AR = aortic regurgitation; AVA = aortic valve area; LV = left ventricular; N/A = not available; P = pressure; Vmax = maximum velocity.
↵∗ ΔLVEF compares the preoperative left ventricular ejection fraction (LVEF) with that at 3- to 6-month follow-up (a negative value indicates a decrease, whereas a positive indicates an increase in LVEF).
