title: [Supravalvular pulmonary stenosis following anatomic correction of transposition of great vessels: report of a successful balloon dilatation].
abstract: Primary anatomical repair of TGA has several theoretical advantages over conventional atrial baffle techniques. However, one of the most common postoperative complications of the new technique is the development of an obstruction at the arterial anastomosis to the pulmonary artery (PA). A supravalvular pulmonary stenosis developed progressively over the first months after an arterial switch operation of a simple TGA in a newborn infant. The diagnosis was easily performed by Doppler-echocardiographic follow-up studies. Hemodynamic assessment by cardiac catheterization performed when the patient was five months old revealed a systolic gradient of 76 mm Hg at the arterial anastomosis. Percutaneous balloon angioplasty was successfully performed.
