Successful repair of recurrent coarctation after neonatal heart transplantation.

Neonatal orthotopic heart transplantation is an attractive primary surgical therapy for severe uncorrectable congenital heart defects such as variants of the hypoplastic left heart syndrome. Aortic arch reconstruction is frequently required to repair the hypoplastic aortic arch and the coarctation at the time of graft implantation. Residual coarctation of the aorta after neonatal heart transplantation for such a condition has satisfactorily been treated with percutaneous balloon dilatation. We describe the successful surgical repair of a recurrent coarctation of the aorta via a sternotomy in a 2-year-old patient who had previously undergone neonatal orthotopic heart transplantation. Postoperative periodic investigations have not shown any evidence of obstruction across the site of the primary end-to-end anastomosis.
