Temporal trends of longitudinal measures after 4 aortic root procedures for aneurysms. Solid lines represent unadjusted estimates of temporal trend, and symbols represent data grouped (without regard to repeated measurements) within a timeframe to provide a crude verification of model fit. A, Mean aortic valve gradient; (B) Grade 3+/4 + postoperative AR. Only 1 mechanical composite valve developed severe regurgitation. C, LV mass index. AR, Aortic valve regurgitation; LV, left ventricular. Red triangles = composite graft replacement with biologic valve; purple squares = composite graft replacement with mechanical valve; blue circles = valve preservation; and brown diamonds = allograft root and ascending aorta replacement with coronary reimplantation.
