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 angiographic evidence of systolic constriction of the right coronary artery.
左前降支冠状动脉的收缩性狭窄是一种公认的血管造影和尸检发现。这种现象的病因是冠状动脉的壁内走行。尽管有尸检证据表明右冠状动脉存在壁内走行，但这一罕见发现与收缩性狭窄并无关联，在冠状动脉造影上也未出现“桥接”现象。有证据表明剧烈运动可诱发壁内左冠状动脉缺血。因此，我们报告一例右冠状动脉收缩性狭窄的血管造影证据的病例。
