Optimal healing of damaged tissue following myocardial infarction (MI) requires a
coordinated cellular response that can be divided into three phases: inflammatory …

Substrate mapping was developed to treat poorly tolerated infarct-related ventricular
tachycardias (VTs). This concept was based on 30-year-old data derived from surgical and …

Abbreviations: 3D, three-dimensional; AF, atrial fibrillation; AP, accessory pathway; ARVC,
arrhythmogenic right ventricular cardiomyopathy; AT, atrial tachycardia; AVB, atrioventricular …

Background Pulsed field ablation (PFA) leads to cell death by irreversible electroporation.
There are limited data about PFA lesion characteristics in the ventricle, particularly in the …

Background: In vivo description of ventricular tachycardia (VT) circuits is limited by
insufficient spatiotemporal resolution. We used a novel high-resolution mapping technology …

In the chronic stage of myocardial infarction, a significant number of patients develop life-
threatening ventricular tachycardias (VT) due to the arrhythmogenic nature of the remodeled …

Background—Mapping resolution is influenced by electrode size and interelectrode
spacing. The aims of this study were to establish normal electrogram criteria for 1-mm …

Objectives: In this study, the scientific objective was to characterize the electrophysiological
substrate of the ventricular tachycardia (VT) isthmus during sinus rhythm. Background: The …

Objectives: The authors conducted a multicenter study of decrement-evoked potential
(DEEP)–based functional ventricular tachycardia (VT) substrate modification to evaluate if …

Objectives: This study sought to determine whether combined endocardial-epicardial (endo-
epi) ablation was superior to endocardial only ablation in patients with scar-related …
