CONFIDENTLY IMPLANT THE MOST TRUSTED AORTIC AND MITRAL MECHANICAL VALVES IN THE WORLD

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 have established Abbott mechanical heart valves as the gold standard for reliability and performance.

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

Important safety information
  • SJM REGENTTM MECHANICAL HEART VALVE
    INDICATION FOR USE


    The SJM RegentTM 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.

    CONTRAINDICATIONS

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

    WARNINGS

    • 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 RegentTM Mechanical Heart Valve sizes, use the smaller size SJM RegentTM Mechanical Heart Valve.
    • Use only St. Jude MedicalTM 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 MedicalTM 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 RegentTM 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 RegentTM Mechanical Heart Valve can be rotated.
    • Do not pass catheters or other instruments through St. Jude MedicalTM 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.

    PRECAUTIONS

    • 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 RegentTM 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.

    • Cut suture ends short, especially in the vicinity of the pivot guards, to prevent leaflet impingement.
    • Three cases of impeded leaflet motion not satisfactorily explained were reported in a survey of 149 centers reporting on 4,934 patients implanted over a period of three (3) years. A number of other cases occurred early in the investigation of this prosthesis; however, the rates of occurrence are not statistically determinable.
