Clinical and Electrophysiological Characteristics of Patients Developing Macroreentrant Atrial Tachyarrhythmias Following Cardiac Surgery: A Retrospective Cohort Study.

ABSTRACT:

Introduction

Macroreentrant atrial tachycardias (MRAT) predominate the atrial arrhythmias in patients with operated heart disease, and advances in interventional electrophysiology and catheter ablation technology have pioneered a shift in their management.

Methods

We retrospectively analyzed clinical, procedural, and outcome data from a cohort of patients who had undergone radiofrequency (RF) ablation for MRAT (utilizing high-density atrial mapping) following cardiac surgery for congenital or acquired heart disease.

Results

Forty-one patients underwent ablation for a MRAT from 2016 to 2023. These patients had a mean age of 50.17 ± 11.71 years and had undergone cardiac surgical intervention a median of 18 years prior to first presentation with atrial tachyarrhythmia. T
