The perioperative outcomes are summarized in table 3. The overall 30-day mortality was 6.3% (15 patients) with no difference observed between the groups (p=0.05). There was one peri-operative death (1.70%) observed in the Cox-Maze Group compared to 14 patients (8.2%) in the No-surgical AF treatment group. There were 3 cases of stroke in the entire cohort (1.2%) which were observed in the No Surgical AF treatment group (p=0.21). No patients in the Cox-Maze group suffered a peri-operative stroke. There was no difference in return to theatre (p=0.42) between the groups. There were 46 patients (19.2%) who developed respiratory complications with no significant difference between the groups (p=0.06). 32 (13.4%) patients developed AKI requiring temporary filtration/dialysis with no difference between the groups (p=0.16). There were 7 patients (2.9%) with significant GI complications (p=0.50). There were 10 patients (4.2%) who required in hospital-PPM with 3 cases (4.3%) in the Cox-Maze group (p=0.96). The duration of ITU stay (p=0.25) and overall hospital stay (p=0.30) was comparable between the groups.
