“…There has been a growing interest in assessing the safety and feasibility of VCE in this population that was reflected by the increasing number of clinical studies over the recent years. Theoretically, electromagnetic interference between both devices is possible and its impact on either of the devices is yet to be determined [4]. However, interference with the cardiac devices is not an expected event physically, given that the signal magnitude from the capsule recorder is too low to interfere with PPMs/ICDs, in addition to several safety mechanisms that isolate most of the manufactured pacemakers/defibrillators from their surroundings such as the hermetically sealed titanium housing around the device, the bipolar mode programming, and the provision of filters in the amplifier [4].…”

“…The implantation of PPM and ICD for the treatment of brady- and tachy-arrhythmia has increased significantly over the last 30 years [4]. Likewise, there has been an increase in the development and use of technology that emits electromagnetic radiations that may disturb the behavior of cardiac implantable electronic devices (CIED) with potential harmful consequences.…”

“…Likewise, there has been an increase in the development and use of technology that emits electromagnetic radiations that may disturb the behavior of cardiac implantable electronic devices (CIED) with potential harmful consequences. Because one of the most essential components of CIED function is accurate sensing of intrinsic cardiac potentials, any interference by nonphysiologic sources may cause the system to interpret such interference as cardiac in nature [4]. This noise sensing can have drastic adverse clinical consequences, such as the failure to pace when needed, or the triggering of ICD therapies due to inappropriate identification of noise as ventricular tachycardia or ventricular fibrillation [4].…”

“…This interference between two separate electronic devices is called electromagnetic interference (EMI). The sources of EMI can be related to every-day-use devices like cellular phones and metal detectors [4] or can be iatrogenic like radiation therapy, electrocautery, transcutaneous electric nerve stimulation, electroconvulsive therapy, and magnetic resonance imaging [4]. Video capsule generates an electromagnetic field and theoretically can be a source of EMI with implantable cardiac devices having possible consequences on patients.…”

Background. To date, video capsule endoscopy (VCE) is still contraindicated by the FDA and the main manufacturers of Cardiac Implantable Electronic Devices (CIED) in patients with CIED, given a theoretical electromagnetic interference and possible device malfunction. Objectives. The objective of this study was to assess the safety profile and efficacy of VCE in patients with implantable cardiac devices through analyzing the risk of mutual interference. Methods. A systematic review of PubMed, Web of Science, and Embase databases was conducted. Peer-reviewed original articles, published in the English language and containing “capsule endoscopy” AND “pacemaker”, “defibrillator” OR “left ventricular assist device” as keywords, were selected. Studies performed in vitro, isolated case reports, and abstracts/posters were excluded. Results. A total of 735 VCE procedures were performed in patients with cardiac devices in various clinical settings. Cardiac events were not seen in any case. Interference on capsule images transmission was noted in 5 cases (left ventricular assist device (LVAD)) where few images were lost when the capsule was closest to the device. Finally, interference between capsule and telemetry leads was noted in 6 cases (4 Permanent Pacemakers (PPM), 2 Implantable Cardioverter-Defibrillator (ICD)) leading to image artifacts. Discussion. Adverse cardiac events were not seen in any study. Loss of images occurred when the VCE was in proximity to the device (only with LVAD) or after telemetry leads installation without affecting the completion rate and diagnostic yield of VCE. Conclusion. VCE is safe and remains efficient in patients with cardiac devices. If cardiac monitoring is required, wired systems are preferable.
