Use of Intracardiac Echocardiography or Left Atrial Appendage Radiography to Guide Implantation of a Left Atrial Appendage Occlusion Device

Use of Intracardiac Echocardiography or Left Atrial Appendage Radiography to Guide Implantation of a Left Atrial Appendage Occlusion Device.

A total of 40 patients with atrial fibrillation were scheduled to receive left atrial appendage occlusion, which were divided into two groups. The operation was performed under the guidance of intracardiac echocardiography and left atrial appendage radiography, respectively (allocation ratio 1:1). During the operation, the total amount of contrast medium injected, the fluoroscopy time and the time from femoral vein puncture to transseptal puncture to closure were recorded in all patients. The diameter and depth of the left atrial appendage opening were measured by angiography in group A(ICE group), and measured by ICE in group B(radiography group). The size of the occluder device was selected according to the measurement size of the two groups, the occluder device success rate of the two groups was compared, and the relationship between measurement size and the size of the occluder device was obtained.
