A 21-year-old man, who had undergone Fontan operation for tricuspid atresia type 1b using 21 mm Hancock valved conduit 15 years ago, had right sided heart failure when his heart rhythm turned to atrial fibrillation. On cardiac catheterization, pressure data revealed that trans valved conduit pressure gradient reached to 5.2 mmHg. Chest CT and right atrial angiography showed right atrial wall thrombus. Right upper lobe perfusion defect was detected by lung perfusion scintigraphy. Then he was recommended redo Fontan operation. He underwent resection of stenosed valved conduit, right atrial thrombectomy and reconstruction of new route between right atrium and pulmonary artery with bovine pericardium. He tolerated well that operation and now 3 months passed, he resumed fairly vigorous physical activity.
