Long-term outcome of invasive electrophysiological studies and catheter ablation in patients with patent foramen ovale and atrial septal defect-A single-center retrospective cohort study.

ABSTRACT:

Introduction

Patients with atrial septal defect (ASD) and patent foramen ovale (PFO) are prone to atrial arrhythmias due to structural and surgical alterations. While radiofrequency catheter ablation (RFCA) is a common treatment, arrhythmia recurrence remains a clinical challenge. This study aimed to assess arrhythmia patterns, procedural outcomes, and long-term recurrence following electrophysiological interventions.

Methods

A retrospective cohort study was performed at a tertiary center including patients with ASD or PFO undergoing invasive electrophysiological procedures. Clinical and procedural data were extracted from medical records. Arrhythmias were classified based on electrocardiographic and electrophysiological findings. Kaplan-Meier analysis was used to assess eve
