MITRAL HEART VALVE
A Mitral Valve For Life.
Engineered for Exceptional Clinical Performance.1
Optimal Hemodynamics: mean gradients ≤ 4.4 mmHG across all valve sizes ≥ 25 mm1 reducing risk of PPM.2,3,4
- Optimal Length & Leaflet guards: designed to conceal pledgets, reduce risk of pannus and provide complete annular support when retaining subvalvular structure.2,5,6
1. OPTIMAL VALVE LENGTH
Optimal length designed to conceal pledgets, reduce the risk of pannus, and provide complete annular support while retaining sub-valvular structure. 2,5,6
2. 90° LEAFLET OPENING
90° opening organizes flow, reducing turbulence and thrombogenicity2
Other Mechanical Valves
< 90º leaflet opening can lead to turbulent flow 7
3. PURE ON-X PYROLYTIC CARBON
Designed to reduce thrombogenicity.
Pure Pyrolytic Carbon8,9
Silicone-Alloyed Pyrolytic Carbon8,9
4. CONFORM-X CUFF
- Large, “conforming” Conform-X Cuff designed to provide ease of implant
- Facilitates mitral valve replacement in patients presenting with mitral annular calcification (MAC)10
- Designed to serve as a buffer reducing paravalvular leaks.10
The On-X Conform-X Cuff works very nicely if the annulus is heavily calcified and you need to have the sewing cuff to conform to the annulus. The Conform-X Cuff is quite broad and sits super annular on top covering the annulus.
Mechanical Valves Demonstrate Survival Benefit 1
Study shows survival benefit for recipients of mitral valve mechanical prostheses at 15 years for patients up to 70 years1
