Cardiac resynchronization therapy (CRT) is recommended in international guidelines for patients with heart failure due to important left ventricular systolic dysfunction (or heart failure with reduced ejection fraction) and ventricular conduction tissue disease. Cardiac magnetic resonance (CMR) represents the most powerful imaging tool for dynamic assessment of the volumes and function of cardiac chambers but is rarely utilized in patients with CRT due to limitations on the device, programming and scanning. In this review, we explore the known utility of CMR in this cohort with discussion of the risks and potential benefits of scanning whilst CRT is active, including a practical strategy for conducting high quality scans safely. Our contention is that imaging in patients with CRT could be improved further by keeping resynchronization therapy active with resultant benefits on research and also patient outcomes.
心脏再同步治疗（CRT）被国际指南推荐用于左心室收缩功能障碍（或射血分数降低的心力衰竭）和心室传导组织疾病导致心力衰竭的患者。心脏磁共振（CMR）是评估心腔容积和功能的最强大的影像学工具，但由于设备、编程和扫描的限制，在 CRT 患者中很少使用。在这篇综述中，我们探讨了 CMR 在这一组患者中的已知用途，并讨论了在 CRT 激活时进行扫描的风险和潜在益处，包括安全进行高质量扫描的实用策略。我们认为，通过保持 CRT 的同步治疗，对研究和患者结局都有好处，从而可以进一步改善 CRT 患者的影像学检查。
