Abstract

BACKGROUND: The OPTION trial demonstrated that, after atrial fibrillation ablation, left atrial appendage closure (LAAC) reduced nonprocedural bleeding and was noninferior to oral anticoagulation (OAC) with respect to death, stroke, or systemic embolism.

OBJECTIVE: This study aimed to evaluate event rates in relation to patients' baseline stroke risk.

METHODS: The primary safety endpoint was nonprocedural major or clinically relevant nonmajor bleeding, and the primary efficacy endpoint was a composite of death, stroke, or systemic embolism, measured at 3 years. Patients were stratified based on a CHA

RESULTS: The trial enrolled 1600 patients aged 70 ± 8 years, with 738 and 862 patients having CHA

CONCLUSION: After ablation of atrial fibrillation, the rates of cardiovascular events are low among individuals with a CHA
