A late-breaking study presented today at the 2025 Society of Thoracic Surgeons (STS) Annual Meeting reveals that mechanical aortic valve replacements (AVRs) provide significant long-term survival benefits for patients aged 60 and younger compared to bioprosthetic valves. The study, leveraging data from the STS Adult Cardiac Surgery Database (ACSD), offers the most comprehensive analysis to date of prosthetic valve outcomes, encompassing over 100,000 patients.
The study addressed a critical question in cardiac surgery: how age and valve type influence outcomes for patients undergoing surgical AVR. It found that patients aged 60 and younger had lower all-cause mortality with mechanical valves.
Key findings include:
- Decline in mechanical valve use: Despite superior outcomes in younger populations,…
