AORTIC HEART VALVE

A Valve for Life.

sample_product2

Product Highlights

  • The only aortic mechanical valve with FDA, Health Canada, and CE Mark approval for Low INR of 1.5 – 2.0.1*
  • Clinically proven to be safer with less anticoagulation resulting in >60% reduction in bleeding and no increase in thromboembolism.1-2*
  • Unique material and design provide optimal hemodynamics compared with other mechanical and bioprosthetic aortic valves at ≥1 year. 1,3-7

 

*Reduce INR after 3 months of standard therapy.1

On-X Aortic Heart Valve Sizer
On-X Call Out

CYLINDRICAL END

For aortic valve sizes 19-25mm, the cylindrical end is used to find the correct fit.

On-X-Call-Out-Replica-End

REPLICA END

For aortic valve sizes 19-25mm, the replica end is used after sizing to ensure the fit of the valve without obstructing the coronary arteries.

Conical End Sizer

For aortic valve sizes 27/29mm and 31/33mm, the conical end sizer is used to find the correct fit and assure intra-annular positioning.

The only artificial aortic valve to provide flow nearly the same as healthy human aortic valves is the On-X.

Dr. Marc W. Gerdisch, United States

The bleeding risk associated with mechanical valves is almost nullified by a lower anticoagulation option [with the On-X Aortic Heart Valve], and the hemodynamics do not deteriorate over time as do bioprosthetic valves that place the patient in a watchful waiting phase toward the valve end of life.

Dr. Mohanakrishnan Sathyamoorthy, United States

Clinical Evidence

On-X Aortic Heart Valve: 50% Closer to a Normal INR†1

PROACT (Prospective Randomized On-X Anticoagulation Clinical Trial) determined that On-X Aortic Heart Valve patients with an INR of 1.5–2.0 had a >60% reduction in bleeding events and no increase in thromboembolism (TE) compared to patients with an INR of 2.0–3.0.*2 All other mechanical aortic valve anticoagulation should be managed at an INR of 2.0–3.0.3

 

† Normal INR is considered 1.0.1

*Reduce INR after 3 months post-operative standard therapy.4

OPTIMAL HEMODYNAMICS

The On-X Aortic Valve provides optimal mean gradients compared with other bileaflet and bioprosthetic aortic valves at ≥1 year.4-9
