Safety of the colonoscope magnetic imaging device (ScopeGuide) in patients with implantable cardiac devices.
Use of the colonoscope magnetic imaging device (ScopeGuide, Olympus Medical Systems, Tokyo, Japan) is currently contraindicated by the manufacturer for patients with implantable cardiac devices, a group of patients that is increasing annually along with the number of colonoscopies performed in the era of colorectal cancer screening. This is the first study to examine the safety of ScopeGuide in patients with permanent pacemakers, implantable cardioverter defibrillators, and cardiac resynchronization therapy. ⋯ ScopeGuide does not appear to cause interference or change in settings and is therefore likely to be safe for use in patients with implantable cardiac devices.
