Discussion

Preoperative CMR analysis reveals differences in left atrial function and fibrosis between AF types, suggesting personalized treatment strategies.

Patients with persistent AF show increased left atrial volumes and reduced function compared to those with paroxysmal AF.
Utilizing 3D-LGE CMR, persistent AF patients exhibit more significant myocardial enhancement and scar tissue.
Assessment of left atrial fibrosis through myocardial strain imaging can provide insights into function and remodeling.
This research highlights potential applications for improving management and monitoring of atrial fibrillation patients.

Chong et al. (2025) studied this question.
