Milking-like effect secondary to systolic expansion of a post-infarction left ventricular aneurysm.

Systolic compression of coronary arteries is almost always due to the existence of myocardial bridging. We present a patient with a post-infarction left ventricular aneurysm in whom coronary angiography showed a milking-like effect with systolic compression of the distal left anterior descending coronary artery.
