“…In spite of comparable acute procedural success rates between RF and Cryo, a concern regarding Cryo is the procedure's significantly high recurrence rates during long‐term follow‐up . In these studies, the higher recurrence rate of Cryo can possibly be explained by the smaller‐tip (4‐mm) Cryo catheter.…”

“…Friedman et al reported that acute procedural success was achieved in 83% of patients with supraventricular tachycardia (91% for AVNRT, 69% for AVRT, and 67% for AV junction in patients with atrial fibrillation) and long‐term success after 6 months was 91% overall in patients with acute procedural process. The success rate of cryoablation itself in this study was lower than that in the previous studies . There were several factors that might have influenced the results.…”

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.

“…11 Cryoablation, on the other hand, is an effective and safe alternative to RFCA, with no permanent AV block reported in the larger studies, and a comparably excellent acute success rate. 9,10,21 However, the long-term recurrences are consistently higher than for RFCA among the published studies. Currently available data from the larger studies on the acute and long-term outcomes of catheter ablation of AVNRT are summarized in Table 1.…”

Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common, highly symptomatic paroxysmal supraventricular tachycardia. Despite pharmacological treatment and vagal maneuvers for acute termination, catheter ablation has emerged as the first line treatment for the cure of AVNRT episodes. Several studies during recent years have investigated the efficacy, safety and long-term effect of both radiofrequency ablation and cryoablation of the slow pathway for the treatment of AVNRT. Innovations such as mapping systems and dedicated catheters have contributed by extending the indication to AVNRT ablation, even in particular subset populations such as children and congenital heart disease patients. We performed this review with the aim aim of summarizing and discussing current perspectives on the treatment of AVNRT, mainly focusing on catheter ablation energy sources and long-term results.
