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.
