Ventricular arrhythmias are an important cause of morbidity and mortality and come in a
variety of forms, from single premature ventricular complexes to sustained ventricular …

Excessive trabeculation, often referred to as “noncompacted” myocardium, has been
described at all ages, from the fetus to the adult. Current evidence for myocardial …

There is increasing evidence regarding the prevalence of genetic cardiomyopathies, for
which arrhythmias may be the first presentation. Ventricular and atrial arrhythmias …

Abstract Background and Aims This study aimed to histologically validate atrial structural
remodelling associated with atrial fibrillation. Methods and results Patients undergoing atrial …

Catheter ablation is nowadays considered the treatment of choice for numerous cardiac
arrhythmias in different clinical scenarios. Fluoroscopy has traditionally been the primary …

Background: The accuracy of ECG imaging (ECGI) in structural heart disease remains
uncertain. This study aimed to provide a detailed comparison of ECGI and contact-mapping …

Objectives: This study sought to evaluate the value of combined electrogram (EGM)
information provided by simultaneous mapping using micro-and conventional electrodes in …

Catheter ablation is being increasingly performed as adjunctive treatment to prevent
recurrent implantable cardioverter-defibrillator therapies in patients with nonischemic …

Introduction The assessment of the ventricular myocardial substrate critically depends on the
size of mapping electrodes, their orientation with respect to wavefront propagation, and …

Accurate substrate characterisation may improve the evolving understanding and treatment
of cardiac arrhythmias. During substrate-based ablation techniques, wide practice variations …
