Leadless Cardiac Pacemaker

Safety: Conditional

Risks: Thermal, Arrhythmia, Device Malfunction

Conditions:

Identify type of leadless pacemaker to determine maximum static field strength
- Medtronic Micra Pacemaker
  - Static field strength up to and including 3T
- St. Jude Nanostim Leadless Pacemaker
  - Static field strength up to and including 1.5T
Requires cardiologist programming before and after MRI
Do not bring controller into MRI scanner

Comments:

Also known as Micra pacemaker or Nanostim pacemaker
Not to be confused with Implanted Cardiac Event Monitor (Loop Recorder), which may be mistaken for Leadless Pacemaker on radiograph
For scheduling of cases, please see Scheduling for Patients with MRI Conditional Devices.
Currently these devices are only imaged on the Montefiore Moses campus

Bottom line: MRI permissible within designated field strengths. Requires radiologist approval and scheduling.
