Association of Relative Left Ventricular Outflow Tract Area and Transcatheter Aortic Valve Replacement Related Paravalvular Leak.

ABSTRACT:

Background

Post-transcatheter aortic valve replacement (TAVR), paravalvular leak (PVL) is a quality metric associated with worse clinical outcomes. Transcatheter heart valve (THV) sizing is based primarily on the systolic annular size without regard to the left ventricular outflow tract (LVOT), which also lies within the THV landing zone. We hypothesized that LVOT size relative to the annulus is associated with post-TAVR PVL.

Methods

Data from consecutive patients undergoing TAVR in a single high-volume center from January 2018 to March 2019 were used. Pre-TAVR data from multidetector computed tomography (MDCT) were collected. Relative LVOT area was defined as LVOT area/annular area during systole. Logistic regression analysis was used to evaluate association with post-TAVR
