Time-Integrated Aortic Regurgitation Index Helps Guide Balloon Postdilation During Transcatheter Aortic Valve Replacement and Predicts Survival.

ABSTRACT: Background Balloon postdilation ( BPD ) has emerged as an effective strategy to reduce paravalvular regurgitation ( PVR ) during transcatheter aortic valve replacement ( TAVR ). We investigated the utility of a time-integrated aortic regurgitation index ( TIARI ) to guide balloon postdilation ( BPD ) after valve deployment. Methods and Results All consecutive patients who had echocardiography, aortography, and hemodynamic tracings recorded immediately after valve deployment during TAVR were included in the study. Catheter-derived invasive hemodynamic parameters were calculated offline. Among 157 patients who underwent TAVR , 49 (32%) patients required BPD to reduce significant PVR after valve deployment. Two experienced operators decided whether the patients required BPD for significant PV
