TRANSCATHETER MANAGEMENT OF PULMONARY VENOUS PATHWAY OBSTRUCTION WITHATRIAL BAFFLE LEAK FOLLOWING MUSTARD AND SENNING REPAIR

Two patients presenting with pulmonary venous baffle obstruction follo wing Mustard or Senning repair of transposition of the great arteries were successfully treated with percutaneous balloon dilatation. At the time of baffle dilatation, a significant systemic to pulmonary venous Mustard baffle leak was successfully closed with a Rashkind ductal oc cluder device. Specific features pertaining to the morphology of the b affle defect that allowed successful catheter occlusion are discussed and compared to that found in a Senning patient. The important adjunct ive role of transoesophageal echocardiography within the catheterizati on laboratory is emphasized. (C) 1993 Wiley-Liss, Inc.
