Abstract：Objective To report single-center experience on CBA combined with LAAC in treat-ment of AF.Methods A retrospective study was conducted on 27 AF patients undergoing one-stop surgery of CBA combined with LAAC in Department of Cardiovascular Diseases of the People's Hospital of Liaoning Provincie from August 2020 to November 2022.The efficacy and safety of the surgery were analyzed.Results There were 22 patients(81.5％)with LAmbre and 5 patients with Watchman(18.5％,including one case of 24 mm Watchman FLX).All the patients achieved complete pulmonary vein isolation,and conversion to sinus rhythm during operation.During a mean follow-up of 30.0±9.2 months,24 patients(88.9％)maintained sinus rhythm at 12-month follow-up,and 22 patients(81.5％)maintained sinus rhythm at 24-month follow-up.TEE at 3 months after operation displayed that all the devices were in good positions and no PDL or DRT was observed.In the 11 patients undergoing cardiac enhanced CT in 12-36 months after surgery,PDL was detected in one patient(9.1％),and uncomplete endothelialisation of the device was observed in another one(9.1％)using the Watchman device.TEE at 26 months revealed one patient(3.7％)of DRT.Conclusion One-stop surgery of CBA combined with LAAC is a feasible treatment option for patients with NVAF and at high risk of stroke.
