Key result
The Carpentier-Edwards pericardial valve demonstrated excellent long-term durability in Japanese patients, with freedom from reoperation due to structural valve deterioration of 87.5% at 15 years.

Yes
Does aortic valve replacement with Carpentier-Edwards pericardial valves provide long-term durability in Japanese patients?
The Carpentier-Edwards pericardial bioprosthesis demonstrates excellent long-term durability in Japanese patients, particularly those aged ≥65 years, supporting current guideline recommendations for its use.
No takes yet. Share an insight, caveat, or question.
Supports durability in this Japanese cohort; leaves open need for randomized confirmation before broader practice change.
Minakata et al. (2014) conducted a cohort in Aortic valve disease requiring replacement (n=574). Carpentier-Edwards pericardial (CEP) valve was evaluated on Freedom from reoperation due to structural valve deterioration at 15 years. The Carpentier-Edwards pericardial valve demonstrated excellent long-term durability in Japanese patients, with freedom from reoperation due to structural valve deterioration of 87.5% at 15 years.
