CONCLUSION

This study shows that the SJM Tendril MRI lead heats significantly less than the MDT CapSureFix MRI lead, and thus better prevents MRI-induced cardiac tissue damage. The heating of the standard SJM Tendril 1888TC lead was found to be comparable to that of the MDT CapSureFix MRI lead.

BACKGROUND

RF heating at the electrodes of pacemaker leads during MRI scans can cause myocardial tissue damage around the electrodes resulting in device pacing and sensing malfunctions. The conductors of an implantable cardiac lead flow induced currents that can cause excessive cardiac tissue heating. This study evaluated RF heating generated by 2 conditionally MRI safe systems, Medtronic (MDT) MRI SureScan™ and St. Jude Medical (SJM) Accent MRI™.
