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.

PROACT Study Drug Therapy Groups
| Low risk aortic patients: | clopidogrel plus aspirin (81mg/day) |
|---|---|
| High risk aortic patients: | INR of 1.5-2.0 plus aspirin (81mg/day) |
| Mitral patients: | INR of 2.0-2.5 plus aspirin (81mg/day) |
| Control groups: | American Heart Association/American College of Cardiology standards for mechanical heart valves |

Reduction of turbulence provided by a more natural design has lowered complication rates for the On-X Prosthetic Heart Valve.
CAUTION: Federal law restricts this device to sale by or on the order of a physician. Refer to the instructions for use that accompany each valve for indications, contraindications, warnings, precautions and possible complications. CAUTION: This investigational use of this device is limited by Federal law to investigational sites.
