Clinical outcomes are reported as 5-year Kaplan–Meier event rates, including 95% CI. Hemodynamic performance is presented either as mean ± SD or median (interquartile range). PVL, Paravalvular leak; NA, not available; EOA, effective orifice area; EOAi, effective orifice area indexed according to body surface area.
P value from log rank test for all clinical outcomes and from independent samples t test, Mann–Whitney U test, or χ2 test for echocardiographic data.
