PURPOSE
The aim of our study was to evaluate the prevalence of early complications after Transcatheter Aortic Valve Implantation (TAVI) and their correlation with the Calcium Score (CS) of the aortic valve, aorta and ilio-femoral arteries derived from pre-procedural computed tomography (CT).
MATERIALS AND METHODS
We retrospectively reviewed 226 patients (100 males, mean age 79.4 ± 6.7 years) undergoing 64-slice CT for pre-TAVI evaluation from January 2018 to April 2021. The population was divided into CS quartiles.
RESULTS
Overall, 173 patients underwent TAVI procedure, of whom 61% presented paravalvular leak after the procedure, 28% presented bleeding or vascular complications, 25% presented atrioventricular block, and 8% developed acute kidney injury. The prevalence of paravalvular leak and vascular complications was higher in the upper CS quartiles for aortic valve and ilio-femoral arteries.
CONCLUSIONS
Aortic valve and vascular CS could help to predict post-TAVI early complications.
目的
本研究旨在评估经导管主动脉瓣植入术（TAVI）后早期并发症的发生率，并分析其与主动脉瓣、主动脉和髂股动脉的钙评分（CS）之间的相关性，这些 CS 值来自术前的 64 层 CT。
材料与方法
我们回顾性分析了 2018 年 1 月至 2021 年 4 月期间，226 例行 64 层 CT 检查的 TAVI 患者（100 名男性，平均年龄 79.4±6.7 岁）的资料。将患者分为 CS 四分位数组。
结果
共有 173 例患者接受了 TAVI 手术，其中 61%的患者术后出现瓣周漏，28%的患者出现出血或血管并发症，25%的患者出现房室传导阻滞，8%的患者发生急性肾损伤。主动脉瓣和髂股动脉 CS 较高的患者中，瓣周漏和血管并发症的发生率更高。
结论
主动脉瓣和血管 CS 可有助于预测 TAVI 术后早期并发症。
