Is aortic valve replacement with the Medtronic Freestyle bioprosthesis safe and effective in patients requiring aortic valve replacement?
Aortic valve replacement with the Medtronic Freestyle bioprosthesis demonstrates acceptable safety and good hemodynamic performance, making it a viable option for older patients or those with a small aortic root.
Wang et al. (1999) conducted an observational in Aortic valve disease (n=85). Medtronic Freestyle bioprosthesis was evaluated on operative mortality. Aortic valve replacement with the Medtronic Freestyle bioprosthesis resulted in an operative mortality of 3.9% and good hemodynamic performance over a three-year follow-up.
