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 ...

A UK study has suggested that the choice of mechanical or biological heart valves for patients aged 50-70 years may need to be reconsidered.

Tissue valve: These valves are made up of bovine pericardium and can last up to 12 to 15 years. There are fewer chances of the body rejecting a tissue valve as it is made of the natural compound.

11-year-old receives living donor heart valve to replace artificial one in breakthrough surgery Doctors at Children's National Hospital performed Preston's surgery.

Mechanical valves, made of metal and plastic, last indefinitely. However, they can cause blood clots, so a person with a mechanical valve has to take blood thinners, which carry their own risks.

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 ...

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%).

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.

LOS ANGELES -- Survival outcomes favored mechanical valves for isolated surgical aortic valve replacement (SAVR) for people until age 60, after which a tissue valve may start to have an advantage ...

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 ...

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 ...

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.
