Abstract
Objectives: This study aims to compare the success of two different energy sources, radiofrequency versus cryoablation, in patients with atrial fibrillation.Patients and methods: Between August 2012 and August 2017, a total of 55 patients (27 males, 28 females; mean age 51.6±11.2 years;range, 44 to 71 years) with atrial fibrillation who underwent isolated left atrial ablation during mitral valve surgery in our clinic were included. Radiofrequency was applied to 41 patients and cryoablation to 14 patients. In both procedure, ablation was performed to isolate all pulmonary veins. Radiofrequency ablation utilized a RF current that was applied in a point-by-point mode, heating the tissue and leading to cellular necrosis. Cryogenic ablation induced necrosis by pumping refrigerant (nitrous oxide) through a balloon in a single-step mode, thereby freezing the tissue. The success of both techniques was evaluated through control echocardiograp...
