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

Important Safety Information

  SJM Regent™ Mechanical Heart Valve


Indication for Use

The SJM Regent™ Mechanical Heart Valve is intended for use as a replacement valve in patients with a diseased, damaged, or malfunctioning aortic valve. This device may also be used to replace a previously implanted aortic prosthetic heart valve.


The SJM Regent™ Mechanical Heart Valve is contraindicated for individuals unable to tolerate anticoagulation therapy.


  • For single use only. Attempts to reuse the valve may result in valve malfunction, inadequate sterilization, or patient harm.
  • Do not use if:
    • The valve has been dropped, damaged, or mishandled in any way.
    • The expiration date has elapsed.
    • The tamper-evident container seal or inner/outer tray seals are damaged, broken or missing.
  • Remove any residual tissue that may impair valve size selection, correct seating of the valve, rotation of the valve, or leaflet motion.
  • Proper valve size selection is crucial. Do not oversize the valve. If the native annulus measurement falls between two SJM Regent™ Mechanical Heart Valve sizes, use the smaller size SJM Regent™ Mechanical Heart Valve.
  • Use only St. Jude Medical ™ mechanical heart valve sizers.
  • The outer tray is not sterile, and should not be placed in the sterile field.
  • To minimize direct handling of the valve during implantation, do not remove the holder/rotator until the valve has been seated in the annulus.
  • Do not use hard or rigid instruments to test leaflet mobility, as this may result in structural damage to the valve or thromboembolic complications. Use a St. Jude Medical™ leaflet tester to gently test valve leaflet mobility.
  • Do not use cutting edge needles in the sewing cuff. If use of these needles is necessary, placement of sutures in the outer half of the sewing cuff is imperative.
  • Never apply force to the valve leaflets. Force may cause structural damage to the valve.
  • Use only the valve holder/rotator packaged with the SJM Regent™ Mechanical Heart Valve to perform valve rotation. Use of other instruments could result in structural damage. The valve holder/ rotator is intended for single use only and should be discarded after surgery.
  • The two retention sutures on the valve holder/ rotator must be cut and removed before the SJM Regent™ Mechanical Heart Valve can be rotated.
  • Do not pass catheters or other instruments through St. Jude Medical™ mechanical heart valves. This could result in scratched or damaged valve components, or leaflet fracture or dislodgment.
  • Cut suture ends short, especially in the vicinity of the pivot guards, to prevent leaflet impingement.


  • Do not touch the prosthetic valve unnecessarily, even with gloved hands. This may cause scratches or surface imperfections that may lead to thrombus formation.
  • Be careful not to cut or tear the valve sewing cuff when removing the identification tag and the holder/rotator from the SJM Regent™ Mechanical Heart Valve.
  • Before placing sutures in the valve cuff, verify that the valve is mounted correctly on the valve holder/rotator.
  • To avoid structural damage, the valve must be rotated in the fully closed position.
  • To minimize rotational torque, verify that the valve holder/rotator is properly seated in the valve, and that the valve holder handle is perpendicular to the valve (Figures 15a and 15b).
  • Remove any loose suture or thread, which may be a source of thrombus or thromboembolism.

Potential Adverse Events

Complications associated with replacement mechanical heart valves include, but are not limited to:

hemolysis; infections; thrombus; or thromboembolism; valve dehiscence; unacceptable hemodynamic performance; hemorrhagic complications secondary to anticoagulation therapy; prosthetic failure; and heart failure or death.

Any of these complications may require reoperation or explantation of the device.
