Key result
Cryoballoon ablation for atrial fibrillation can be complicated by life-threatening left main coronary artery spasm with significant hemodynamic compromise.
Why the study?
Coronary artery spasm is a life-threatening complication of cryoablation, but there is very little literature describing it.
Case Report (n=1)
Left main coronary artery spasm is a rare but life-threatening complication of cryoballoon ablation for atrial fibrillation that requires prompt recognition and intervention.
Requires vigilance for left main spasm during cryoballoon ablation; leaves open true incidence and prevention strategies.
Well known adverse effects of cryoablation are phrenic nerve and esophageal injury. (1, 2) However, there is very little literature about coronary artery spasm (CAS), a life-threatening complication of cryoablation. We report a case of a 68-year-old Caucasian female, who developed left main coronary spasm (CAS) with significant hemodynamic compromise during cryoablation. Although rare, this complication can be life threatening. Prompt recognition and appropriate intervention is critical for good patient outcome.

Ibrahim et al. (2023) conducted a case report in Atrial Fibrillation (n=1). Cryoballoon ablation was evaluated on Left main coronary spasm (CAS) with significant hemodynamic compromise. Cryoballoon ablation for atrial fibrillation can be complicated by life-threatening left main coronary artery spasm with significant hemodynamic compromise.
