Effect of Microwave Prostate Therapy on St. Jude Medical Implantable Cardiac Rhythm Devices

Background

Transurethral microwave therapy (TUMT) uses microwave heat to shrink excess prostate tissue. Microwave prostate therapy systems are designed to deliver highly localized and controlled doses of microwave energy specifically to prevent thermal damage to tissues surrounding the prostate. Pacemakers and implantable cardioverter defibrillators (ICDs) are usually implanted in the pectoral region, so any energy that is delivered to the prostate is attenuated by the patient’s body to such a degree that damage to or reprogramming of the pacemaker or ICD is not likely.

Based on information from two manufacturers (Targis™ and Prostratron®) we would not anticipate any damage or reprogramming of the ICD or pacemaker due to microwave prostate therapy. To date, St. Jude Medical has had no reports of any adverse interactions of either of these systems with any of our ICDs or pacemakers. Literature review on this topic also showed a small sample study of patients with pacemakers and ICDs who received this treatment without any adverse interaction or programming changes to the device.
