Background: More patients with cardiac implantable electrical devices (CIEDs) are presenting to
spine and pain practices for radiofrequency ablation (RFA) procedures for chronic pain. Although
the potential for electromagnetic interference (EMI) affecting CIED function is known with RFA
procedures, available guidelines do not specifically address CIED management for percutaneous RFA
for zygapophyseal (z-joint) joint pain, and thus physician practice may vary.
Objectives: To better understand current practices of physicians who perform RFA for chronic
z-joint pain with respect to management of CIEDs. Perioperative CIED management guidelines
are also reviewed to specifically address risk mitigation strategies for potential EMI created by
ambulatory percutaneous spine RFA procedures.
Study Design: Web-based provider survey and narrative review.
Setting: Multispecialty pain clinic, academic medical center.
Methods: A web-based survey was created using Research Electronic Data Capture (REDCap). A
survey link was provided via e-mail to active members of the Spine Intervention Society (SIS), American
Society of Regional Anesthesia and Pain Medicine, as well as distributed freely to community Pain
Physicians and any receptive academic departments of PM&R or Anesthesiology. The narrative
review summarizes pertinent case series, review articles, a SIS recommendation statement, and
multi-specialty peri-operative guidelines as they relate specifically to spine RFA procedures.
Results: A total of 197 clinicians participated in the survey from diverse clinical backgrounds,
including anesthesiology, physical medicine and rehabilitation, radiology, neurosurgery, and
neurology, with 81% reporting fellowship training. Survey responses indicate wide variability in
provider management of CIEDs before, during, and after RFA for z-joint pain. Respondents indicated
they would like more specific guidelines to aid in management and decision-making around
CIEDs and spine RFA procedures. Literature review yielded several practice guidelines related to
perioperative management of CIEDs, but no specific guideline for percutaneous spine RFA procedures.
However, combining the risk mitigation strategies provided in these guidelines, with interventional
pain physician clinical experience allows for reasonable management recommendations to aid in
decision-making.
Limitations: Although this manuscript can serve as a review of CIEDs and aid in management
decisions in patients with CIEDs, it is not a clinical practice guideline.
Conclusions: Practice patterns vary regarding CIED management in ambulatory spine RFA
procedures. CIED presence is not a contraindication for spine RFA but does increase the complexity
of a spine RFA procedure and necessitates some added precautions.
