![]() ![]() ![]() The incidences of SCEs in the RMN group and the MC group were 5.77 and 32.26%, respectively (X 2 = 20.63 P < 0.05). There were 26 total cases of SCEs in this study, including 6 cases in the RMN group and 20 cases in the MC group. The incidence and potential risk factors of SCEs were compared between the two groups. All patients underwent cerebral magnetic resonance imaging within 48 h before and after the ablation procedure to assess cerebral embolism. Patients were divided into RMN group ( n = 104) and manual control (MC) group ( n = 62), and analyzed for their demographic, medical, echocardiographic, and risk predictors of SCEs. Methods and Results: We performed a prospective study of 166 patients with paroxysmal or persistent AF who underwent pulmonary vein isolation. The purpose of this prospective study was to investigate the incidence, risk predictors and probable mechanisms of SCEs in patients with AF ablation and the potential impact of RMN on SCE rates. 5Department of Cardiology, Fuwai Hospital, Chinese Academy of Medical Sciences - Peking Union Medical College, Beijing, Chinaīackground: The incidence of silent cerebral embolisms (SCEs) has been documented after pulmonary vein isolation using different ablation technologies however, it is unreported in patients undergoing with atrial fibrillation (AF) ablation using Robotic Magnetic Navigation (RMN).4Department of Cardiology, The First Hospital Affiliated to Soochow University, Suzhou, China.3Department of Radiology, Wuxi People's Hospital Affiliated to Nanjing Medical University, Wuxi, China.2Department of Cardiology, Xuzhou Central Hospital, Xuzhou, China.1Department of Cardiology, Wuxi People's Hospital Affiliated to Nanjing Medical University, Wuxi, China.Jie Zheng 1 †, Meng Wang 2 †, Qun-feng Tang 3 †, Feng Xue 4 †, Ku-lin Li 1, Shi-peng Dang 1, Xiao-yu Liu 1, Xiao-xi Zhao 1, Chang-ying Zhang 1, Zhi-ming Yu 1, Bing Han 2 *, Ting-bo Jiang 4 *, Yan Yao 5 * and Ru-Xing Wang 1 * ![]()
