The Extended Utility of CHA2DS2VASc and HAS-BLED Scores in the Selection for Transcutaneous Left Atrial Appendage Closure.

HAS-BLED, but not CHA2DS2CVASc score, may be a useful tool to predict the prognosis of patients after LAAC. Qualification for LAAC based on the risk of stroke should not differ from qualification for anticoagulation. Despite the worse prognosis of patients with the highest bleeding risk, this group is likely to experience the greatest benefit from reducing the bleeding risk from LAAC.
