| Studies have shown that magnetic resonance imaging (MRI) does not have clinically important effects on the device parameters of non–MRI-conditional implantable cardioverter-defibrillators (ICDs). However, data on non–MRI-conditional ICD detection and treatment of arrhythmias after MRI are limited. | |
During a median follow-up of 2.2 years from MRI to latest available ICD interrogation before generator or lead exchange in 536 patients, 4177 arrhythmia episodes were detected, and 97 patients received ICD shocks. Sixty-one patients (10% of total) had 130 spontaneous ventricular tachycardia or fibrillation events terminated by ICD shocks. A total of 210 patients (33% of total) are known to have died (median, 1.7 years from MRI to death); 3 had cardiac arrhythmia deaths where shocks were indicated without direct evidence of device dysfunction.
Conclusion:Non–MRI-conditional ICDs appropriately treated detected tachyarrhythmias after MRI. No serious adverse effects on device function were reported after MRI. |
