Cryoballoon ablation to the left superior pulmonary vein can rarely be complicated by severe, prolonged sinus arrest.
Highlights a rare but severe procedural complication during cryoballoon ablation; leaves open the.
A 63-year-old man was referred to our hospital for his palpitation due to atrial fibrillation. He was admitted for catheter ablation. Cryoablation was applied to the left superior pulmonary vein for 180 seconds, and its potential disappeared in 22 seconds. The lowest temperature was -45°C. Suddenly, sinus arrest was observed 1 minute after the completion of freezing. The right ventricle was paced but no atrial potential was observed for 5 minutes until normal sinus rhythm resumed. We report a case of severe sinus arrest after cryoablation to the left pulmonary vein.

Miki et al. (2019) conducted a case report in Atrial fibrillation (n=1). Cryoablation to the left superior pulmonary vein was evaluated on Sinus arrest. Cryoablation to the left superior pulmonary vein resulted in a severe, prolonged sinus arrest lasting 5 minutes in a 63-year-old man with atrial fibrillation.
