Dispositivos cardíacos implantables y uso de resonancia magnética

The use of magnetic resonance imaging (MRI) in different areas of medicine has expanded significantly and nume - rous procedures are indicated daily. The fact that resonators could interact with some objects has historically led to patients with cardiac devices being denied an MRI on the understanding that they suppose an absolute contraindica - tion. Advances in device technology and the increasing evidence have changed this concept. We intend to review the mechanisms by which an implantable device could interact with the resonator and the clinical implications that this could have if any. Most patients will be able to undergo these studies, but to determine the safety of performing an MRI it is important to know the characteristics and specific type of implanted device. Finally, we provide key points and algorithms to take into account for these patients.
