Aortic stenosis is a common disorder that affects nearly 5% of persons >75 years of age. Aortic valve replacement is indicated for symptomatic patients with severe aortic stenosis, as the prognosis of untreated patients is poor. Nevertheless, many patients with symptomatic severe aortic stenosis do not undergo surgical valve replacement, which has been attributed to comorbidities. Transcatheter aortic valve implantation (TAVI) is a novel method to treat selected high-risk patients with aortic stenosis. Patient screening and anatomic measurements of the aortic root are of great importance to ensure procedural success and appropriate patient selection. This review outlines comprehensive multidisciplinary assessment and selection of these patients and the evolving role of the echocardiogram and the multislice computed tomography in support of TAVI program.
主动脉瓣狭窄是一种常见疾病，影响着近5%的75岁以上人群。对于有症状的重度主动脉瓣狭窄患者，建议进行主动脉瓣置换，因为未经治疗的患者预后较差。然而，许多有症状的重度主动脉瓣狭窄患者并未接受外科瓣膜置换，这被认为是由合并症导致的。经导管主动脉瓣植入术（TAVI）是治疗特定高危主动脉瓣狭窄患者的一种新方法。对主动脉根部进行患者筛查和解剖测量对于确保手术成功及合理选择患者至关重要。本综述概述了对这些患者进行的全面多学科评估与选择，以及超声心动图和多层计算机断层扫描在支持TAVI项目中不断演变的作用。
