title: Alteration in pulmonary perfusion due to iatrogenic pulmonary vein stenosis: A mimicker of pulmonary embolism.
abstract: 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.
