Longitudinal mixed effects models adjusted for age, gender, COPD, and baseline HRQoL

**

Positive values indicate better HRQoL with NRCA TA-TAVR, whereas negative values indicate worse HRQOL with NRCA TA—TAVR.

COPD = chronic obstructive pulmonary disease; EQ-5D = EuroQol 5D; HRQoL = health-related quality-of-life; KCCQ = Kansas City Cardiomyopathy Questionnaire; NRCA = non-randomized continued access registry; SAVR = surgical aortic valve replacement; SF-12 = Medical Outcomes Study Short-Form 12; TA = transapical; TAVR = transcatheter aortic valve replacement.
