## TL;DR

This review explores how genetic differences may influence the recurrence of atrial fibrillation after ablation treatment.

## Contribution

The paper systematically reviews genetic polymorphisms linked to atrial fibrillation recurrence post-ablation.

## Key findings

- Over 100 genetic loci associated with atrial fibrillation have been identified via GWAS.
- Genetic polymorphisms may play a role in AF recurrence after catheter ablation.
- Understanding these genetic factors could help develop personalized treatment strategies.

## Abstract

Atrial fibrillation (AF) is one of the most common cardiac arrhythmias, but its
pathogenesis is still poorly understood. Catheter ablation is one of the most
effective treatments for AF, but recurrence after ablation remains a challenge.
There has been much research into the association of AF recurrence with several
factors, including genetics. Over the past decade or so, significant advances
have been made in the genetic architecture of atrial fibrillation. Genome-wide
association studies (GWAS) have identified over 100 loci for genetic variants
associated with atrial fibrillation. However, there is relatively little
information on the systematic assessment of the genes related to AF recurrence
after ablation. In this review article, we highlight the value of genetic
polymorphisms in atrial fibrillation recurrence after catheter ablation and their
potential mechanisms in the recurrence process to enhance our understanding of
atrial fibrillation recurrence and contribute to individualized treatment
strategies for patients with AF.
