Doses from ionising radiation in paediatric cardiac catheterisations in Norway 1975–2021

Susmita Afroz, Bjørn Helge Østerås, U S Thevathas, Marianna Meo et autres

Abstract Paediatric patients with congenital heart disease often undergo cardiac catheterisation procedures and are exposed to considerable ionising radiation early in life. This study aimed to develop a method for estimating the dose area product (P KA) from paediatric cardiac catheterisation procedures …

Automatic identification of ablation targets in persistent atrial fibrillation: Initial experience with a new mapping tool

Decebal Gabriel Lațcu, Bogdan Enache, Chloe Lerebours, Sofia Milanese et autres

INTRODUCTION: Strategies beyond pulmonary vein isolation (PVI) in persistent atrial fibrillation (persAF) are debated. A novel mapping tool provides algorithmic detection of ablation targets based on electrogram (EGM) properties specific to stable localized rotational activations. METHODS: The mapping tool was used on …

Editorial: Women in Cardiac Electrophysiology: 2022

Marianna Meo, Stefanie Fenske, Rasheda A. Chowdhury

1 IntroductionDespite the talent shortage and the increasing demand of human workforce in the fields of science, technology, engineering, and mathematics (STEM), the role of women in driving the scientific progress and developing novel technologies remains marginal, as confirmed by the UNESCO …

Editorial: Cardiovascular neuromodulation: mechanisms and therapies

Deborah Hunt, Marco Mongillo, Marianna Meo, Tania Zaglia et autres

High cardiovascular disease (CVDs) prevalence is projected to impact a large population across the world [1]. Future therapeutic development efforts should take these estimates into account and provide new treatment modalities. Modern neuromodulation therapies are an emerging non-pharmacological approach for the treatment …

Relation of surface T-wave to vulnerability to ventricular fibrillation in explanted structurally normal hearts

Marianna Meo, Pietro Bonizzi, Laura R. Bear, Matthijs J M Cluitmans et autres

Introduction: Body surface characterization of repolarization gradient substrates for ventricular fibrillation (VF) is still poor.We investigated if VF propensity can be assessed from surface T-wave in an ex-vivo model of purely electrical repolarization dispersion.Methods: To create repolarization gradients, dofetilide and/or pinacidil were …

Abstract 16495: Activation of Notch Signaling in the Heart Promotes Electrical Disturbances

Emanuele Pizzo, Daniel O. Cervantes, Martina Comelli, Marianna Meo et autres

Notch1 receptor signaling is active in the heart during embryonic development, is progressively silenced after birth, and it is partly restored in the adult myocardium following ischemic damage, a condition characterized by occurrence of arrhythmias. We previously reported that inducible overexpression of …

Abstract 16545: Sinus Rhythm Dynamics and Ventricular Ectopy in an Experimental Model of Aging

Martina Comelli, Emanuele Pizzo, Marianna Meo, Daniel O. Cervantes et autres

Aging is coupled with alterations of heart rate and heart rate variability (HRV), together with increased incidence of arrhythmias and sudden cardiac death. But whether changes of sinus rhythm properties of the aged heart correlate with enhanced occurrence of ventricular ectopic discharge …

Insights Into the Spatiotemporal Patterns of Complexity of Ventricular Fibrillation by Multilead Analysis of Body Surface Potential Maps

Marianna Meo, Arnaud Denis, Frédéric Sacher, Josselin Duchâteau et autres

Background Ventricular fibrillation (VF) is the main cause of sudden cardiac death, but its mechanisms are still unclear. We propose a noninvasive approach to describe the progression of VF complexity from body surface potential maps (BSPMs). Methods We mapped 252 VF episodes …
