Coronary angiogram. A) Left coronary system with diffuse disease. B) Thrombotic occlusion of the right coronary artery at the ostium. Note the absence of ipsilateral or contralateral collateral circulation. C) Following reperfusion, the right coronary artery shows marginal flow past the bifurcation due to distal embolization. The posterior descending and posterior lateral coronary arteries are faintly visible.
