Primary Outcome Measures:
  • Hemodynamic Performance [ Time Frame: From Implant until Study Enrollment (on average, 7 years) ] [ Designated as safety issue: No ]
    Peak Aortic Gradient (or Peak Velocity), Mean Aortic Gradient, Aortic Insufficiency, Effective Orifice Area

  • Number of Adverse Events as a Measure of Safety [ Time Frame: From Implant until Study Enrollment (on average, 7 years) ] [ Designated as safety issue: Yes ]

    Safety parameters will follow the guidelines for reporting morbidity and mortality after cardiac valvular operations as established by The American Association for Thoracic Surgery and The Society of Thoracic Surgeons.

    Evaluation of the following adverse events:

    • Mortality (all cause and valve-related)
    • Reoperation/reintervention
    • Explant
    • Endocarditis (all and valvular)
    • Thrombosis
    • Thromboembolism
    • Non-structural dysfunction
    • Perivalvular leak (all and major)
    • Bleeding (all and major)
    • Hemolysis
    • Calcification
    • Conduit failure


Estimated Enrollment: 50
Study Start Date: June 2010
Estimated Study Completion Date: June 2014
Estimated Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Retrospective Patients
Pediatric (21 years of age or younger) patients who received a CryoValve SG Aortic Valve distributed during the 2000 to 2003 period as an aortic valve replacement.
Procedure: Echocardiogram
A prospective follow-up Study Echocardiogram will be performed, as applicable, for those subjects who do not have echo data as of January 1, 2009.

Detailed Description:

The CryoValve SG aortic human heart valve is recovered from deceased human donors, treated with the SynerGraft® (SG) process,which is designed to reduce the donor cells present on the graft. The valve is then cryopreserved for storage until use. Removing cells from the heart valve has been shown to reduce a component of the immune response after implant compared to a standard allograft valve. However, it is not known how this affects the long-term durability of the valve.

  Eligibility

Ages Eligible for Study:   6 Years to 27 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Study Population

Pediatric (21 years of age or younger) patients who received a CryoValve SG Aortic Valve distributed during the 2000 to 2003 period as an aortic valve replacement.

Criteria

Inclusion Criteria:

  • Patients implanted with a CryoValve SGAV as an aortic valve replacement.
  • Patients who were ≤ 21 years of age at the time of implant.

Exclusion Criteria:
