About this study

Atrial fibrillation (AF) is the most common cardiac arrhythmia in the clinic and can lead to valve regurgitation and a poor prognosis. At present, atrial fibrillation ablation is one of the most effective means for the recurrence of atrial fibrillation in clinical practice, but the recurrence rate is high. Therefore, it is of great significance to find the predictors of relapse after atrial fibrillation ablation for clinical precision treatment. three-dimensional transesophageal ultrasound (3D-TEE) can comprehensively evaluate the valve regurgitation, flap ring changes, atrial or auricular thrombosis in patients with atrial fibrillation. It is also a necessary examination before atrial fibrillation ablation. Therefore, this study intends to combine 3D-TEE and three-dimensional transthoracic echocardiographic (3D-TTE) examination to evaluate the cardiac structure and function of patients. To comprehensively evaluate atrial fibrillation valve regurgitation and explore the predictors of recurrence after atrial fibrillation ablation.
