Figure 2From: Pulmonary vein isolation in patients with paroxysmal atrial fibrillation is associated with regional cardiac sympathetic denervation Example of a patient with a new innervation defect after PVI. Short axis slices of the left ventricle 15 min and 4 h after 123I-mIBG injection before and after PVI. Regional late innervation deficit/increased regional washout after PVI affecting the basal inferolateral wall (white arrow). Increasing SDS (summed defect score) but Stable H/M ratio.Back to article page
