A study presented 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 with a size 21 mm mechanical valve had better survival compared to both size 19 and 21 mm biological valves. The study confirmed that severe PPM is a significant risk factor for poor long ...

Between mechanical valve (n=411) and biological valve (n=202) cohorts, those with mechanical valves were disproportionately more likely to come from low- or middle-income countries (81% vs 38%).

A study led by the University of Bristol, Bristol, England, has found that mechanical heart valves provide better long-term survival than biological heart valves in patients aged 50-70 years.

Overall, mechanical valve use decreased by about half over the study period, from almost 20% in 2008 to below 10% in 2019. Compared with patients undergoing mechanical AVR, those receiving ...

Patients aged between 50 to 70 years with a mechanical heart valve replacement had better long-term survival compared to those with a biological valve, new research led by the University of ...
