An MRgFUS ablation treatment of lumbar facet joints in a patient with a traditional MRI non-conditional pacemaker was completed. A risk-benefit analysis by a coordinated multi-disciplinary team prior to this treatment was performed to account for the risks associated with traditional MRI non-conditional pacemaker. The treatment was successfully performed as per our institution established cardiac implanted electronic device (CIED) MRI practice and the patient had no adverse cardiac event during or following this procedure. By careful use of our institutional CIED MR-practice guidelines, we demonstrated that such treatments can be safely achieved for patients with CIEDs on a case-by-case basis.
