But in recent months, the spotlight has been focused on bioprosthetic aortic valves after concerns were raised about reduced leaflet motion in some valves.The FDA in October 2015 issued a ...

Reduced aortic-valve leaflet motion was shown in patients with bioprosthetic aortic valves. The condition resolved with therapeutic anticoagulation.

Bowdish's team reported that between bioprosthetic valves and mechanical valves, use of the latter dropped from 20% to 10% over the study period, from 2008 to 2019.
