Consistency of LGE-MRI Fibrosis and EAM Low-voltage Area
Recruiting now
Conditions studied: Atrial Fibrillation
In brief
This study aims to: 1. Assess the consistency of LGE-MRI bi-atrial fibrosis and electroanatomical mapping of bi-atrial low voltage region 2. To evaluate the electroanatomical characteristics of different types of fibrosis (dense fibrosis, patchy fibrosis, etc.) in different locations of the left and right atrium; 3. To explore the correlation between preoperative and postoperative bi-atrial fibrosis and long-term recurrence in patients with atrial fibrillation.
