Allograft Valve Banking: Techniques and Technologyases, the availability of this human tissue will become a factor. With approximately 25,000 adult aortic valve replacements and 5000 pediatric reconstructions done annually in the United States,. ways to maximize the number of heart valves available for transplant must be sought.

Left Ventricular Outflow Tract Reconstructionsnical surgical result. The surgeon must view the use of allograft tissue as a tool for the reconstruction of the left ventricular outflow tract rather than as an implant of a device. This requires mastering both the analysis of the outflow tract as well as multiple methods for its reconstruction.

Historical Development of the Use of Homograft Valvesstrate excellent valve function for up to 20 years. Kerwin’s subsequent reports support the contention that aortic leaflet homograft pliability and performance were well preserved in these early patients.. These clinical trials were preceded by laboratory investigations, especially that of Lam and coworkers..

From the early days of using wet-stored “nonviable” homografts to current methods of transplanting cryogenically preserved “viable” allografts, the superiority of human heart valve implants has been well documented.. However, as the clinical utilization of heart valve allografts incre
