  		Fig. 1B. —Left superior pulmonary vein occlusion and venous infarction after radiofrequency ablation in 31-year-old man with refractory atrial fibrillation. Contrast-enhanced CT scans (2.5-mm collimation, lung window) show scattered ground-glass opacities and focal peripheral consolidation in left upper lobe consistent with venous infarction. Note thickened interlobular septa (arrows) visible on C.

  		Fig. 1D. —Left superior pulmonary vein occlusion and venous infarction after radiofrequency ablation in 31-year-old man with refractory atrial fibrillation. Contrast-enhanced CT scan (2.5-mm collimation, mediastinal windows) shows occlusion of left superior pulmonary vein with soft-tissue attenuation (open arrow) surrounding expected location of vein and left-sided pleural thickening. Note contrast material (curved arrow) in right superior pulmonary vein.
