A minimally invasive procedure gives one patient a second chance — and signals major strides in cardiovascular care.

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 led by the University of ...

A total of 1,708 (61% male) patients with an average age of 63 years were included with 1,191 (69.7%) receiving a biological valve replacement.

This pioneering innovation envisions the development of biological heart valves that can grow and be accommodated naturally within the human body. This opens the door to a new era in heart disease ...

About 13,000 heart valve replacement operations are performed in England each year and 300,000 worldwide, a number set to rise as heart disease rates climb. By 2050, 850,000 replacements a year ...

Biological valves come from animal tissue. They last 10-20 years. That’s not as long as mechanical valves, but they don’t lead to clots and you won’t need blood thinners.

A valve made of human collagen derived from cell cultures opens up new possibilities for treating pediatric heart diseases, according to a study published in Science Translational Medicine. Two ...

Biological heart valves. The advantage of biological heart valves is that most people do not need to take lifelong blood thinners unless they have other conditions (such as atrial fibrillation ...
