[Cardiac magnetic resonance with a MRI compatible pacemaker]

Abstract

Patients with cardiac implantable electronic devices are usually excluded from MRI examinations due to contraindication for MRI. The MRI-conditional pacemaker system may allow the benefits of MRI (system 1.5T) to be more accessible to pacemaker patients. A 62-year-old man was admitted with acute coronary syndrome and atrial fibrillation. A conventional angiography showed normal coronaries. A cardiac cardioversion revealed a significant sinus node dysfunction and a magnetic resonance imaging (MRI) compatible dual chamber system was implanted. At 6-week follow-up, a cardiac MRI revealed a typical anterior myocardial infarction with diagnostic quality images despite pacemaker. This is one of the first reports of cardiovascular MRI in a patient with MRI-conditional pacing system.
