An infant with tricuspid atresia and normally related great arteries presented with increased pulmonary blood flow and congestive heart-failure. Despite intensive medical management the patient developed persistent collapse of the left lung attributed to compression of the left main-stem bronchus between the distended left pulmonary artery and enlarged left atrium. Marked clinical improvement resulted from banding the main pulmonary artery.
