High resolution images and 3D movie of the heart using a radiotracer that targets sympathetic nerve activity.
These images demonstrate diffuse sympathetic activity in left ventricle and focal activity in areas of the atria that represent ganglionic plexi.
Recent data suggests a potential benefit of ablation of these ganglionic plexi with RF or local injection of botox when used in combination with pulmonary vein isolation for treatment of recurrent A-fib.
