"Micro-Bentall" procedure.

Truncus arteriosus, an anomaly of the conotruncus, is an extremely rare congenital heart disease that affects 1.19% of all patients with congenital heart diseases.  We present a surgical technique using an 8-mm cryopreserved aortic root homograft in the aortic position and a 12-mm pulmonary valved conduit in the right position that allowed us to correct this rare congenital malformation.  The cryopreserved aortic root homograft was considered a priority option for surgical correction.  The neonatal Bentall (micro-Bentall) procedure is a surgically demanding procedure but can be performed successfully by an experienced surgeon.  If we were performing a non-salvage procedure, we would have chosen a decellularized allograft.
