Abstract:
We describe here successful palliative repair of tricuspid atresia, hypoplastic right ventricle, transposition of the great arteries, and hypoplastic aortic arch in a neonate. The repair consisted of the Norwood procedure with a rudimentary right ventricle to pulmonary artery shunt, which was located on the right side of a neo-aorta. This procedure could be a useful adjunct to avoid left ventriculotomy and its subsequent dysfunction.
