Fig 1 Postoperative transprosthesis gradients in patients with small aortic roots who underwent aortic valve replacement (AVR [shaded bars]) or AVR plus aortic root enlargement (ARE [open bars]). Both mean and peak transprosthetic gradients were significantly lower in the AVR plus ARE group.

Fig 2 (A) Survival and (B) freedom from New York Heart Association class III or IV congestive heart failure (CHF) or CHF death among patients with small aortic roots who underwent aortic valve replacement (AVR [dotted line]) or AVR plus aortic root enlargement (ARE [solid line]). After adjusting for potential confounders in the multivariate analysis, an ARE was associated with a trend toward better long-term freedom from CHF (p = 0.19) but not long-term survival (p = 0.81).
