A 67-year-old man presented with general malaise with New York Heart Association (NYHA) functional class III symptoms. A chest x-ray and 3-dimensional computed tomography showed a dense circular band of calcification entirely encircling the atrioventricular groove (A and B). The main pulmonary artery was compressed by the calcified band just above the pulmonary valve, and post-stenotic dilation of the pulmonary artery was seen (C, arrow). Transthoracic echocardiography revealed severe pulmonary artery stenosis (PS) (peak pressure gradient: 68 mm Hg). Cardiac catheterization revealed equal end-diastolic pressures in both ventricles and dip and plateau phenomenon. The patient received a diagnosis of severe PS due to an extensive pericardial calcified ring and underwent resection of the ring using cardiopulmonary bypass (D). The patient had an uneventful post-operative course with full functional recovery to NYHA functional class I. There were no pathological findings suggesting tuberculosis. AV = aortic valve; LA = left aorta; PA = pulmonary artery; RV = right ventricle.
