On-X Prosthetic Heart Valves

On-X Prosthetic Heart Valves

Safer With Less Warfarin

  • The only aortic mechanical heart valve FDA approved with less warfarin
  • >60% reduction in bleeding
  • No increase in thromboembolism (TE)

On-X Life Technologies is a leading manufacturer of artificial heart valve replacement and repair products. On-X aortic and mitral prosthetic valves are FDA approved and have been safely implanted in more than 260,000 patients worldwide.

The On-X Aortic Valve is a newer generation heart valve made of a unique material and design characteristics compared with earlier generations of mechanical heart valves. The On-X Aortic Valve is the only mechanical valve with FDA and CE approval as being clinically proven safe with significantly less blood thinner (warfarin).18,† The American Heart Association guidelines state that less blood thinner may be reasonable for patients with the mechanical On-X Aortic Valve.3 In a prospective randomized clinical trial, On-X Aortic Valve patients with a reduced blood thinner dose had > 60% fewer bleeding events without an increase in risk of stroke.18 The On-X Aortic Valve, as a mechanical heart valve, has a much lower risk of reoperation than tissue valves, with the additional benefit of less bleeding risk than other mechanical aortic valves because of the significantly lower amount of blood thinner required.3,†

If you are under the age of 70 years and need aortic valve replacement, ask your doctor about the On-X Aortic Valve, the only mechanical valve that is both likely to last a lifetime3,17 and safer with less blood thinner.18 ,†
