Aim:To analyze the factors for recurrence of right atrioventricular accessory pathway after radiofrequency catheter ablation (RFCA) in order to elevate the profitable effects on RFCA.METHODS: We retrospectively analyzed the clinic features of patients who were cured by RFCA with atrioventricular accessory pathway. RESULTS:During 3 to 24 months′follow-up ,recurrences were found in 10 cases. The recurrent rate of right atrioventricular accessory pathway among 68 patients was 14.71% . CONCLUSION: The high recurrence in the patients with right atriovent- ricular accessory pathway after RFCA is related to the anatomical position, difficult to get to the target sites, catheter stability and immediate success time. |
