^†Crude/unadjusted hazard ratios estimated for aortic valve calcium score category (high vs. low)

^‡Propensity score adjusted hazard ratios estimated for aortic valve calcium score category (high vs. low)

Propensity score included age, pre-TAVR peak aortic valve velocity, pre-TAVR calculated valve area, pre-TAVR stroke volume index, pre-TAVR LVEF, pacemaker implantation, LBBB, Charlson comorbidity index, STS predicted risk of surgical mortality, TAVR access type, valve type, procedure site and post-TAVR peri-valvular leak.

LBBB – Left bundle branch block; LVEF – Left ventricular ejection fraction; TAVR – Transcatheter aortic valve replacement; STS – Society for thoracic surgeons
