Transection at the cavoatrial junction and left superior
cavopulmonary anastomosis
This procedure was described in a 2 year old child with tricuspid
atresia. Under circulatory arrest at 18°C, the anomalous vein was
transected at its junction with superior caval vein. The distal end was
oversewn. The proximal end was mobilized and was anastomosed to left
pulmonary artery. The azygous vein was ligated. The pulmonary trunk was
divided at the level of previous banding. A hemi-Fontan type of right
cavopulmonary anastomosis was then performed, along with a
Damus-Kaye-Stansel procedure. A year later, the child underwent a
fenestrated lateral tunnel Fontan procedure.56
