Safety and efficacy outcomes
The incidence of complications was comparable between the RF and CB cohort (1.3% vs. 2.2%, p=0.67). Pericardial effusion and cardiac tamponade occurred in one patient each in the RF group, and one patient in the CB group developed transient acute kidney injury. There was no significant difference between the success rate of freedom from AF or AT at 1 year follow-up between patients receiving RF vs. CB ablation (59.7% vs. 66.7%, p=0.68) (Figure 1).
