A successful repair of tricuspid atresia by modified Björk's procedure--a case report.

A ten-year-old Japanese boy with tricuspid atresia type IB was treated by direct anastomosis from the right atrium (RA) to the right ventricle (RV), entirely with autogenous material. An incision of the RA anterior wall was designed for a flap of RA appendage. A valveless conduit was created, with this flap and a large piece of pericardium. Atrial septal defect (ASD) and ventricular septal defect (VSD) were closed with a patch. Cardiac catheterization and angiocardiography two months postoperatively, showed good results of the surgery.
