Why the study?
Does pulsed field ablation compared to radiofrequency ablation cause coronary artery spasm during mitral isthmus ablation in patients with atrial fibrillation?
Does pulsed field ablation compared to radiofrequency ablation cause coronary artery spasm during mitral isthmus ablation in patients with atrial fibrillation?
Pulsed field ablation of the mitral isthmus is associated with frequent but typically subclinical left circumflex arterial vasospasm compared to radiofrequency ablation.
Answers are grounded in this paper and cite their sources.
PFA mitral isthmus ablation was associated with LCx spasm; leaves open need for monitoring or outcome impact versus RFA.
When creating a mitral isthmus ablation line during catheter ablation of atrial fibrillation, adjacent left circumflex arterial vasospasm frequently occurred with PFA and not RFA but was typically subclinical.
