Abstract:
Objective: To investigate the value of real-time three-dimensional transesophageal echocardiography (RT-3D-TEE) in percutaneous left atrial appendage (LAA) transcatheter occlusion (PLAATO) in patients with non-valvular atrial fibrillation. Methods: Totally 62 patients with non-valvular atrial fibrillation who underwent PLAATO were examined with two-dimensional transesophageal echocardiography (2D-TEE), RT-3D-TEE and cardioangiography (CAG). The maximum diameter, minimum diameter and depth of LAA were measured and compared respectively. According to the maximum diameter of LAA measured with RT-3D-TEE, occluder with appropriate type was selected, and LAA occlusion was performed under the guidance of RT-3D-TEE and CAG. Follow-up was conducted after operation. Results: Occlusion was successfully performed in all 62 patients, the success rate was 100%, and the compression rate was (19.78±6.92)%. No serious complications occurred during the operation and follow-up period. There was significant difference of the maximum diameter of LAA measured with 2D-TEE, RT-3D-TEE and CAG (P=0.029). The maximum diameter of LAA measured with RT-3D-TEE was higher than that measured with 2D-TEE, while lower than that measured with CAG. There was no significant difference of the minimum diameter nor depth of LAA measured with 2D-TEE, RT-3D-TEE and CAG (both P>0.05). The maximum diameter of LAA measured with CAG (r=0.925), RT-3D-TEE (r=0.841) and 2D-TEE (r=0.716) were positively correlated with the size of occluder (all P≤0.001). Conclusion: RT-3D-TEE can be used for preoperative screening, intraoperative guidance and post-operative follow-up of PLAATO for non-valvular atrial fibrillation, which may accurately describe the shape of LAA and evaluate the effect of occlusion.
