Multipath joint ablation strategy for focal atrial tachycardia originating from patent foramen ovale: a case report.

Front Cardiovasc Med

January 2025

Key Laboratory of Birth Defects and Related Diseases of Women and Children of MOE, Department of Pediatrics, West China Second University Hospital, Sichuan University, Chengdu, Sichuan, China.

Introduction: Focal atrial tachycardia (FAT) is predominant in the pediatric population. Recent research has identified cases of sustained FAT originating from the interatrial septum (IAS); a subset of cases presents a unique challenge, with foci originating from the peri-patent foramen ovale (peri-PFO), requiring specialized management during catheter ablation. Here, we present a rare case of peri-PFO-associated FAT that resulted in tachycardia-related cardiomyopathy and propose a comprehensive multipath joint strategy for the successful treatment of PFO-associated FAT.

Unlabelled: Corrected transposition of the great arteries (c-TGA) is a congenital abnormality characterized by atrioventricular (AV) and ventriculoarterial discordance, associated with early and late-onset conduction disturbances. We report the case of a c-TGA patient affected by congenital complete AV block, with right ventricular lead malfunction with prolonged dwell time and two abandoned leads. He underwent leadless VDD pacemaker implantation at an unusual site (i.

Background: The Hispanic/Latino population is not uniform. Prevalence and clinical outcomes of cardiac arrhythmias in ethnic background subgroups are variable, but the reasons for differences are unclear. Vectorcardiographic Global Electrical Heterogeneity (GEH) has been shown to be associated with adverse cardiovascular outcomes.

Our study evaluated the efficacy and feasibility of left bundle branch area pacing (LBBAP) compared to right ventricular outflow tract septal pacing (RVOSP). We conducted a prospective, single-center, observational study involving 200 consecutive patients who required pacemaker implantation. The patients were divided into two groups (LBBAP and RVOSP), with 100 patients in each group.

Background: While clinical indicators for synchronized cardioversion in regular supraventricular tachycardias are well-established, their application by prehospital emergency medical services (EMS) still needs to be explored.

Objective: The purpose of this study was to evaluate the factors influencing the decision-making process of prehospital EMS personnel to perform synchronized cardioversion in adults with narrow QRS regular tachyarrhythmias.

Methods: This descriptive study included 598 paramedics actively engaged in prehospital EMS.
