Abstract: Annular sizing predicts paravalvular leak (PVL) and new persistent left bundle branch block (pLBBB), but little is known on Left Ventricular Outflow Tract (LVOT) anatomy on TAVR outcomes. We propse an LVOT seal zone to quantify LVOT-Annular mismatch and derive a “non-tubular index (NTI)”, to
