Coronary artery spasms and/or coronary air embolisms and contrast-induced encephalopathy during cryoablation of atrial fibrillation: a case report.

ABSTRACT:

Background

ST-segment elevations in electrocardiogram associated with coronary air embolisms (CAEs) and/or myocardial ischaemia induced by coronary artery spasms (CASs) are rare complications during ablation of atrial fibrillation (AF); some patients develop severe conditions. Contrast-induced encephalopathy (CIE) is also a rare but severe complication associated with the use of iodinated contrast agents during various cardiovascular and neurovascular procedures. Its occurrence during ablation, particularly AF ablation, remains unreported.

Case summary

We report a case in which CASs and/or CAEs associated with ST-segment elevation were observed, accompanied by worsening haemodynamics during AF cryoablation. Insertion of an intra-aortic balloon pump improved the haemodynamics
