Conclusion
Temperature controlled high power short duration ablation with 90watts for 4 seconds for PVI using the QDot catheter lead to a short procedure and RF time with no major complications in this trial. Despite optimized temperature control and power adjustment, steam pops not leading to clinical implications like tamponade or neurological deficits occurred in 39% of patients. The different amount of steam pops compared to initial trials maybe due to the used ablation generator.
