Background— Prosthesis–patient size mismatch results when an implanted prosthetic aortic valve is of insufficient size for a patient’s body surface area. The relation between prosthesis–patient size and functional capacity and adverse postoperative outcome is inconsistent. Our objectives were to examine the impact of valve replacement, continuous prosthesis–patient size, and other factors on functional recovery after aortic valve replacement (AVR) with the Duke Activity Status Index (DASI).
