Magnetic resonance imaging in a patient with cardiac resynchronization therapy‐defibrillator and two abandoned leads

For secondary prophylaxis after ventricular fibrillation and ischemic heart disease, a biventricular defibrillator was implanted in 2010. Based on an individual benefit–risk assessment, the decision to perform cMRI (Philips Ingenia 1.5 T-MR-system) under constant monitoring was made in consensus with the patient after being informed about the limited clinical experience with MRI in patients with CRT-D devices and abandoned leads. 1–3 Device interrogation was performed prior to and immediately after MRI, during the MRI the device was programmed in the specific MRI mode (Enable MRI protection, DOO 80). The patient did not report any palpitations, discomfort, heating, or sensations during or after the exam, there were no abnormal vital signs or arrhythmias during monitoring (ECG monitoring, O2 saturation monitoring, external defibrillator close by, CPR trained staff on site) and no device malfunction was detected, that is, no change of pacing rate, no change in battery voltage, no power-on reset events and no changes of CRT-D programming, and no change in lead parameters.
