接受外科主动脉瓣置换术（AVR）的一种可接受的替代方案。为TAVI适当选择患者至关重要，需要多学科方法，包括心胸外科医生、介入心脏病学家、麻醉师、影像专家和专科护士。包括超声心动图、CT和MRI在内的多模态成像在选择和规划过程中起着关键作用；然而，超声心动图仍然是用于患者选择、术中指导、术后评估和长期随访的主要成像方式。本文描述了当代经胸和经食管超声心动图对TAVI选择和规划的贡献。
