Mechanical Heart Valves (MHV) - Regent™ Features

SURGICAL HEART VALVES
MECHANICAL HEART VALVES (MHV)

Unique design features have established Abbott mechanical heart valves—including the Regent™ and Masters Series—as a gold standard for reliability and performance, while maintaining low complication rates over the long term.

REGENT™

REGENT™ GIVES YOU IMPLANTABILITY OPTIONS

Low valve implant height helps ensure coronary ostia clearance

Replica sizing with the 907 sizer gives you confidence that you are using the most appropriately sized valve

Low valve implant height helps ensure coronary ostia clearance

Replica sizing with the 907 sizer gives you confidence that you are using the most appropriately sized valve

TWO DISTINCT CUFF TYPES PROVIDE YOU WITH DIFFERENT OPTIONS

FLEXCUFF™

STANDARD CUFF

The Regent™ aortic valve features exceptional hemodynamics in small aortic root patients^15,16*

Laminar downstream flow through a Regent™ valve provides patients optimal hemodynamic performance and low gradients that mitigate shear stress and and thrombogenicity⁷

*Measured one-year post-surgery.
