An interventional study of intracardiac echocardiography in Left Atrial Appendage Occlusion, sponsored by The Second Hospital of Hebei Medical University. Status unknown at 1 site in China. Open to participants aged 18 Years to 100 Years. Per ClinicalTrials.gov, last updated 2023-04-14.

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.
