Sudden cardiac death (SCD) can be effectively prevented with the use of implantable cardioverter-defibrillator (ICD). Current guidelines advocate an ICD for primary prevention in the presence of an left ventricular ejection fraction (LVEF) ≤ 35%. The majority of individuals that experience SCD, however, have an LVEF > 35%. Multimodality cardiac imaging has the ability to visualize the three factors responsible for arrhythmia-mediated SCD, namely substrate, trigger and modulator. Advances in cardiac imaging techniques have allowed improved SCD risk stratification, especially in the group of patients with an LVEF > 35%. However, clinical integration of cardiac imaging for SCD risk stratification will require more comparative data between modalities and parameters, as well as evidence of an impact on outcomes. The current review represents an update on the use of multimodality imaging techniques for SCD risk stratification.
心脏性猝死 (SCD) 可以通过植入式心脏复律除颤器 (ICD) 的使用得到有效预防。目前的指南主张在左心室射血分数 (LVEF) ≤ 35% 的情况下将 ICD 用于一级预防。然而，大多数经历 SCD 的人 LVEF > 35%。多模态心脏成像能够可视化导致心律失常介导的 SCD 的三个因素，即基质、触发和调节剂。心脏成像技术的进步使 SCD 风险分层得到了改善，特别是在 LVEF > 35%的患者群体中。然而，心脏成像用于 SCD 风险分层的临床整合将需要更多模态和参数之间的比较数据，以及对结果产生影响的证据。本综述代表了多模态成像技术在 SCD 风险分层中的应用的最新进展。
