Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Very high power-short duration ablation
PVI performed by point-by-point very high power-short duration radiofrequency ablation (QDOT-micro catheter, Biosense Webster; Qmode+; 90 W; 4 sec; target intertag distances: posterior wall 4 mm, proximity of the esophagus 5 mm, all other 3 mm)
No interventions assigned to this group
Matched control group conventional ablation
PVI performed by conventional point-by-point radiofrequency ablation (40 W; ablation index-guided: posterior wall 350, other 450; target intertag distance 3.0 - 5.0 mm)
No interventions assigned to this group
