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.
