Ventricular tachycardia (VT) ablation is limited by modest acute and long-term success rates, in part due to the challenges in accurately identifying the arrhythmogenic substrate. The combination of multimodality imaging along with information from electroanatomic mapping allows for a more comprehensive assessment of the arrhythmogenic substrate which facilitates VT ablation, and the use of preprocedural imaging has been shown to improve long-term ablation outcomes. Beyond regional recognition of the arrhythmogenic substrate, advanced imaging techniques can be used to create tailored ablation strategies preprocedurally. This review will focus on how imaging can be used to guide ablation planning and execution with a focus on clinical applications aimed at improving the outcome of VT ablation procedures.
室性心动过速（VT）消融术的急性和长期成功率有限，部分原因是准确识别心律失常基质存在挑战。多模态成像与电生理标测信息相结合，可以更全面地评估心律失常基质，从而有助于 VT 消融术的开展，并且术前影像学的应用已被证明可以改善长期消融效果。除了对心律失常基质进行区域性识别外，还可以使用先进的成像技术在术前制定个体化的消融策略。本综述将重点介绍如何使用影像学来指导消融计划的制定和实施，重点关注旨在改善 VT 消融术效果的临床应用。
