Pulmonary vein isolation (PVI) has become a cornerstone therapy in the treatment of atrial fibrillation (AF). Patients with overweight or obesity suffer more often from AF, and studies investigating the safety and feasibility of PVI in these patients have shown varying results. In this study we analyzed PVI performed with the 2nd generation cryoballoon (CB) with regard to safety, procedure and fluoroscopy time in patients with normal weight, overweight and obesity. We analyzed 228 consecutive patients treated with CB PVI in our hospital in 2018 and 2019. Fifty nine (25.88%) patients presented with normal weight (body mass index (BMI) of 30). All pulmonary veins (PV) were isolated successfully. Concerning procedural parameters, neither complications, procedural time, nor fluoroscopy time differed significantly. There was a significant increase of dose area product (DAP) in obese patients compared to normal weight and overweight patients (2035.5 ± 1930.1 μGym2 vs. 975.3 ± 814.9 vs. 1325.1 ± 2081.3, p = 0.001) but no significant difference between overweight and normal weight patients (p = 0.611). Our follow-up data of 168 patients (73.68%) observed for 12 months showed no differences in the recurrence of AF in the three BMI groups [80.9% vs. 83.3% (p = 0.733) vs. 86.55% (p = 0.460)]. In conclusion, CB PVI in overweight and obese patients is safe with similar levels of complications and recurrence of AF as patients of normal weight. However, obese patients and operators are exposed to higher radiation doses. |
