CONGRESS ABSTRACT

Background: Very-high-power-short duration (vHPSD) catheters are associated with less irrigation fluid load than standard (STD RF) ablation catheters. However, the impact of this fluid reduction on biomarkers in pulmonary vein isolation (PVI) for atrial fibrillation (AF) remains unknown. Methods and aim:  Biomarkers of heart failure, myocardial injury, and systemic…

A 74-year-old woman with a history of hypertension, diabetes, and ischemic heart disease was admitted to the hospital following the acute onset of palpitations. She had an ICD implanted 5 years earlier for primary prevention of sudden cardiac death due to ischemic cardiomyopathy with reduced left ventricular ejection fraction…

Background Pulsed field ablation (PFA) represents a significant improvement in the field of atrial fibrillation (AF) ablation. Nonetheless, PFA by using standard procedural protocol showed a similar efficacy as compared with thermal ablation. The aim of this study was to verify whether the systematic use of high-density (HD) mapping…

Introduction Premature ventricular contractions (PVCs) are frequently benign. However, a high arrhythmic burden can lead to the deterioration of left ventricular systolic function, resulting in newly developed cardiomyopathy or worsening of pre-existing cardiopathy. 2022 ESC guidelines for the management of ventricular arrhythmias recommend catheter ablation as class I treatment…

Background: Cardioneuroablation is conceivable for functional bradyarrhythmias caused by a dysregulation of the autonomic nervous system. Cardioneuroablation is an ablation technique that targets epicardial ganglionic plexi to reduce syncope burden and avoid pacemaker implantation in patients with vasovagal syncope and functional forms of sinus node dysfunction and atrioventricular block. The ergometric…

Background: Atrioventricular (AV) junctional ablation is commonly performed to treat refractory arrhythmias by disrupting AV conduction. The procedure traditionally targets either the site with the earliest His bundle potential or the most prominent His potential. However, this could lead to a proarrhythmic risk linked to QT interval prolongation and…
