With the introduction of transcatheter structural heart therapies, cardiologists are increasingly aware of the importance of understanding anatomical details of left-sided heart structures. Understanding fluoroscopic cardiac anatomy can facilitate optimal positioning and deployment of prostheses during transcatheter valve repair/replacement, left atrial appendage occlusion, septal defect closure, and paravalvular leak closure. It is possible to use multislice computed tomography to determine optimal fluoroscopic viewing angles for such transcatheter therapies. The purpose of this paper is to describe how optimal fluoroscopic viewing angles of left-sided heart structures can be obtained using computed tomography. Two- and 3-chamber views are described and may become standard in the context of transcatheter structural heart interventions.
随着经导管结构性心脏病治疗的引入，心脏病专家越来越意识到了解左心结构解剖细节的重要性。了解透视心脏解剖结构有助于在经导管瓣膜修复/置换、左心耳封堵、房间隔缺损封堵和瓣周漏封堵过程中优化假体的定位和部署。可以使用多层 CT 来确定此类经导管治疗的最佳透视观察角度。本文的目的是描述如何使用 CT 获得左心结构的最佳透视观察角度。本文描述了两腔和三腔视图，它们可能在经导管结构性心脏介入治疗中成为标准。
