[Clinical experience of adjustable pulmonary artery banding]

Pulmonary artery banding has been a useful palliative procedure for infants with congenital cardiac anomalies associated with excessive pulmonary blood flow. We have experienced some cases that the band was not sufficient enough to reduce the pulmonary artery pressure in complex cardiac anomalies. Therefore, we developed a new adjustable pulmonary artery banding system which can be re-adjusted extrathoracically without reoperation. We used this system in seven infants with congenital cardiac lesions and obtained good results.
