Design-driven hemodynamic confidence & low thrombogenicity
Abbott mechanical heart valves lead the way with a proven bileaflet design that results in low thrombogenicity and excellent patient outcomes.
- Leaflets open to an 85-degree angle in systole due to their upstream positioning, enabled by unique pivot guards (shown at right)
- Strong, uniform velocities within hinge recesses aid washout of blood elements3
- Low carbon surface area means less thrombus formation
- Orifice-to-annulus ratio (as high as 84%) ensures large effective orifice areas (EOAs) and reduces prosthesis-patient mismatch4
Unique Design Features
THE PIVOT GUARD DESIGN | AN ABBOTT HALLMARK
Featured in all Abbott Mechanical Heart Valves, the Pivot Guard offers benefits both during implant and post-implant
- Recessed design minimizes interaction with sub-annular native mitral valve apparatus
- Minimized carbon surface area can lessen thrombus formation
- Pivot guards help shield pivot mechanism from pannus in growth
- Enables a consistent 85-degree opening angle, promoting minimized leaflet flutter and more laminar flow through the orifice5
LOW THROMBOGENICITY | A NECESSITY IN MHV REPLACEMENTS
Designed with Low Thrombogenicity at the Forefront
- Large internal diameters up to 26.1 mm available promote low pressure gradients6
- Low gradients can help minimize shear stress and thrombogenicity7
- Uniform velocities within hinge recesses help aid washout of blood elements3
- Abbott hinge design enables complete leaflet sweep, further aiding washout
- Abbott hinge design enables complete leaflet sweep, further aiding washout
