Survival and Long-term Outcomes Following Bioprosthetic vs Mechanical Aortic Valve Replacement in Patients Aged 50 to 69 Years

Abstract

Among propensity-matched patients aged 50 to 69 years who underwent aortic valve replacement with bioprosthetic compared with mechanical valves, there was no significant difference in 15-year survival or stroke. Patients in the bioprosthetic valve group had a greater likelihood of reoperation but a lower likelihood of major bleeding. These findings suggest that bioprosthetic valves may be a reasonable choice in patients aged 50 to 69 years.
