Key result
Analysis of 8 pyrolytic carbon-containing heart valve prostheses implanted for a mean of 50 months showed undetectable wear, suggesting abrasive wear will not be a late complication.
Why the study?
Do pyrolytic carbon-containing heart valve prostheses exhibit less abrasive wear compared to Teflon valves?
Observational (n=8)
Do pyrolytic carbon-containing heart valve prostheses exhibit less abrasive wear compared to Teflon valves?
Pyrolytic carbon-containing heart valve prostheses show undetectable abrasive wear after up to 85 months of implantation, suggesting durability against late wear complications.

Supports durability of pyrolytic carbon valves in retrieved samples; leaves open confirmation in larger prospective cohorts.
Schoen et al. (1982) conducted an observational in Heart valve replacement (n=8). Pyrolytic carbon-containing heart valve prostheses vs. Teflon Beall Model 104 valve was evaluated on Abrasive wear. Analysis of 8 pyrolytic carbon-containing heart valve prostheses implanted for a mean of 50 months showed undetectable wear, suggesting abrasive wear will not be a late complication.
