Abstract: Objectives: We used a modified technique of a composite graft by moving the valve prosthesis away from the end into the inside of the tube and compared the effectiveness of this surgical method with the standard valved conduits.<br />Methods: Through a prospective nonrandomized clinical study between March 2011 and June 2012, we performed replacement of the aortic valve and ascending aorta in 30 consecutive patients using a valved composite graft with a mechanical valve prosthesis. A modified self-assembled valved composite graft was employed in 20 patients (Modified group), while the remaining 10 patients received the standard composite graft (Control group).<br />Results: There was significantly less bleeding in the patients with modified grafts (184 vs. 415 mL, p < 0.05). Moreover, the mean transvalvular gradient of the composite graft patients was lower in the modified group than in the control group (9 vs. 14 mmHg, respectively, p < 0.05).<br />Conclusions: The modified valve composite graft technique results in good hemodynamics and appears to limit blood loss.<br /> (© 2014 Wiley Periodicals, Inc.)
