Abstract:In patients aged <65 years, despite an increase in the rate of reoperation with stented bioprosthetic valves and an increase in major bleeding events with mechanical valves, there is no significant difference in mortality at late follow-up.
“…Some previous studies found that patients in this age group who received a mechanical valve had a better survival [8,9] whereas others did not find a survival difference between patients with a mechanical valve and a bioprosthesis [10,11].…”

“…T he use of bioprostheses has considerably increased in the past decade and has led to a substantial reduction of mechanical valve implantations [1]. This trend may be explained by an increasing number of studies reporting improved long-term durability of more recent tissue valve models [2]. Nevertheless, biologic aortic valve replacement (AVR) in patients younger than 60 years remains controversial, and the expected event rates for surgical and valve-related complications have not been clearly determined in this patient subset.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
