Why the study?

Do Medtronic Intact bioprostheses provide similar hemodynamic performance compared to bileaflet mechanical valves in the aortic position?

Structured PICO

Do Medtronic Intact bioprostheses provide similar hemodynamic performance compared to bileaflet mechanical valves in the aortic position?

Population

112 patients with either Medtronic Intact bioprostheses (n=45) or bileaflet mechanical valves (n=67) in the aortic position

Intervention

Medtronic Intact bioprostheses in the aortic position

Comparator

Bileaflet mechanical valves in the aortic position

Outcome

Hemodynamic performances (transvalvular pressure gradients) determined by Doppler echocardiographysurrogate

Medtronic Intact bioprostheses and bileaflet mechanical valves in the aortic position demonstrate similar hemodynamic characteristics when matched for annulus size.
