Abstract
Abstract In seven children with obstructed right ventricle‐to‐pulmonary artery conduits, balloon dilatation (BD) was performed 10–58 months after insertion of the conduit. Average valve gradient was reduced from 69 to 32 mmHg. Obstruction at the conduit‐branch pulmonary artery connection became apparent after dilatation of the valve; these distal stenoses also were dilated. It is concluded that the useful lifetime of a right ventricle (RV) to pulmonary artery (PA) conduit may be extended by BD of an obstructed biological valve and/or BD of a stenotic conduit‐pulmonary artery anastomosis.
