Characteristics of the patients
A total of 304 consecutive patients who underwent successful LAAC with
the Watchman occluder between February 2012 and April 2017 at the
Lichtenfels site were treated with the ACT regimen. A total of 220
patients at the Coburg site underwent Watchman implantation between
November 2016 and May 2018 and received DAPT regimen. The baseline
characteristics of the two groups are shown in Table 1. The patients in
the DAPT group were significantly older, less likely to have a history
of liver dysfunction at baseline, and had lower left ventricular
ejection fraction, more tendency to take drugs with a predisposition to
bleeding and have a history of MB events. The mean
CHA2DS2-VASc and HAS-BLED scores were
4.8±1.5 and 3.3±0.7 for the DAPT group, respectively, and 4.5±1.7 and
3.4±1.0 for the ACT group, respectively.
