Abstract

Myocardial bridge is a congenital anomaly characterized by narrowing of some of the epicardial coronary arterial segments running in the myocardium during systole. Occasionally, the compression of a coronary artery by a myocardial bridge can be associated with the clinical manifestations of myocardial ischemia, and might even trigger a myocardial infarction or malignant ventricular arrhythmias. We report a case of ventricular fibrillation due to coronary spasm at the site of myocardial bridge. A 56-year-old man who had suffered from bronchial asthma was given remifentanil combined with sevoflurane in general anesthesia for endoscopic sinus surgery. During the surgery, ventricular fibrillation occurred following coronary spasm with bradycardia, hypotension, bronchospasm. we found myocardial bridge that coincided with an area of coronary spasm after coronary angiography.
