Cryoballoon or Radiofrequency Ablation for Repeat Procedures?
The study included 474 consecutive patients undergoing repeat ablation from the 1STOP Italian Project who received treatment with a different technique from the index procedure. There were 249 patients in the RF-the-CB group and 125 in the CB-then-RF group. There were more women in the RF-then-CB group versus the CB-then-RF group (21% vs. 30%), as well as more persistent AFib (33% vs. 22%), a longer duration of AFib (60 months vs. 31 months), and more hypertension (50% vs. 36%). According to the study results, the number of reconnected pulmonary veins was 3.7±0.7 in the RF-then-CB group compared with 1.4+1.3 in the CB-then-RF group (P<0.001). The authors reported significantly less AFib recurrence in the CB-then-Rf group (22% vs. 8%; HR=0.46; 95% CI, 0.24 to 0.92; P=0.025).The only identified independent predictor of AFib recurrence, according to the researchers, was cohort designation.
