Intra-operative factors
The specific intra-operative factors are summarized in table 2. 194
patients (81.1%) were performed in an elective setting, with no
difference between the groups (p=0.48). Unsurprisingly, the majority of
patients in the cohort had MVS (186 patients, 77.8%) with no
significant difference between the groups (p=0.17). There were 105
patients (43.9%) who had concomitant CABG with a lower number in the
Cox-Maze group (27.1%, p=0.003). The CPB times in the Cox-Maze group
was 165.7+/-64.9 minutes which was comparable to the No Surgical AF
treatment group (p=0.77). Similarly, the X-clamp times for the Cox-Maze
group (135.1+/-40.6 minutes) was not any higher (p=0.91). 9 patients
required IABP at the end of the case (3.8%) with no difference between
the groups (p=0.67).
