Abstract |
We report 3 patients having a grade II milking effect of the proximal left anterior descending artery (LAD) and suffering from angina. Preoperative myocardial ischemia was demonstrated by stress ECG in all 3 and by pacing and lactates studies in 2. Surgical decompression of the systolically constricted artery has resulted in disappearance of angina, milking, and ischemia. Severe milking of the LAD is a rare entity, probably congenital in origin, capable of producing myocardial ischemia and possibly causing sudden death. More studies regarding its etiology and pathophysiology are necessary. Biopsy of the myocardium surrounding the artery could be useful.
