Heart Valves and MRI Testing

If you are told you need to have an MRI (magnetic resonance image) scan, tell the doctor you have an artificial heart valve and show your patient device ID card, which contains important information about how to perform an MRI scan safely with your valve.

Nonclinical testing has demonstrated that St. Jude Medical™ heart valves and repair devices are MR Conditional. They can be scanned safely under the following conditions:

  • Static magnetic field of 1.5 Tesla (1.5T) or 3.0 Tesla (3.0T)
  • Maximum spatial gradient field less than or equal to 3,000 Gauss/cm (30T/m)
  • Normal Operating Mode: Maximum whole-body averaged specific absorption rate (SAR) of:
    • 2.0 W/kg for 15 minutes of scanning in Normal Operating Mode at 1.5T
    • 2.0 W/kg for 15 minutes of scanning in Normal Operating Mode at 3.0T

If you have questions or concerns about this and other diagnostic tests and your heart valve, please talk to your doctor. It is wise to provide your doctor with the information outlined above about MRI testing and your heart valve. We recommend that you share one of the following letters with your doctor and health care team:
