Key result
Angioplasty restores pulmonary perfusion in iatrogenic pulmonary vein stenosis mimicking massive PE.
Why the study?
Iatrogenic pulmonary vein stenosis after atrial radiofrequency ablation can alter pulmonary perfusion and mimic massive pulmonary embolism on V/Q scintigraphy, complicating diagnosis.

Iatrogenic pulmonary vein stenosis post-ablation can mimic massive pulmonary embolism on V/Q scintigraphy, highlighting the need for careful differential diagnosis.
Iatrogenic pulmonary vein stenosis (PVS) is a known, yet rare, complication of atrial radiofrequency ablation. Alterations in pulmonary perfusion may mimic massive pulmonary embolism on a ventilation/perfusion (V/Q) scintigraphy. This is particularly important due to the overlap in presenting clinical symptoms. The present case illustrates the functional significance of PVS and the changes in perfusion in response to angioplasty.

Ostwani et al. (2011) conducted a case report in Iatrogenic pulmonary vein stenosis (n=1). Angioplasty was evaluated on Changes in pulmonary perfusion. Angioplasty altered pulmonary perfusion in a patient with iatrogenic pulmonary vein stenosis that mimicked massive pulmonary embolism on V/Q scintigraphy.
