Population

103 patients (mean age 74 years) undergoing aortic valve replacement with the Medtronic Freestyle Bioprosthesis, followed for up to 2 years.

Exposure

Aortic valve replacement with the Medtronic Freestyle Bioprosthesis using a freehand subcoronary technique.

Outcome

Safety (mortality, thromboembolic events) and efficacy (transvalvular pressure gradient, effective valve orifice area by echocardiography)safety

Aortic valve replacement with the Medtronic Freestyle Bioprosthesis demonstrates low early mortality and good hemodynamic performance up to 2 years.

Doty et al. (2010) conducted a cohort in Aortic valve disease requiring replacement (n=103). Medtronic Freestyle Bioprosthesis was evaluated on safety and efficacy. Aortic valve replacement with the Medtronic Freestyle Bioprosthesis demonstrated a 3.9% 30-day mortality and 4.9% thromboembolic event rate, with good hemodynamic performance up to 2 years.
