Body donation as a grateful gift for a long and active life with a Björk-Shiley valve

Area of Science:

• Cardiovascular Surgery
• Biomedical Engineering
• Geriatric Medicine

Background:

• The Björk-Shiley convexo-concave (BSCC) prosthetic aortic valve was implanted in a patient 34 years prior.
• Earlier BSCC valve designs are associated with a high mortality rate due to potential failure.
• Prosthetic valve longevity is a critical factor in patient outcomes and quality of life.

Observation:

• An 87-year-old male donated his body for anatomical study.
• The patient had a history of a BSCC prosthetic aortic valve implanted 34 years ago.
• He remained highly active, working as a firefighter, throughout his life.

Findings:

• Dissection revealed an enlarged heart but no significant thrombosis or fibrosis around the valve.
• No pathological signs indicative of valve failure were identified.
• The BSCC prosthetic aortic valve demonstrated exceptional longevity and biocompatibility in this case.

Implications:

• This case suggests that some BSCC valves may achieve exceptionally long functional lifespans.
• Understanding the factors contributing to such longevity could inform future prosthetic valve design.
• Long-term survival with older prosthetic valves is possible, challenging established mortality rates.
