Performance of SynerGraft Decellularized Pulmonary Allografts Compared With Standard Cryopreserved Allografts: Results From Multiinstitutional Data

This study represents a multiinstitutional retrospective comparison of SG and standard cryopreserved allografts used in right ventricular outflow tract reconstruction in a broad range of patient ages. Our results demonstrate that at an intermediate-term to long-term follow-up, conduit dysfunction and pulmonary insufficiency and stenosis are higher among patients receiving standard allografts. We postulate that the improved durability of SG is related to decreased immunogenicity of the SG technology.
