MRI in patients with cardiac implantable electronic devices is associated with rare or clinically insignificant adverse events across both MR nonconditional and conditional devices.
Is MRI safe to perform in patients with cardiac implantable electronic devices?
This review highlights that MRI is generally safe for patients with cardiac implantable electronic devices, including legacy nonconditional devices, with rare or clinically insignificant adverse events.
Indications for MRI have grown considerably in recent years. However, many patients with cardiac implantable electronic devices are denied imaging due to physician misinterpretation of the risks associated with MRI. This review discusses the theoretical basis for the perceived risk by exploring preclinical literature. It then presents a detailed examination of the true rates of adverse events in clinical studies across both MR nonconditional (legacy) and MR conditional devices. Indeed, many of these adverse events are rare, nonexistent, and/or clinically insignificant in the wealth of published data. The authors then address image quality and the constituents of a safety checklist that institutions should consider when performing MRI in patients with a cardiac implantable electronic device. Lastly, the authors conclude with an overview of future directions for advancement in the field.
Muthalaly et al. (Tue,) conducted a review in Cardiac implantable electronic devices. MRI was evaluated on Adverse events. MRI in patients with cardiac implantable electronic devices is associated with rare or clinically insignificant adverse events across both MR nonconditional and conditional devices.
