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.

The tiny valve is made in Minnesota and was originally developed by St. Jude Medical, a medical device manufacturer that was purchased by Abbott in January 2017 for $25 billion.
