| Number of valid PF/RF applications for PVI, median (Q1/Q3)b | 66.0 (58.0/81.0) |
| RF; n = 136 | 31.0 (24.0/37.0) |
| PF; n = 137 | 37.0 (28.0/50.0) |
| Fluid delivered via the study catheter(s), median (Q1/Q3), mL; n = 127c | 400.0 (300.0/500.0) |
CTI, cavotricuspid isthmus; DE STSF, dual-energy THERMOCOOL SMARTTOUCH SF; LA, left atrial; PF, pulsed field; PV, pulmonary vein; PVI, pulmonary vein isolation; RF, radiofrequency.
aCTI ablation was included.
bThe PF ablations with all applications <100% status were excluded and considered as invalid; the time spent on energy delivery was counted as ablation time, excluding the intervals between each delivery.
cFor 10 patients, fluid was delivered via the study catheter, but the amount was not registered by the site.
