ObjectiveTo evaluate the outcome of the cardiac catheter angiograplasty for patients after Norwood procedure.Methods13 patients，who had undergone Norwood procedure(prior to Glenn procedure)received cardiac catheterization and angiography.Interventional therapy was performed in 12 patients as indicated.ResultsAngioplasty was carried out for re-coarctation in 6 of the 13 patients.1 patient with left pulmonary artery stenosis received balloon dilation and 3 months later a stent implantation.A stent was implanted to improve the pulmonary blood flow in 2 patients with Sano-Shunt stenosis and 1 patient with BT-Shunt stenosis.Transcatheter coil embolization was performed in 3 of the 4 patients with systemic to pulmonary collateral vessels.The other one was scheduled for Glenn procedure the next day.ConclusionThe incidence of hemodynamic restrictions after Norwood procedure is high(12 of 13 patients).Postoperative angiography and hemodynamic assessment for diagnisis and interventional treament for new pulmonary artery or aortery arch stenosis is necessary after Norwood procedure.35 refs，1 fig，1 tab.
