Why the study?

Does CT-derived scar topography identify critical ablation sites in postinfarction ventricular tachycardia?

Key Points

To evaluate the correlation between computed tomography-derived wall thickness measurements of scar topography and critical catheter ablation sites in patients with postinfarction ventricular tachycardia.
Measured myocardial wall thickness using computed tomography (CT) to map postinfarction scar topography.
Assessed anatomical ridges of myocardial tissue within scar areas in relation to critical ventricular tachycardia circuits.
Computed tomography wall thickness assessment successfully identifies distinct ridges of surviving myocardial tissue within scar zones.
Tissue ridges frequently correspond to critical channels sustaining ventricular tachycardia and represent appropriate target sites for ablation.

Implication

CT wall thickness mapping may refine ablation targets in postinfarction VT; extends scar imaging for substrate-guided therapy.

Abstract

WT measured by CT identifies ridges of myocardial tissue that often are critical for postinfarction VT and that can be appropriate target sites for ablation.
