This is a prospective, non-randomized, multi-center study designed to evaluate safety and effectiveness of the ATS 3f Enable Aortic Bioprosthesis in a patient population undergoing isolated aortic valve replacement with or without concomitant procedures. The Enable Aortic Valve is an equine pericardial stented bioprosthesis.

Primary Outcome Measures:
  • Migration [ Time Frame: One Year ] [ Designated as safety issue: Yes ]
    Migration is defined as complete or partial displacement (tilting) of the device from its original locus resulting in coronary ostia blockage, perivalvular leak, or incompetence.

  • Thromboembolism/Thrombosis [ Time Frame: One Year ] [ Designated as safety issue: Yes ]
    Valve related thromboembolism and valvular thrombosis.

  • Hemorrhage (all and major) [ Time Frame: One Year ] [ Designated as safety issue: Yes ]
    All bleeding events regardless of whether or not the event is related to anticoagulation therapy and will be categorized as minor and major events.

  • Perivalvular Leaks (all and major) [ Time Frame: One Year ] [ Designated as safety issue: Yes ]
    All perivalvular leak events will be reported.

  • Endocarditis [ Time Frame: One Year ] [ Designated as safety issue: Yes ]
    Study valve endocarditis.

  • Hemolysis [ Time Frame: One Year ] [ Designated as safety issue: Yes ]
    Hematology/Chemistry data will be analyzed to determine if significant subclinical or unreported hemolysis is occuring.

  • Structural Valve Deterioration [ Time Frame: One Year ] [ Designated as safety issue: Yes ]
    Structural valve deterioration data will be collected.

  • Non-Structural Dysfunction [ Time Frame: One Year ] [ Designated as safety issue: Yes ]
    Perivalvular Leak, Hemolysis, Entrapment by pannus, tissue or suture, Inappropriate sizing or positioning, and Distortion.

  • Re-operation, Explant, Death (all Deaths and valve related) [ Time Frame: One Year ] [ Designated as safety issue: Yes ]
    Re-operations, Explant, and Death (all Deaths and valve related)

Secondary Outcome Measures:
  • Effectiveness Endpoint - NYHA Classification, Hemodynamic Performance [ Time Frame: One Year ] [ Designated as safety issue: No ]
    NYHA classification to asses improvement of the cardiac status, Hemodynamic Performance analysis based on Doppler echocardiographic studies.

Replacement Aortic Heart Valve

Detailed Description:
The ATS 3f Enable Aortic Bioprosthesis is intended for those patients whose prognosis without surgical replacement of the diseased natural valve is unacceptably poor in terms of survival and/or quality of life in the opinion of the attending physicians. For these patients, there are a number of widely accepted prosthetic heart valves in use.

Ages Eligible for Study:   21 Years and older   (Adult, Senior)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • The patient requires isolated aortic valve replacement with or without concomitant procedures such as coronary artery bypass or another valve repair. (The three remaining valves must be of native tissue).
  • The patient is geographically stable and willing to return to the implant site for follow-up visits.
  • The patient has been adequately informed of risks and requirements and consent to his/her participation in the clinical study.
  • If this patient is female and of childbearing potential, patient has a negative pregnancy test within seven (7) days prior to the study procedure.

Exclusion Criteria:

  • The patient requires replacement of two or more valves.
  • The patient is < 20 years of age.
  • The patient has a non-cardiac major or progressive disease, which in the Investigator's experience produces an unacceptable increased risk to the patient, or results in a life expectancy of less than 24 months.
  • The patient is an intravenous drug and/or alcohol abuser.
  • The patient presents with active endocarditis or other systemic infection.
  • The patient has had previous valve replacement surgery, including previous implant and then explant of the ATS 3f Enable Aortic Bioprosthesis (Model 6000) or placement of a rigid annuloplasty ring in the mitral position.
  • The patient is participating in concomitant research studies of investigational products.
  • The patient presents with dilatation of the ascending aorta, Marfan Syndrome, Ehlers-Danlos syndrome, cystic medial degeneration, or other condition causing the ascending aorta to be irregular in geometry or physiology as seen via preoperative imaging.
  • The patient has chronic renal failure.
