Evaluation of a new epicardial cryoablation system for the treatment of Cardiac Tachyarrhythmias

Background: With the recent reports of success, there is now increasing use of cryoablation as a standalone, minimally invasive procedure to treat various cardiac arrhythmias. With increased use, a need for new devices and treatment strategies to deliver improved outcomes has emerged. In this study we investigated the performance of a new super critical nitrogen (SCN) epicardial cryoprobe for the targeted ablation of cardiac tissue. We hypothesized that the SCN technology would enable the rapid, effective delivery of ultra-cold temperatures thereby enabling more effective ablation.
