We report here a case of a @entity1 who underwent percutaneous intervention to the left anterior descending artery, complicated by @entity715 formation within the @entity296 distal to the lesion. There was complete angiographic resolution of @entity715 and restoration of the normal antegrade blood flow after infusion of glycoprotein IIb/IIIa antagonist (abciximab). Our observation may suggest that the presence of @entity296 distal to coronary lesions should be considered seriously in preprocedural evaluation of the lesions as a potential risk factor for intracoronary @entity715 formation. The main coronary arteries and the proximal segments of their major branches lie free on the epicardial surface of the heart. However, in some instances these vessels may penetrate into the muscle being surrounded by the myocardium, with the overlying muscle referred to as a "bridge". @entity296 appears to be a @entity154 , due to failure of exteriorization of the primitive coronary intratrabecular arterial network. It occurs in 5-86% of @entity1 in autopsy studies, and it is observed as systolic coronary artery narrowing in 0.5-12% of @entity1 undergoing coronary arteriography. Although the gross anatomist had long recognized that the epicardial coronary artery might on occasion course directly through a segment of cardiac muscle, the physiological significance of this phenomenon was considered benign. This is partly because traditional teaching concerning coronary blood flow delivery to the left ventricular myocardium emphasized the primacy of the diastolic phase of the cardiac cycle. However, @entity296 is not always a benign finding, with recent reports suggesting an association with @entity741 , @entity1188 , @entity2553 , @entity299 , and @entity944 .
