Abstract
A lobar ventilation-perfusion mismatch is reported in a patient with right superior pulmonary vein stenosis, developing after radiofrequency ablation for atrial fibrillation. Radionuclide lung perfusion tomography was performed to assist with clinical management. Serial planar lung scintigraphy demonstrated no improvement in the perfusion abnormality despite interventional stenting. Iatrogenic pulmonary vein stenosis may potentially mimic pulmonary embolic disease.
