About this study

This study is a prospective, multi-center, randomized controlled trial. The subjects are patients scheduled to undergo a combined procedure of atrial fibrillation (AF) ablation and left atrial appendage (LAA) occlusion. After signing the informed consent form, the subjects will be randomly assigned to either the cardiac Computed Tomography (CT) group or the Digital Subtraction Angiography (DSA) group. The operator will select the appropriate LAA occluder size for implantation based on different measurement methods. All subjects will undergo clinical follow-up before discharge and at 3 months postoperatively, as well as telephone follow-up 1-5 years after the surgery.
