Follow-up

Immediate postoperative period

Key result

Extracardiac radiofrequency ablation induced electromagnetic interference that temporarily inhibited the implanted pulse generator and caused irregular pacing, but did not permanently damage it.

Overview

Transient EMI risk warrants vigilance near pacemakers; case report leaves open standardized perioperative protocols.

Structured PICO

Does extracardiac radiofrequency ablation cause electromagnetic interference or damage in patients with a permanent pacemaker?

P
Population
One male patient with a permanent dual-chamber pacemaker undergoing extracardiac radiofrequency ablation for a right adrenal metastasis.
E
Exposure
Extracardiac radiofrequency ablation (four 12-min ablations, max 200 W, 480 kHz) of a right adrenal metastasis.
O
Outcome
Pacemaker function and electromagnetic interference during and after radiofrequency ablation.safety

Extracardiac radiofrequency ablation in close proximity to a permanent pacemaker can cause significant but transient electromagnetic interference without permanently damaging the device.

Limitations

  • Limited information obtained from reported cases
  • Limited information from reported cases

Tong et al. (2004) conducted a case report in Right adrenal metastasis with permanent pacemaker (n=1). Extracardiac radiofrequency ablation was evaluated on Pacemaker function and electromagnetic interference. Extracardiac radiofrequency ablation induced electromagnetic interference that temporarily inhibited the implanted pulse generator and caused irregular pacing, but did not permanently damage it.
