Myocardial bridging with a coronary artery aneurysm and left ventricular stunning.

The authors present a case demonstrating the unusual combination of myocardial bridging with a coronary artery aneurysm complicated by acute transient left ventricular dysfunction due to myocardial stunning. The pathophysiology and current insights into myocardial bridging, coronary aneurysms and myocardial stunning are briefly discussed. The literature reveals only one other reported case of coronary aneurysms associated with myocardial bridging. In addition, although there are several reports of angina and myocardial infarction complicating bridging, there is only 1 other report of myocardial stunning specifically.
