Severance Cardiovascular Hospital Yonsei University College of Medicine Summary of Korean Multi-Center Registry Multicenter 96 patients cohort, LAAO with ACP or Watchman: . An acceptable immediate implant success rate of 96.9 % . Acceptable rate (4.1 %) of periprocedural major adverse events During 175.1 patient-year follow-up . 4 ischemic stroke . 1 cardiac death and 4 non-cardiac death . Anticoagulation cessation rate was 93.6 % Severance Cardiovascular Hospital Yonsei University College of Medicine Conclusion LAA occlusion was feasible in patients with high risk of stroke and bleeding with non-valvular AF in Korean population. LAA occlusion might be an option to reduce the thrombus burden in the left atrium because all patients experienced stroke were fully recovered without any sequelae in current study. This benefit may be offset by complications related to the implantation of the device . Severance Cardiovascular Hospital Yonsei University College of Medicine Thanks for Your Attention .
