| 中文摘要: |
| 近年来，经导管主动脉瓣植入术（TAVI）为临床治疗外科手术禁忌的重度高危主动脉瓣狭窄提供了新的选择。治疗前全方位评估患者心脏和大血管的解剖有助于选择合适的TAVI手术方式、降低手术风险。MSCT具有高时间分辨率、高空间分辨率及单次即可完成大范围覆盖扫描等优点，可为TAVI提供更全面的信息。本文对MSCT在TAVI术前评估及术后随访中的应用予以综述。 |
| 英文摘要: |
| Over the past few years, transcatheter aortic valve implantation (TAVI) has developed into an alternative treatment for high-risk severe aortic stenosis patients without surgical operation. Comprehensive assessment of the heart and great vessels anatomy before operation is helpful to select the appropriate procedures and to reduce the risk of TAVI. MSCT has high temporal resolution, spatial resolution and wide range coverage of single scanning, which can provide more comprehensive information for TAVI. The application of MSCT in TAVI preprocedural planning and follow-up evaluation were reviewed in this article. |
