MRI conditional pacemakers provide a widely applicable and satisfactory solution to allow magnetic resonance imaging in patients with cardiac implantable electronic devices.
This review summarizes the rationale, development, and clinical experience of MRI conditional pacemakers, which provide a widely applicable solution for CIED patients needing MRI.
Pacemakers and other cardiac implantable electronic devices (CIEDs) have long been considered an absolute contraindication to magnetic resonance imaging (MRI), a crucial and growing imaging modality. In the last 20 years, protocols have been developed to allow MR scanning of CIED patients with a low complication rate. However, this practice has remained limited to a relatively small number of centers, and many pacemaker patients continue to be denied access to clinically indicated imaging. The introduction of MRI conditional pacemakers has provided a widely applicable and satisfactory solution to this problem. Here, the interactions of pacemakers with the MR environment, the results of MR scanning in patients with conventional CIEDs, the development and clinical experience with MRI conditional devices, and future directions are reviewed.
Cronin et al. (Sat,) conducted a review in Patients with pacemakers and other cardiac implantable electronic devices requiring MRI. MRI conditional pacemakers vs. Conventional CIEDs was evaluated. MRI conditional pacemakers provide a widely applicable and satisfactory solution to allow magnetic resonance imaging in patients with cardiac implantable electronic devices.
