An unusual combination of myocardial bridging and coronary artery aneurysm identified on 64-detector coronary angiography

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.

Triple coronary pathologies complicated by acute cholecystitis

Coronary atherosclerosis, myocardial bridge, and coronary aneurysm are different causes of myocardial ischemia. Patients with cardiac ischemia can be complicated by acute cholecystitis. A 39-year-old man referred with chest pain and cold sweating and scheduled for coronary artery bypass grafting (CABG) because of severe stenosis in right coronary artery, aneurysm of left circumflex artery, and long-segment muscle bridge in the middle part of left anterior descending artery. He developed acute cholecystitis before operation. Concomitant cholecystectomy and CABG was done. He is the first patient with three different coronary pathologies and simultaneous cholecystitis in the English-language literature who was operated on in a single session.
