Angiocardiography of multiple ventricular septal defects in infancy.

Biplane cineventriculography in 364 infants 1 year of age or younger demonstrated multiple ventricular septal defects (VSDs) in 56 (15%).Among 111 infants with VSDs (with or without patent ductus arteriosus), 18 (16%) had multiple VSDs, whereas 14 of 39 infants (36%) with VSD and coarctation of the aorta had multiple VSDs.The incidence of multiple VSDs in infants with tetralogy of Fallot was 7% (eight of 117), in infants with d-transposition of the great arteries 19% (eight of 43), and in infants with common atrioventricular canal 15% (eight of 54).Perioperative axially angled cineangiocardiography correctly predicted the presence of multiple VSDs in 13 of 15 infants (86%) who underwent operation.
