Mechanical valve: These valves are made up of pyrolytic carbon and are durable in nature. ... There are fewer chances of the body rejecting a tissue valve as it is made of the natural compound.

Replacement heart valves that grow inside the body are a step closer to reality following studies led by researchers at Imperial. The results are published in Communications Biology.

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.

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 has found.

A prosthetic valve in the mitral position was a predictor for valve thrombosis (OR 3.3, 95% CI 1.9-8.0); body mass index was predictive of any thromboembolic event (HR 1.1, 95% CI 1.0-1.1).
