Key result
Antibiotic-sterilised homograft aortic valve replacement yielded a 20-year survival of 55.0% and freedom from structural degeneration of 41.9%, with higher failure risk in younger patients.
Why the study?
Does antibiotic-sterilised homograft aortic valve replacement provide good long-term survival and freedom from structural degeneration in patients requiring AVR?

Does antibiotic-sterilised homograft aortic valve replacement provide good long-term survival and freedom from structural degeneration in patients requiring AVR?
Antibiotic-sterilised homograft aortic valve replacement offers good long-term results, though the risk of valve failure is significantly higher in younger patients and those undergoing aortic root tailoring.
No takes yet. Share an insight, caveat, or question.
Warrants caution with homograft AVR in younger patients; extends observational evidence on long-term durability.
Langley et al. (1996) conducted a cohort in Aortic valve disease requiring replacement (n=249). Antibiotic-sterilised homograft aortic valve replacement was evaluated on Survival at 20 years. Antibiotic-sterilised homograft aortic valve replacement yielded a 20-year survival of 55.0% and freedom from structural degeneration of 41.9%, with higher failure risk in younger patients.
