Key result
Multimodal imaging refines non-ischaemic cardiomyopathy diagnosis and optimizes ventricular tachycardia ablation planning.
Why the study?
The heterogeneous nature of NICM aetiologies and VT substrates affects long-term ablation outcomes, and multimodal imaging has improved diagnosis and ablation strategies in this population.
Multimodal imaging aids in the accurate diagnosis of NICM subtypes and improves VT ablation strategies through better substrate characterization and procedural planning.
Multimodal imaging may refine substrate mapping for VT ablation in heterogeneous NICM; leaves open prospective outcome impact.
Catheter ablation is an effective treatment option for ventricular tachycardia (VT) in patients with non-ischaemic cardiomyopathy (NICM). The heterogeneous nature of NICM aetiologies and VT substrate in patients with NICM play a role in long-term ablation outcomes in this population. Over the past decades, more precise identification of NICM aetiologies and better characterisation of various substrates have been made. Application of multimodal imaging has greatly contributed to the accurate diagnosis of NICM subtypes and improved VT ablation strategies. This article summarises the current knowledge of multimodal imaging used in the characterisation of non-ischaemic NICM substrates, procedural planning and image integration for the optimisation of VT ablation.
