073_16284-H5 Visualization of Left Atrial Sympathetic Innervation Activity and the Effect of Catheter Ablation on Activity Patterns in Patients With Atrial Fibrillation

A novel cardiac gamma camera utilises the radiopharmaceutical Iodine-123 Meta- iodobenzylguanidine (123I –m IBG) to visualise cardiac sympathetic innervation. Physiologic uptake of 123I  –m IBG provides anatomical quantification of autonomic nervous system (ANS) structures, with discrete uptake
