Aortic Mechanical Heart Valve

Regent™ Aortic

Implant Confidently

The Regent™ aortic mechanical valve offers surgeon-friendly implantability, featuring a low valve implant height that helps ensure coronary ostia clearance. Two distinct cuff types—FlexCuff™ or Standard Cuff—provide you with different options. The Regent™ valve features exceptional hemodynamics in small aortic root patients.1*

Because prosthesis-patient mismatch (PPM) can be problematic in the aortic position, Abbott designed the Regent™ valve specifically to avoid this issue. The orifice-to-annulus ratio of the Regent™ valve ensures large effective orifice areas (EOAs) and reduces PPM.2

The Regent™ valve shows low thromboembolism, thrombosis, and bleeding over a wide international normalized ratio (INR) range, making this valve an excellent choice.3-6

*Measured one year post-surgery.
