Key result
Cryoballoon ablation for atrial fibrillation was associated with recurrent and late-onset coronary spasms, potentially due to autonomic nervous imbalance from affected ganglionated plexi.

Does cryoballoon ablation cause recurrent and late-onset coronary spasms in patients with paroxysmal atrial fibrillation?
Cryoballoon ablation for atrial fibrillation may cause recurrent and late-onset coronary spasms, potentially due to autonomic nervous imbalance from affected ganglionated plexi.
May warrant vigilance for late coronary spasms after cryoballoon ablation; leaves open ganglionated plexi disruption as causal mechanism.
The feasibility of cryoballoon ablation for treating paroxysmal atrial fibrillation (AF) has been reported. On the other hand, several complications specific to ablation using a cryoballoon may be expected. The prior reports of coronary spasms during procedures describe some mechanisms of coronary spasms; however, those mechanisms remain unknown. We describe a case of recurrent and late-onset coronary spasms after cryoablation procedure that may suggest a possible mechanism not only via the cooling effect on the coronary artery but also via autonomic nervous imbalance by the affected ganglionated plexi located close to the pulmonary veins.

Watanabe et al. (2016) conducted a case report in Paroxysmal atrial fibrillation (n=1). Cryoballoon ablation was evaluated on Recurrent and late-onset coronary spasms. Cryoballoon ablation for atrial fibrillation was associated with recurrent and late-onset coronary spasms, potentially due to autonomic nervous imbalance from affected ganglionated plexi.
