Correction of truncus arteriosus after pulmonary artery banding.
Correction of truncus arteriosus can be performed in the older child with low mortality. However, many infants are severely symptomatic with increased pulmonary blood flow and require banding of the pulmonary artery at an age when correction has a high mortality. The pulmonary artery band can complicate the usual technique of the subsequent repair. An alternative approach following pulmonary artery banding is to interrupt the pulmonary artery--truncus continuity with a patch from within the truncus and then place the external valved conduit onto the pulmonary artery in an end-to-side manner.
