Aortic Valve Replacement Solutions Heading

No Other Mechanical Valve Has:

  • 90° leaflets:4 promotes laminar flow
  • Pure pyrolytic carbon: reduces thrombogenicity5
  • Flared inlet: organizes flow; prevents pannus

On-X Aortic Valve: INR 1.5-2.0*

  • >60% reduction in bleeding6
  • No increase in thromboembolism (TE)6
  • 2017 AHA/ACC Guidelines: On-X Aortic Valve INR 1.5-2.0 in patients without risk of TE7,*

    *Reduce INR after 3 months standard therapy.4,6

Advantages of the Ross Procedure Include:

  • No need for lifelong anticoagulation medicine (blood thinner)1
  • Excellent hemodynamic performance (blood flow) at rest and during exercise2,3
  • Only operation shown to restore life expectancy similar to that of the general population1
  • Quality of life similar to those who have not undergone aortic valve replacement1
  • Low risk of thromboembolism (blood clots)1
