Conclusion
CCTA is feasible to evaluate PDL and device endothelialization after
LAAC. The maximum diameter of LAA orifice can independently predict the
occurrence of postoperative PDL of LAAC. Future studies are warranted to
validate the value of maximum diameter of LAA orifice as a screening
index for judgment of PDL risk in patients before LAAC, and as a
reference basis for the decision making of individualized anticoagulant
therapy after LAAC and AFCA.
