Magnetic resonance imaging (MRI) has long been regarded a general contraindication in patients with cardiovascular implanted electronic devices such as cardiac pacemakers or cardioverter defibrillators (ICDs) due to the risk of severe complications and even deaths caused by interactions of the magnetic resonance (MR) surrounding and the electric devices. Over the last decade, a better understanding of the underlying mechanisms responsible for such potentially life-threatening complications as well as technical advances have allowed an increasing number of pacemaker and ICD patients to safely undergo MRI. This review lists the key findings from basic research and clinical trials over the last 20 years, and discusses the impact on current day clinical practice. With 'MR-conditional' devices being the new standard of care, MRI in pacemaker and ICD patients has been adopted to clinical routine today. However, specific precautions and specifications of these devices should be carefully followed if possible, to avoid patient risks which might appear with new MR technology and further increasing indications and patient numbers.
长期以来，磁共振成像（MRI）一直被视为患有心血管植入式电子设备（如心脏起搏器或心脏复律除颤器（ICD））患者的一般禁忌证，因为磁共振（MR）环境与电子设备之间的相互作用存在导致严重并发症甚至死亡的风险。在过去十年中，对导致此类潜在危及生命并发症的潜在机制的更好理解以及技术进步，使得越来越多的起搏器和ICD患者能够安全地接受MRI检查。本综述列出了过去20年基础研究和临床试验的主要发现，并讨论了其对当前临床实践的影响。随着“MR条件性”设备成为新的护理标准，起搏器和ICD患者的MRI检查如今已被纳入临床常规。然而，如果可能的话，应仔细遵循这些设备的特定预防措施和规范，以避免新的MR技术以及适应症和患者数量的进一步增加可能带来的患者风险。
