Capsule Endoscopy in a Patient with an Implanted CCM System and an Implantable Defibrillator.

Wireless video capsule endoscopy (CE) is a modern diagnostic tool. Because of its use of digital radiofrequency, it is still relatively contraindicated in patients with implanted cardiac devices. We report the case of a patient with an Optimizer III system delivering cardiac contractility modulating signals (CCM) for heart failure therapy and an implantable cardioverter defibrillator (ICD) who underwent CE. No interferences between the devices were found.
