Procedural characteristics
The LAAC procedure with the LAmbre device was successfully performed in
58 (98.3%) patients in the CM group and in 163 (98.8%) patients in the
MM group. There were no significant differences in LAA size and LAA
anatomy between the two groups. The mean umbrella and cover diameters of
the implanted device were similar in the two groups. The rate of a fully
open umbrella was significantly higher in the MM group than in the CM
group (P<0.001). The rate of a device requiring recapture and
the mean number of recaptures were significantly lower in the MM group
than in the CM group (both P<0.05). LAAC with complete
coverage of the LAA16 was achieved in most of the
patients in both groups (70.2% vs 60.3%). The rates of partial
prolapse and complete prolapse into the LAA neck were also similar in
the two groups (Table 2).
