Abstract
In patients with aortic stenosis undergoing transcatheter aortic valve replacement
(TAVR), studies have suggested that reduced left ventricular (LV) ejection fraction
(LVEF) and low aortic valve gradient (AVG) are associated with worse long-term outcomes.
Because these conditions commonly coexist, the extent to which they are independently
associated with outcomes after TAVR is unknown.
