Key result
Interventional stenting resulted in no improvement in the perfusion abnormality in a single patient with iatrogenic pulmonary vein stenosis following radiofrequency ablation.
Case Report (n=1)
Iatrogenic pulmonary vein stenosis after AF ablation can cause ventilation-perfusion mismatch mimicking pulmonary embolism that may not improve with stenting.
Stenting may not resolve perfusion mismatch in iatrogenic pulmonary vein stenosis; leaves open optimal management strategies for this post-ablation complication.
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.

Wong et al. (2009) conducted a case report in Right superior pulmonary vein stenosis (n=1). Interventional stenting was evaluated on Improvement in perfusion abnormality. Interventional stenting resulted in no improvement in the perfusion abnormality in a single patient with iatrogenic pulmonary vein stenosis following radiofrequency ablation.
