Résumé
Facing an increasing number of radiofrequency ablation (RF) and cryoballoon ablation (CB) procedures for treatment of AF radiation exposure and its reduction is a focus point for interventional electrophysiologists. This study evaluated the procedural parameters of the different ablation methods focusing on radiation exposure and the BMI of the patients. One thousand one hundred and thirty-three first procedural cases of pulmonary vein isolation in patients with paroxysmal and persistent AF treated with RF and CB-based techniques were analyzed retrospectively over a period of 7 years focusing on the endpoints dose area product (DAP, cGycm Of the 1133 patients (mean age 63.4 ± 11.4 years, BMI 28.9 ± 4.7) 335 patients received an RF procedure, 211 patients were treated with the cryoballoon first generation (CB1), and 587 patients with cryoballoon second generation (CB2), respectively. The mean DAP for the PVI was 508 ± 654 cGycm Despite longer fluoroscopy durations in the CB technique, the CB2 resulted in a comparable low radiation exposure in PVI as compared to RF, accompanied by shorter procedure durations.

Background
UNASSIGNED
Facing an increasing number of radiofrequency ablation (RF) and cryoballoon ablation (CB) procedures for treatment of AF radiation exposure and its reduction is a focus point for interventional electrophysiologists.
Objective
UNASSIGNED
This study evaluated the procedural parameters of the different ablation methods focusing on radiation exposure and the BMI of the patients.
Methods
UNASSIGNED
One thousand one hundred and thirty-three first procedural cases of pulmonary vein isolation in patients with paroxysmal and persistent AF treated with RF and CB-based techniques were analyzed retrospectively over a period of 7 years focusing on the endpoints dose area product (DAP, cGycm
Results
UNASSIGNED
Of the 1133 patients (mean age 63.4 ± 11.4 years, BMI 28.9 ± 4.7) 335 patients received an RF procedure, 211 patients were treated with the cryoballoon first generation (CB1), and 587 patients with cryoballoon second generation (CB2), respectively. The mean DAP for the PVI was 508 ± 654 cGycm
Conclusions
UNASSIGNED
Despite longer fluoroscopy durations in the CB technique, the CB2 resulted in a comparable low radiation exposure in PVI as compared to RF, accompanied by shorter procedure durations.
