Aortic root and right ventricular outflow tract reconstruction using composite biological valved conduits after failed Ross procedure

Abstract

The Ross procedure or pulmonary autograft has been frequently used for surgical treatment of aortic valve disease. One considerable disadvantage of the Ross procedure is the involvement of two valves (aortic and pulmonary) in treatment of single (aortic) valve disease. Both the aortic and pulmonary valves are at risk for future degeneration. Concurrent failure of both valves after a Ross procedure is rare but presents a significant technical challenge when reoperation is necessary. We describe a novel approach to this complication using composite biological valved conduits comprised of stentless bioprosthetic valves and polyester grafts.
