OP-127 Clinical Impact of the Bonus Freeze in Pulmonary Vein Isolation in Paroxysmal Atrial Fibrillation Using the Second Generation Cryoballoon




Background


Bonus application during pulmonary vein isolation using the novel second generation Cryoballoon is commonly performed. In this study, we aimed to investigate the clinical impact of the bonus freeze on the longterm electrical isolation of the pulmonary veins in patients with paroxysmal atrial fibrillation (PAF).




Methods


A total of 134 patients with PAF were ablated using the second generation Cryoballon. In group I, patients with one bonus freeze after successfull pulmonary vein isolation 93 pts (female: 34; age: 62 years) were included, while in group II, patients without bonus freeze after the first successfull application 41 patients (female; 63years) were investigated. Follow up of the study group were performed at 3rd and 6th months after the procedure in the outpatients clinic using a 7-day Holter-ECG recording. In addition, a telephone interview was made with all patients. The primary endpoint was the absence of atrial fibrillation and atrial tachycardia.
