Anastomosis of the left juxtaposed atrial appendages in a patient with tricuspid atresia

A 9-month-old boy with left juxtaposition of the atrial appendages, tricuspid atresia, pulmonary atresia, and ventriculoarterial discordance underwent anastomosis between the atrial appendages after failure of balloon/blade atrial septostomy because of restrictive atrial septal defect. For surgical creation of atrial communication in patients with juxtaposed atrial appendages, anastomosis between the atrial appendages seemed to be safer, more effective, and less invasive than septectomy by Blalock-Hanlon technique or inflow occlusion technique.
