Outcomes and hemodynamics after aortic valve replacement: a comparison of stentless versus mechanical valves.

Purpose: Some investigators suggest that hemodynamic outcomes may be superior with the stentless aortic bioprosthesis when compared with a mechanical valve. The goal of this study was to characterize outcomes and hemodynamic data associated with each type of valve.

Subjects And Methods: Patient outcomes and echocardiographic data were compared between 25 patients with stentless valves and 59 patients with mechanical valves.
