3.1 Characteristics of patients, per study group
Characteristics of patients are shown per study group in Table 1.
Overall, LAPWI was achieved in 54 of the 55 patients (98%). LAPWI was
not achieved in 1 patient (2%) despite numerous high-power RF energy
applications. For 50 patients in whom LAPWI was achieved, RF energy was
applied only to the LA roof and floor, but 5 patients required
additional RF application at the center of the LAPW or
interior surface of the LA. With
the exception of body weight, patient characteristics, echocardiographic
variables, and serologic test results did not differ significantly
between the Successful first-pass group and the Gap group. Body weight
was greater in the Gap group.
