Reconstructing of the right ventricular outflow tract using an inlayed aortic root homograft.

Abstract

Our experience with the use of a fresh antibiotic sterilized aortic root homograft inlayed into the right ventricular outflow tract is described. With this technique, compression of the graft between the sternum and heart has been avoided and residual right ventricle to distal pulmonary artery pressure gradients have been small. The functional status of the survivors is good over a follow-up period of up to 3 yr. The advantages of this approach compared with a conventionally placed heterograft conduit or an outflow tract gusset are discussed.
