New heart treatment helps the body grow a replacement valve | Imperial News | Imperial College...

Surgery to replace faulty heart valves has been possible for more than 60 years, but the treatment has medical drawbacks, both with mechanical or biological valves. But what if the body’s natural repair mechanisms could be harnessed to build a living heart valve, right where it is needed? Recent studies led by researchers at Harefield Hospital and Imperial’s National Heart and Lung Institute suggest that this approach is entirely possible.
