Update on Cardiovascular Implantable Electronic Devices for Anesthesiologists

With the advent of “wireless” endocardial pacing, the subcutaneous implantable cardioverter defibrillator, and leadless pacemakers comes an added layer of complexity to the perioperative management of cardiovascular implantable electronic devices (CIED). Since no formal recommendations currently exist for these new CIED technologies, preoperative identification of these devices, understanding their functionality, and developing an individualized perioperative management plan are imperative for the anesthesiologist. The following review is intended to provide the background information required to devise a successful perioperative management strategy for newer CIEDs.
