Successful reoperation of the valveless calcified right atrium to right ventricle conduit in an adult patient with tricuspid atresia after Fontan procedure.

A 31-year old woman with tricuspid atresia, after Bjork Fontan modification and reoperation due to homograft narrowing, was evaluated because of progressive exercise intolerance; she was planning a pregnancy. The right atrium (RA) to right ventricle (RV) homograft narrowing and calcification with significant reversal flow were found. Successful reoperation was performed-calcified conduit was excised and extracardiac pulmonary homograft tipped with vascular prosthesis was implanted between the RA and the RV.
