ANGIOGRAPHIC EVIDENCE OF RIGHT CORONARY BRIDGING

Systolic constriction of the left anterior descending coronary artery is a well-recognized angiographic and autopsy finding. The etiology of this phenomenon is an intramural course of the coronary artery. Even though there has been autopsy evidence of an intramural course of the right coronary artery, this rare finding has not been associated with systolic constriction, ''bridging'' on coronary angiography. There is evidence that strenuous exercise can induce ischemia in an intramural left coronary artery. We therefore present a case report of angiograph ic evidence of systolic constriction of the right coronary artery. (C) 1994 Wiley-Liss, Inc.
