Objectives: Atrial fibrillation (AF), the most common arrhythmia in clinical practice, is a major cause of stroke. Atrial fibrillation increases morbidity and mortality. Nowadays cryoablation therapy is being performed efficiently and safely worldwide. In this paper the clinical outcomes of the patients whom were treated with cryoablation were discussed.
Methods: Between June 2012 and March 2014, patients with paroxysmal AF who were treated with cryoablation were included in the study. The medical records of the patients were retrospectively reviewed. Patients were called to receive information about the symptom recurrence.
Results: Twelve patients were included in the study. Half of the patients were female. The mean age was 48 ± 15 years. Acute procedural success rate of cryoablation was 100%. In one patient transient right phrenic nerve injury occurred which was returned to normal after discontinuation of cryoablation therapy. One patient developed AF episode for 10 minutes in the 4th month of follow-up period.
Conclusion: In patients with paroxysmal atrial fibrillation cryoablation effectively decrease symptoms consistent with the literature.
