Abstract

Background: There are few data regarding the outcome of a combined cryo- and radiofrequency (RF)-catheter ablation of various types of supraventricular tachycardias (SVTs) originating from near the normal conduction system. METHODS: We analyzed all patients undergoing combined cryo- and RF- catheter ablation at Mayo Clinic, Rochester, MN as part of the ablation of SVTs with potential risks of injury to the normal conduction system. This study aimed to assess the outcome of a combined cryo- and RF-catheter ablation of various types of SVTs. RESULTS: The study population consisted of 54 patients (38 ± 17 years, 32 men). A combined cryo- and RF-catheter ablation was attempted for septal accessary pathways (APs) in 26, atrioventricular nodal reentrant tachycardia (AVNRT) in 14, atrial tachycardia (AT) in 7, and junctional ectopic tachycardia in 7 patients. Forty-one patients (76%) were successfully ablated with cryoablation, and RF ablation after an unsuccessful cryoablation ablated the SVTs successfully at the same location in 6 patients (11%). Complication occurred in 1 patient (deep vein thrombosis). The cumulative freedom from SVT rate at 30 days after the procedure was 78% and there was no significant difference in the recurrence rate among the SVTs. CONCLUSION: A combined cryo- and RF-catheter ablation is clinically effective in patients undergoing SVT ablation with the potential risk of injury to the normal conduction system.
