title: Operative balloon pulmonary valvuloplasty.
abstract: Closed operative pulmonary valvulotomy for relief of critical pulmonary valve stenosis can be performed effectively by intraoperative use of a balloon catheter without inflow occlusion or hemodynamic instability and with minimal blood loss. Follow-up evaluation indicates adequate growth of the valve.
