[Double-balloon angioplasty of pulmonary venous drainage obstruction after the Senning procedure in transposition of the great vessels].
A six and half-year old boy with Senning operation for transposition of the great arteries, showed recurrent atrial flutter and obstruction of the pulmonary venous atrium from the early postoperative period. By Doppler examination a peak gradient of 13 mmHg at the isthmus level was recorded in the pulmonary venous atrium. A successful double-balloon dilatation of stenotic area was performed via a retrograde, transaortic, approach through angioplasty. Six months after the procedure the enlargement of the stenosis persists, and the patient is clinically asymptomatic and arrhythmia-free without medication.
