Key result
Autopsy of a 68-year-old woman 7 months after cryoballoon ablation for paroxysmal atrial fibrillation revealed no macroscopic or microscopic thrombus formation around the pulmonary veins.
Why the study?
Does cryoballoon ablation for paroxysmal atrial fibrillation result in late phase thrombus formation around pulmonary veins?

Does cryoballoon ablation for paroxysmal atrial fibrillation result in late phase thrombus formation around pulmonary veins?
Postmortem histopathology 7 months after cryoballoon ablation for paroxysmal atrial fibrillation showed no thrombus formation, supporting experimental evidence of lower thrombotic risk.
Answers are grounded in this paper and cite their sources.
No late thrombus in this autopsy case; leaves open cryoballoon thrombogenicity assessment in larger studies.
We report the autopsy case of 68-year-old woman who received cryoballoon (CB) ablation for paroxysmal atrial fibrillation 7 months before death. Both macroscopic and microscopic findings revealed no thrombus formation around pulmonary veins. Previous experimental studies have shown the lower risk of thrombus formation in CB ablation as compared to radiofrequency ablation. Our findings in the human autopsy case may support this merit of CB ablation. To confirm this benefit of CB ablation, further studies regarding histopathology of CB ablation should be performed.

Ukita et al. (2019) conducted a case report in paroxysmal atrial fibrillation (n=1). cryoballoon ablation was evaluated on thrombus formation around pulmonary veins. Autopsy of a 68-year-old woman 7 months after cryoballoon ablation for paroxysmal atrial fibrillation revealed no macroscopic or microscopic thrombus formation around the pulmonary veins.
