SGAV: CryoValve® SG Aortic Human Heart Valve Combination Study
Study Details
Study Description
Brief Summary
The purpose of this study is to assess the probable benefit of CryoValve SG Aortic Human Heart Valve used in pediatric patients as an aortic valve replacement.

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.

---|---|
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.

Outcome Measures
Primary Outcome Measures
- Hemodynamic Performance [From Implant until Study Enrollment (on average, 7 years)]
Peak Aortic Gradient (or Peak Velocity), Mean Aortic Gradient, Aortic Insufficiency, Effective Orifice Area
- Number of Adverse Events as a Measure of Safety [From Implant until Study Enrollment (on average, 7 years)]
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
