title: Surgical treatment of pulmonary venous tunnel stenosis [corrected] after modified Senning procedure.
abstract: A 13-year-old male was admitted to undergoing correction of a pulmonary venous baffle stenosis (PVBS) after a modified Senning procedure was performed by the age of five months. Recurrent Pulmonary congestion and pneumonia episodes were followed by echocardiography and cardiac catheterization that confirmed PVBS. Previous catheter balloon angioplasty was attempted, and a surgical revision was done under cardiopulmonary bypass. The bovine pericardial patch used for augmentation of the right atrium, retracted and calcified producing PVBS. Stenotic area was excised and enlargement was done with polytetrafluoroethylene membrane. Intraoperative transesophageal echocardiogram showed relief of stenosis.
