All 100 patients underwent cryoballoon ablation (CB) (Artic Front Advance™, Medtronic, Minneapolis, MN). Standard procedures were used, including use of intracardiac echocardiography (AcuNav, Biosense Webster), fluoroscopy, and electroanatomic mapping (NavX, Abbott, and CARTO, Biosense Webster). Briefly, for CB, a minimum of two cryoablations were delivered per pulmonary vein (PV) with ablation lasting 3–4 minutes to a nadir temperature < 55°C. If PV isolation (PVI) was not achieved with CB, then focal ablation was performed using either Cryocatheter (Cryocath, Medtronic) or radiofrequency catheter to achieve PVI. Entry block was confirmed by pacing from the distal poles of the coronary sinus catheter for the left sided PVs and elimination of right sided PVs. Exit block in all PVs was evaluated by pacing around the circular mapping catheter placed sequentially in each PV.
Artic front advance
Manufactured by Medtronic
Sourced in United States
The Artic Front Advance is a cryoablation catheter designed for the treatment of atrial fibrillation. It is used to create controlled freezing of targeted cardiac tissue to interrupt electrical signals and restore normal heart rhythm. The device features a flexible catheter tip that can be maneuvered to reach specific areas of the heart.

Pre-procedure transesophageal echocardiography was performed to assess the left atrium, left atrium appendage, and pulmonary vein anatomy. Cryoballoon ablation was performed using a 28-mm cryoballoon (Artic Front Advance; Medtronic) using standard protocols to achieve persistent bidirectional conduction block in all pulmonary veins. During the procedure, esophageal temperature was monitored (CIRCA S-Cath, Circa Scientific Inc.). After circumferential antral vein isolation, a 30-min waiting period was conducted to assess spontaneous conduction recovery. Pericardial effusion was ruled out after PVI by echocardiography.

The study cohort consisted of consecutive patients presenting with AT post AF ablation with the cryoballoon (Artic Front Advance, Medtronic, MN, USA) who underwent a radiofrequency catheter ablation guided by the novel noncontact CD mapping technology at the Heart Rhythm Management Center, UZ Brussels, Belgium, between December 2019 and April 2020. The study was retrospective in nature and approved by the local ethics committee of our Institution.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
