Functional substrate mapping with a large-footprint lattice-tip catheter during VT ablation shows promising feasibility for improved outcomes in patients with abnormal scar tissue.
Is functional substrate mapping and ablation with a novel lattice-tip catheter feasible and effective in patients with ischemic cardiomyopathy and monomorphic ventricular tachycardia?
Functional substrate mapping and ablation using a novel lattice-tip catheter is feasible, providing high-quality near-field signals and high acute procedural success for ventricular tachycardia in ischemic cardiomyopathy.

Functional mapping refers to a variety of mapping approaches for ventricular tachycardia (VT) ablation that aim to reveal dynamic substrate changes related to conduction discontinuity within the abnormal scar tissue due to source-sink mismatch and nonuniform anisotropic propagation.1,2 Data regarding the feasibility of functional substrate mapping with a large-footprint lattice-tip catheter that allows both mapping and ablation with dual energy radiofrequency high-energy (RF) or pulsed field (PF) energy are missing.
