Dynamic Systolic Compression of the Left Anterior Descending Coronary Artery by a Postinfarction Dyskinetic Left Ventricular Aneurysm

Abstract

Dynamic systolic compression of the coronary arteries is almost always due to the existence of myocardial bridging that is most commonly localized in the middle segment of the left anterior descending coronary artery. However, it has rarely been reported in patients with pericardial adhesions, tumor, foreign body, or pseudoaneurysms. Only rare case reports exist regarding dynamic coronary compression by a dyskinetic left ventricular aneurysm. We present a patient with a myocardial bridge-like systolic compression of the distal left anterior descending caused by postinfarction dyskinetic left ventricular aneurysm.
