IMPACT OF LEFT VENTRICULAR OUTFLOW TRACT (LVOT) MORPHOLOGY AND LVOT-ANNULAR MISMATCH ON PARAVALVULAR LEAK AND NEW CONDUCTION ABNORMALITIES AFTER TRANSCATHETER AORTIC VALVE REPLACEMENT: CONCEPT OF THE “NON-TUBULAR INDEX” AND LVOT SEAL ZONE

IMPACT OF LEFT VENTRICULAR OUTFLOW TRACT (LVOT) MORPHOLOGY AND LVOT-ANNULAR MISMATCH ON PARAVALVULAR LEAK AND NEW CONDUCTION ABNORMALITIES AFTER TRANSCATHETER AORTIC VALVE REPLACEMENT: CONCEPT OF THE “NON-TUBULAR INDEX” AND LVOT SEAL ZONE

Background We conceptualize a seal zone at and below the annulus to quantify LVOT-Annular mismatch and derive a “non-tubular index (NTI)”, to determine the impact of LVOT anatomy on TAVR outcomes. In CV patients (n=109), there were no differences in mean NTIs between the PVL groups (p=0.65) and betw...

Zusammenfassung:Background We conceptualize a seal zone at and below the annulus to quantify LVOT-Annular mismatch and derive a “non-tubular index (NTI)”, to determine the impact of LVOT anatomy on TAVR outcomes. In CV patients (n=109), there were no differences in mean NTIs between the PVL groups (p=0.65) and between no LBBB and pLBBB groups (p=0.65).
