BACKGROUND: Lone atrial fibrillation (LAF) develops in younger individuals without cardiovascular or pulmonary disease. As pulmonary vein isolation has been recognized as an optimal treatment for drug-resistant atrial fibrillation, cryoballoon ablation with second-generation balloon (CB-A) may be an ideal solution for LAF patients. OBJECTIVE: The aim of this study was to investigate acute success, periprocedural complications and outcome over a 12-month follow-up period in a cohort of patients having undergone PV isolation (PVI) for LAF using CB-A technology. METHODS: 75 consecutive patients (50 male, mean age 47±12 years) with a diagnosis of lone paroxysmal atrial fibrillation who underwent Pulmonary Vein Isolation (PVI) by CB-A from June 2012 were included. All patients underwent this procedure with the 28 mm CB-A. A total of 299 PVs (100%) could be isolated with CB-A alone. RESULTS: The freedom from AF recurrence after a single procedure was 92% of patients during the entire 13-month follow-up. When considering a blanking period (BP) of 3 months, success rate was 93,3%. Transient phrenic nerve palsy (PNP) was the most frequent complication occurring in 5.3% of individuals (4 patients); complete recovery was documented for all of these patients prior to hospital discharge. CONCLUSIONS: CB-A is extremely effective in achieving PVI and affords freedom from AF at 13-month follow-up in 93% of young patients affected by drug-resistant LPAF following a 3-month BP. The most frequent complication observed was PNP, which reverted prior to discharge in all patients. This article is protected by copyright. All rights reserved. |
