Computed Tomography–Defined Ridges and Functional Mapping in Ablation of Postinfarction Ventricular Tachycardia | JACC: Clinical Electrophysiology
In this episode, Frank Marchlinski, MD, Deputy Editor of JACC: Clinical Electrophysiology, discusses a study evaluating how CT-defined myocardial ridges and functional mapping can be combined to identify critical ablation targets in post-infarction ventricular tachycardia. The investigators found that VT target sites frequently localized to CT-defined ridges, particularly those associated with primary deceleration zones, suggesting that functional mapping can help distinguish active arrhythmogenic ridges from inactive ones and support more targeted VT ablation.
