Discussion
The major finding of present study are as follows: 33 out of 84 AF
patients, who were underwent Watchman LAAC combined with AFCA, developed
PDL, and incomplete endothelialization was found in 7 out of the 51
patients without PDL by CCTA at 6 months post
procedure. Maximum diameter of LAA
orifice could be used to predict the occurrence of PDL. These data thus
indicate the close association between LAA orifice size and the
occurrence of PDL post LAAC.
