Does cryoballoon ablation prevent inappropriate ICD shocks in a pediatric patient with Brugada syndrome and paroxysmal atrial fibrillation?
Cryoballoon ablation can be successfully performed for pulmonary vein isolation in a pediatric patient with Brugada syndrome to treat paroxysmal atrial fibrillation and prevent inappropriate ICD shocks.
Supports cryoballoon PVI feasibility in pediatric Brugada with AF; leaves open efficacy for preventing inappropriate ICD shocks.
We report the case of a 14-year-old girl with Brugada syndrome (BS) (Figure) admitted to our institution because of repeated inappropriate implantable cardioverter-defibrillator (ICD) shocks elicited by episodes of paroxysmal rapid atrial fibrillation (AF). Three years earlier she received a single-chamber ICD implantation because of aborted sudden cardiac death due to ventricular fibrillation and 2 years after she developed paroxysmal AF. Pharmacological therapy with sotalol and bisoprolol failed to maintain sinus rhythm and to avoid inappropriate ICD interventions. Due to the inefficacy of sotalol and the inability to use a class Ic drug for the prophylaxis of paroxysmal AF, we performed a successful pulmonary vein isolation (PVI) by means of cryoballoon (CB) ablation. Although CB ablation of paroxysmal AF has been proven as an effective alternative to radiofrequency in achieving PVI in adults, no data have been reported about CB ablation for AF in children. To our knowledge, this is the first report of successful CB isolation of PVs in a child with BS.

Conte et al. (2013) conducted a case report in Brugada syndrome and paroxysmal atrial fibrillation (n=1). Cryoballoon ablation for pulmonary vein isolation was evaluated on Successful pulmonary vein isolation. Cryoballoon ablation successfully achieved pulmonary vein isolation in a 14-year-old girl with Brugada syndrome and paroxysmal atrial fibrillation.
