About this study
Official title: Combination of Cone Beam Computed Tomography and Cardiac Computed Tomography Angiography: Left Atrial Appendage Occlusion Under Three-dimensional Computed Tomography Fusion Image Guidance
Left atrial appendage occlusion is being widely recommended as a treatment strategy for patients with nonvalvular AF to prevent stroke, especially those who cannot tolerate long-term oral anticoagulation or have other reasons for nonpharmacologic therapy. Currently, there are a number of guidance for left atrial appendage occlusion, such as transesophageal echocardiography, intracardiac echocardiogram, fluoroscopy, computed tomographic/computed tomographic angiography and so on. Procedures such as atrial septal puncture, device size selection and operational view are guided by different methods in various centers. Our center has developed a new approach to guidance: Cone-beam CT and cardiac computed tomographic angiography were combined by three-dimensional - three-dimensional image fusion in guiding left atrial appendage occlusion.
Read the detailed description
Eligible NVAF patients were recruited consecutively and received our LAAO workflow of local anesthesia, intracardiac echocardiography-guided transseptal puncture, and 3DCTA-3DCBCTF fusion-guided occluder implantation. The primary outcome was optimal occluder implantation (successful implantation with no occluder recapture and replacement). Other outcomes were procedure/fluoroscopic time, contrast agent consumption, radiation dose, and peri-procedure complications. We compared our results with existing publications of LAAO guided by 3DCTA and two-dimensional fluoroscopy (3DCTA-2DF) fusion images.
