SURGICAL REPLACEMENT AORTIC & MITRAL VALVE

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 ingrowth
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 Mechanical Heart Valves: A Gold Standard
