Low Anticoagulation Study

Prospective Randomized On-X Valve Anticoagulation Clinical Trial

US FDA IDE Approved

In January of 2006, the FDA approved the first and only IDE (Investigational Device Exemption) lowered anticoagulation trial for a mechanical valve to be conducted at 40 sites in the United States for the On-X Prosthetic Heart Valve.
