Recurrence and non-improvement of European Heart Rhythm Association symptom scores after atrial fibrillation ablation: the role of left atrial fractal dimension.

ABSTRACT:

Background

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia. Atrial remodeling often leads to impaired clinical outcomes after AF ablation. Understanding the factors influencing AF recurrence after ablation is crucial for improving patient prognosis. This study aimed to investigate the relationship between left atrial (LA) morphologic heterogeneity, quantified by fractal dimension (FD), and AF recurrence, as well as the impact on European Heart Rhythm Association (EHRA) symptom scores following ablation.

Methods

This study retrospectively collected the data of patients with AF who underwent their first radiofrequency ablation procedure at Lanzhou University Second Hospital between October 2019 and September 2022 and underwent cardiac computed tomograp
