Abstract

Exact and reliable measurements of anatomical dimensions in pre-procedural multi-slice computed tomography (MSCT) scans are crucial for optimal valve sizing and clinical results of transcatheter aortic valve replacement (TAVR). This study aimed to investigate interrater reliability between routinely used workflows for pre-procedural analysis. MSCT scans of 329 patients scheduled for TAVR were analyzed using both a 3mensio and SECTRA IDS7 platform. The results were retrospectively compared using the intraclass correlation coefficient, revealing excellent correlation in the analysis of simple diameters and poor correlation in the assessment of more complex structures with impact on calculated valve size.

摘要

在术前多层计算机断层扫描（MSCT）中精确可靠地测量解剖学尺寸对于经导管主动脉瓣置换术（TAVR）的最佳瓣膜尺寸确定和临床结果至关重要。本研究旨在调查术前分析常用工作流程之间的评分者间可靠性。使用3mensio和SECTRA IDS7平台对329例计划接受TAVR的患者的MSCT扫描进行分析。使用组内相关系数对结果进行回顾性比较，结果显示在简单直径分析中相关性极佳，而在对计算瓣膜尺寸有影响的更复杂结构评估中相关性较差。
