title: Transductal balloon angioplasty for coarctation of the aorta in the neonate: preliminary observations.
abstract: Transductal balloon angioplasty for coarctation of the aorta is described wherein the balloon dilatation catheter is positioned across the coarctation after having passed into the descending aorta from the main pulmonary artery via a patient ductus arteriosus. This procedure was performed in two neonates with excellent immediate clinical results and objective improvement in the pressure gradient. The mechanism of relief of obstruction appears to be ductal dilatation, which allows bypassing the posterolateral shelf of aortic coarctation. This technique is recommended in neonatal coarctations with open ductus arteriosus, especially if the femoral artery cannot be catheterized for performing conventional transfermoral balloon coarctation angioplasty.
