Case Report (n=1)
Ventilation-perfusion scintigraphy can effectively demonstrate the physiological effects of pulmonary vein stenosis following atrial fibrillation ablation, correlating well with MR pulmonary angiography.
Perfusion scintigraphy and MR angiography may concordantly quantify flow restriction in post-ablation pulmonary vein stenosis; leaves open optimal modality selection.
A case of pulmonary vein stenosis as a result of prior atrial fibrillation focus procedures for atrial fibrillation, correlated with magnetic resonance (MR) pulmonary angiography, is presented. Restricted flow to the right lung in similar quantities measured by nuclear medicine and MR techniques is observed, with perfusion scintigraphy demonstrating decreased but not absent flow to the right lung and left lower lobe and with MRI demonstrating restriction of flow through the right and left lower pulmonary veins. The sharp differences in venous outflow can be seen by MR, whereas their effects are visible by scintigraphy.
