MRIs and implantable device safety: heartwire collection

MRIs and implantable device safety

Magnetic resonance imaging tests are increasingly being used for diagnosing forms of heart disease and for a wide range of other ailments, at the same time that more and more people are receiving ICDs and pacemakers. Just what are the risks to patients and to devices themselves?

MRI of implantable devices: Do we need safer devices, safer scanning procedures, or both?

Mar 18, 2010 14:30 EDT

The advent of new "MRI-safe" devices does not imply that MRI cannot be performed safely on older devices, according to the leaders of the MagnaSafe registry.

UPDATED WITH COMMENTARY // Researchers have developed a new protocol for the safe MRI of patients with cardiovascular implantable devices.

Arrhythmia/EP

No complications, no overheating with MRI-compatible pacemaker and leads

2 COMMENTS - May 14, 2009 16:40 EDT

UPDATED // Patients with pacemakers are not allowed in an MR scanner because of concerns about induced arrhythmias and overheated leads, but this study showed no complications and no changes in temperature at the tip of the lead. Investigators say this is good news, considering the growing number of pacemaker-implanted patients who require an MRI scan.

New statement on safety of MRI with CV devices

Nov 30, 2007 15:45 EST

The AHA has issued a scientific statement on the safety of MRI in patients with cardiovascular devices. For most devices, if there is a good clinical indication for MRI, the benefits of scanning outweigh the risks, the lead author says. The exceptions to these are pacemakers and ICDs—patients with such devices should receive MRIs only if needed and only then in expert centers, he says. (Levine GN et al. Circulation; published online before print November 19, 2007.)

MRI may be safe for patients with some types of pacemakers, ICDs

Aug 4, 2004 15:30 EDT

New in vitro and animal testing suggests that MRI might be safely offered to patients with most types of pacemakers and ICD models manufactured after the year 2000. Such devices are currently considered a contraindication for MRI. (Roguin A et al. Circulation 2004; 110:475-482.)
