Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The investigators will analyze the pathologic findings of atrial tissue after cryoablation using two probes and early and long-term outcomes with Holter monitoring. Atrial fibrillation burden 3 months and 1 year postoperatively and atrial activity will be checked.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
However, sometimes, it was inconvenient due to excess flexibility, wide lesion related to excess low temperature and time-consuming detachment from atrium after cryoablation. The investigators introduced Atricure cryoprobe (Nitreos Oxide based) in hope of overcoming these shortcomings of ATS probes last year.
Up to date, the investigators have been satisfactory in terms of the surgical convenience. On the other hand, we have the questionability of transmural lesion of Atricure probe because of the higher temperature of Atricure probe compared with ATS probe.
The aim of this study is compare the surgical convenience and early and long-term outcomes of cryomaze procedure using nitrous oxide with using Argon gas.
