Obesity and diabetes can lead to heart failure with preserved ejection fraction (HFpEF),
potentially because they both cause expansion and inflammation of epicardial adipose …

Background: The prevalence and significance of structural abnormalities in Brugada
syndrome (BrS) are still largely debated. Objectives: The authors investigated the …

Non-ischaemic cardiomyopathy (NICM) encompasses a heterogeneous group of disorders
that includes genetic, idiopathic, post viral and inflammatory cardiomyopathies. NICM is …

Introduction Microstructural abnormalities at the epicardium of the right ventricular outflow
tract (RVOT) may provide the arrhythmia substrate in Brugada syndrome (BrS). Endocardial …

Abstract Aims Bipolar electrogram (BiEGM)-based substrate maps are heavily influenced by
direction of a wavefront to the mapping bipole. In this study, we evaluate high-resolution …

Aims Unipolar voltage (UV) mapping is increasingly used for guiding ablative therapy of
atrial fibrillation (AF) as unipolar electrograms (U-EGMs) are independent of electrode …

Objectives This study sought to investigate the value of electroanatomical voltage mapping
(EAVM) to distinguish cardiac sarcoidosis (CS) from arrhythmogenic right ventricular …

Introduction Electronatomical mapping allows direct and accurate visualization of
myocardial abnormalities. This study investigated whether high‐density endocardial bipolar …

Aims Endocardial unipolar and bipolar voltage mapping (UVM/BVM) of the right ventricle
(RV) are used for transmural substrate delineation. However, far-field electrograms (EGMs) …

Background Myxomatous mitral valve prolapse (MVP) and mitral‐annular disjunction
(Barlow disease) are at‐risk for ventricular arrhythmias (VA). Fibrosis involving the papillary …
