Background: With improved durability of contemporary bioprostheses, surgeons are now recommending biologic valves in younger patients. However, long-term outcomes of patients younger than 60 years old undergoing biologic aortic valve implantation are not well known.

Methods: From November 1991 to March 2011, 144 patients less than 60 years old underwent aortic valve replacement (AVR) with Carpentier-Edwards pericardial valves (Edwards Lifesciences, Irvine, CA). Mean follow-up was 10±4 years. Outcomes were reported according to published guidelines.

Results: Seventy-five percent of patients were male, with a mean age of 51±9 years. Actuarial survival rates including early deaths were 89%±3%, 79%±4%, and 57%±6% after 5, 10, and 15 years of follow-up, respectively. Survival of patients was comparatively lower than a gender- and age-matched general population at all time points. The...
