| AimsCryoballoon ablation (CRAB) as a modality for pulmonary vein isolation (PVI) is increasingly being accepted. We aim to study the long-term durability of CRAB in atrial fibrillation.MethodsThe first 51 consecutive patients with documented paroxysmal atrial fibrillation(PAF) who underwent CRAB at our institute were considered. Forty patients formed the study group. Successful PVI was achieved in all the patients. Patients were evaluated with Holter ECG recordings at 1, 3, 6 and 12 months and subsequent follow-up was biannual and based on the clinical status and physician discretion whether symptoms occurred. For the study purpose, a baseline ECG, a 24-h Holter and clinical evaluation were performed in all patients at final follow-up.ResultsA large 28-mm cryoballoon (CB) was used in 38 patients (95%), and the small 23-mm CB in the remaining two individuals (2%). The freedom from atrial fibrillation off-antiarrhythmic drug treatment (AAD) after a single procedure at a mean follow-up of 36.64 months was 57.5% (23/40). Transient right phrenic nerve palsy was the most common complication.ConclusionSingle balloon size CRAB provides a durable atrial fibrillation-free-AAD-free survival in drug-resistant PAF patients over long-term follow-up with a success rate of 57.5% with a single procedure. |
