    Atrial cardiomyopathy (AtCM) is a significant substrate for atrial fibrillation (AF) and increases the risk of arrhythmia recurrence post-ablation.

  • 2

    Current AtCM diagnosis relies on invasive electroanatomical mapping, limiting its use for preprocedural risk stratification.

  • 3

    This study compares non-invasive markers of AtCM with invasively quantified low-voltage substrate in AF patients undergoing pulmonary vein isolation.

  • 4

    Non-invasive approaches include 12-lead ECG, transthoracic echocardiography, and blood-based biomarkers, but their validation is limited.

  • 5

    The findings aim to enhance the predictive value of non-invasive indicators for arrhythmia recurrence following catheter ablation.
