A new proposal for the treatment of right ventricular dysfunction in late postoperative period of patients submitted to Senning operation is presented. The technique could be used in cases originally with transposition of the great arteries associated with pulmonary stenosis and a large VSD. A 12-year-old patient, who had been submitted, 8 years before, to an atrial inversion associated with closure of a large VSD and relieve of a pulmonary stonosis was submitted to this new operation. Senning operation was undone thus reestablishing atrio-ventricular concordance; the patch used for closure of VSD was removed, and the aorta was connected to the left-ventricle. Pulmonary artery was cut transversally, adjacent to the valvar horizontal plane. The proximal extremity was sutured and the distal was connected to the right ventricle through a valvar tube graft of bovine pericardium. The clinical course was uneventful and the patient improved from functional class IV to I/II.
