During the last decade, the development of transcatheter based therapies has provided feasible therapeutic options for patients with symptomatic severe valvular heart disease who are deemed inoperable. The promising results of many nonrandomized series and recent landmark trials have increased the number of percutaneous transcatheter valve procedures in high operative risk patients. Pre-procedural imaging of the anatomy of the aortic or mitral valve and their spatial relationships is crucial to select the most appropriate device or prosthesis and to plan the percutaneous procedure. Multidetector row computed tomography provides 3-dimensional volumetric data sets allowing unlimited plane reconstructions and plays an important role in pre-procedural screening and procedural planning. This review will describe the evolving role of multidetector row computed tomography in patient selection and strategy planning of transcatheter aortic and mitral valve procedures.
在过去的十年中，基于经导管的治疗方法的发展为那些被认为无法手术的有症状的严重瓣膜性心脏病患者提供了可行的治疗选择。许多非随机系列和最近的里程碑试验的有希望的结果增加了经皮经导管瓣膜手术在高手术风险患者中的数量。主动脉瓣或二尖瓣解剖结构及其空间关系的术前成像对于选择最合适的器械或假体以及规划经皮手术至关重要。多排螺旋 CT 提供了 3 维容积数据集，允许进行无限的平面重建，并且在术前筛选和手术规划中发挥着重要作用。这篇综述将描述多排螺旋 CT 在经导管主动脉瓣和二尖瓣手术患者选择和策略规划中的作用演变。
