背景：我们研究了TAVI术后术中血管造影和超声心动图AR严重程度之间的关系，以及血管造影评估的临床稳健性。方法与结果：回顾性测量74例患者瓣旁反流血流的超声心动图周向范围（CE），并根据VARC-2切点进行分级；使用对比视频密度测量（VD）软件对tavi后血管造影AR进行回顾性量化，该软件计算左室流出道对比时间-密度积分与升主动脉对比时间-密度积分之比（LVOT-AR）。TAVI后立即超声心动图可分析74例，VD可分析主动脉造影51例。对51例超声心动图及VD进行评价。超声心动图AR分级的LVOT-AR中位数如下：无迹，0.07 (IQR, 0.05-0.11)；轻度，0.12 (IQR, 0.09-0.15)；中度，0.17 (IQR, 0.15 ~ 0.22
Background: We investigated the relationship between intraprocedural angiographic and echocardiographic AR severity after TAVI, and the clinical robustness of angiographic assessment.Methods and Results: In 74 consecutive patients, the echocardiographic circumferential extent (CE) of the paravalvular regurgitant jet was retrospectively measured and graded based on the VARC-2 cut-points; and angiographic post-TAVI AR was retrospectively quantified using contrast videodensitometry (VD) software that calculates the ratio of the contrast time-density integral in the LV outflow tract to that in the ascending aorta (LVOT-AR). Seventy-four echocardiograms immediately after TAVI were analyzable, while 51 aortograms were analyzable for VD. These 51 echocardiograms and VD were evaluated. Median LVOT-AR across the echocardiographic AR grades was as follows: none-trace, 0.07 (IQR, 0.05-0.11); mild, 0.12 (IQR, 0.09-0.15); and moderate, 0.17 (IQR, 0.15-0.22; P
