Head-to-head comparison of non-invasive markers of atrial cardiomyopathy and their association with arrhythmia recurrence after atrial fibrillation ablation

In patients undergoing first-time AF ablation, amplified PWD emerged as the most robust non-invasive marker of AtCM, independently associated with invasively assessed LA-LVS and arrhythmia recurrence. Advanced surface ECG analysis may represent a practical and widely applicable tool for AtCM-associated risk stratification in routine clinical practice.
