Abstract: | A case of severe pulmonary valvar stenosis and infundibular obstruction has been reported. Infundibular obstruction was so severe that no catheter could be advanced into the pulmonary artery. Propranolol, 0.5 mg given intravenously, reduced the obstruction and allowed the balloon dilatation of the pulmonary valve to be carried out without complication. Subsequently oral propranolol helped to remove the infundibular obstruction. We strongly recommend the use of propranolol when infundibular obstruction is present prior or after the balloon pulmonary valvuloplasty. |
