Key result
Aortic valve replacement with the Freestyle stentless bioprosthesis yielded an 80% overall survival rate at 5 years, with significant improvements in hemodynamics and left ventricular mass index.
Why the study?
Does aortic valve replacement with the Freestyle stentless bioprosthesis improve survival and hemodynamics in elderly patients requiring aortic valve replacement?
Cohort (n=95)
Does aortic valve replacement with the Freestyle stentless bioprosthesis improve survival and hemodynamics in elderly patients requiring aortic valve replacement?
The Freestyle stentless bioprosthesis provides safe midterm clinical outcomes and excellent hemodynamic performance, including regression of left ventricular hypertrophy, in elderly patients undergoing aortic valve replacement.
No takes yet. Share an insight, caveat, or question.
Supports safe midterm Freestyle stentless AVR in elderly patients; leaves open randomized comparisons to stented valves.
Yun et al. (1999) conducted a cohort in Aortic valve disease requiring replacement (n=95). Freestyle stentless bioprosthesis was evaluated on Overall actuarial survival rate at 5 years. Aortic valve replacement with the Freestyle stentless bioprosthesis yielded an 80% overall survival rate at 5 years, with significant improvements in hemodynamics and left ventricular mass index.
