Significant improvement of cardiac sympathetic function following cardiac support device implantation: illustration by 123I-MIBG scintigraphy

Cardiac support device implantation is a new and promising therapy for refractory heart failure. If functional and echocardiographic modifications have largely been reported following this procedure, there is a paucity of information in the clinical setting about cellular abnormalities modifications during the 'reverse remodeling' process. We report for the first time a clinical measurement of cardiac sympathetic function using 123I-MIBG scintigraphy following cardiac support device implantation.
