Clinical TrialCardiac troponin T in patients with cardiac implantable electronic devices undergoing magnetic resonance imaging.
Magnetic resonance imaging (MRI) has been safely performed in many patients with cardiac implantable electronic devices (CIEDs) using institution-specific protocols. A potential risk of MRI is myocardial heating and cardiac injury, which might be detectable with cardiac Troponin (cTn). We evaluated this in patients with CIEDs undergoing MRI. ⋯ There are very few situations where myocardial injury as detected by cTnT in patients undergoing MRI with CIEDs could be detected. No adverse clinical events or functional changes of the device were noted, even in those with increases in cTnT. Our experience supports that MRI can be performed safely for appropriately selected patients under close clinical observation. Proactive monitoring with the present iteration of cardiac biomarkers appears to be of limited utility, but prospective monitoring with high sensitivity assays may be able to detect subclinical myocardial damage.
