Abstract
The aim of this study was to compare the hemodynamic characteristics and early clinical results of a commercially available standard aortic conduit with those of a modified valved composite graft, which consists of a mechanical valve prosthesis sewn into a vascular tube and placed in a supraannular position. The modified conduit was placed in 40 patients (group 1) and the standard conduit in another 40 patients (group 2). The early postoperative mortality rates (within 30 days after surgery) were 0% in group 1 and 5% (2 patients) in group 2; the difference was not statistically significant. The mean geometric orifice area of the valve prosthesis was significantly larger in group 1 than in group 2 (3.7 ± 0.7 cm2 versus 2.9 ± 0.5 cm2). Early results showed a hemodynamic advantage of the modified conduit, with significantly lower transvalvular gradients.
