CONGRESS ABSTRACT

Aims: A standardized sedation protocol for pulsed-field ablation (PFA) of atrial fibrillation (AF) through irreversible cellular electroporation has not been well established. We report our experience of a protocol for deep sedation with propofol maintaining spontaneous respiration during the PFA of AF. Bispectral index Monitoring System (BIS) is a…

Introduction Slow pathway ablation is currently the target for AV nodal reentrant tachycardia (AVNRT) with a high success rate of almost 100% and 0.5% to 2% risk of II- to III-degree AV block. Kock triangle (KT) mapping is helpful to define the fast pathway location, to find out its…

35-year-old male, active smoker, presented with recurrent episodes of palpitations. EKG showed sinus rhythm without pre-excitation or conduction disturbances. Ambulatory ECG recordings documented regular narrow QRS tachycardia with a short RP interval, consistent with supraventricular tachycardia. No structural heart disease and was referred for electrophysiological study and ablation. Noninvasive…

40-year-old male, no major cardiovascular risk factors, regular sports activity reported recurrent palpitations. In 2021, during excercise, he experienced palpitations associated with presyncope which resolved spontaneously, ECG revealed a short PR interval and delta wave, suggestive of a postero-septal accessory pathway. Exercise stress test induced a short episode of…

Background: Transcatheter ablation (TCA) is an established therapy for atrial fibrillation (AF), but the influence of age on procedural safety and early efficacy remains uncertain, especially in real-world practice. Objective: To determine the impact of age on early procedural safety and arrhythmic outcomes after TCA for AF in an…

Background: Radiofrequency ablation (RFA) with pulmonary vein isolation (PVI) represents a cornerstone of atrial fibrillation (AF) treatment. Persistent conduction across the carina requires extensive additional ablation. Combining bipolar and unipolar voltage CARTO maps and applying voltage thresholds [Fig.1], our group observed areas with discrete negative potentials in the carina…

Background Pulsed field ablation (PFA) is a novel non-thermal ablative modality. Data about periprocedural time comparison between PFA and radiofrequency ablation (RFA) of atrial fibrillation (AF) are lacking. Purpose We would assess if PFA compared to RFA could have an impact on procedural organization and workflow of AF ablation,…
