Optimizing Ablation Duration using Dormant Conduction 139 6 6.5 Conclusions An additional ablation with 90, 120 or 150s after time-to-isolation in cryoballoon ablation caused a stepwise decrease in reconnection/DC, a decrease in additional ablations for the treatment of reconnection/DC, while recurrences and complication rates at one year were not significantly different. In addition, the rate of repeated procedures during follow-up decreased with increasing additional ablation. Therefore, based on our data selecting an additional ablation of 150s is the most appropriate approach in time-to-isolation based ablation.
