Objective
Atrial fibrillation (AF) is one of the leading health problems in the modern era. Cryoablation therapy is an effective and safe method for the management of AF. However, recurrence of AF is still a major problem. In this study, we aimed to investigate the association between pulmonary venous isolation (PVI) time and recurrence of AF.
Methods
Patients undergoing successful cryoablation for AF at Çukurova University Cardiology Department were included in our study. Patients, who showed no obvious pulmonary venous potential in at least one of the pulmonary veins were excluded. Mean PVI time (PVPD time/number of pulmonary veins with potential), total cryoablation time (CAT) and CAT/PVI time ratio were calculated. Patients were followed up for at least 6 months. Recurrence of AF was described as occurrence of clinical AF or detection of at least 30 seconds of AF episode on event recorder. Comparison of two groups was performed by Mann-Whitney-U test.
