Key result
Integrating cardiac CT with EAM during VT ablation is linked to ~41% lower 1-year recurrence.
Why the study?
Catheter ablation for VT secondary to IHD is limited by procedure complexity and safety, leading to investigation of whether integrating pre-procedural cardiac CT into EAM improves ablation outcomes.
Does integrating pre-procedural cardiac CT with electro-anatomical mapping reduce VT recurrence and ICD shocks in patients with ischaemic heart disease undergoing catheter ablation?
Cohort (n=79)
No
Does integrating pre-procedural cardiac CT with electro-anatomical mapping reduce VT recurrence and ICD shocks in patients with ischaemic heart disease undergoing catheter ablation?
Integrating pre-procedural cardiac CT with electro-anatomical mapping during VT ablation in patients with ischemic heart disease reduces ablation time and significantly lowers 1-year VT recurrence and ICD shocks.
Answers are grounded in this paper and cite their sources.
CT integration was associated with lower VT recurrence in IHD; leaves open need for randomized confirmation before practice change.

Sammut et al. (2026) conducted a cohort in Ventricular tachycardia secondary to ischaemic heart disease (n=79). Integration of pre-procedural cardiac CT with electro-anatomical mapping vs. No CT integration was evaluated on Ventricular tachycardia recurrence at 1 year (p=0.024). Integrating pre-procedural cardiac CT with electro-anatomical mapping during VT ablation in patients with ischaemic heart disease reduced 1-year VT recurrence (26% vs 44%, p=0.024).
