Key result
Among patients receiving the Medtronic Freestyle bioprosthesis, operative risk was lowest with subcoronary implants (5.0%) and highest with root replacement (11.7%).

How do the clinical outcomes and operative risks compare among subcoronary, root inclusion, and complete aortic root replacement techniques using the Medtronic Freestyle bioprosthesis?
Absolute Event Rate: 5% vs 11.7%
The Medtronic Freestyle bioprosthesis is a versatile device for aortic valve replacement, with subcoronary implantation demonstrating lower operative risk and thromboembolism rates compared to root inclusion and complete root replacement.
Doty et al. (1998) conducted a cohort in Aortic valve disease requiring replacement (n=1,163). Medtronic Freestyle bioprosthesis implant techniques (subcoronary vs root inclusion vs root replacement) vs. Comparison between the three implant techniques was evaluated on Operative risk. Among patients receiving the Medtronic Freestyle bioprosthesis, operative risk was lowest with subcoronary implants (5.0%) and highest with root replacement (11.7%).
