Balloon atrial septostomy in complete transposition of great arteries in infancy.

Abstract

The results of 26 completed balloon atrial septostomies in complete arterial transposition in infancy are described, and complications discussed. Of 7 deaths following this procedure, 3 were clearly or probably related to it or to its failure to produce an adequate septal defect, while 4 were unrelated. Atrial perforations occurred on 4 occasions.
