![]() However, the rate of entry of contrast into the vessel distal to the obstruction and/or its rate of clearance from the distal bed is perceptibly slower than its entry into and/or clearance from comparable areas not perfused by the culprit vessel (eg, the opposite coronary artery or coronary bed proximal to the obstruction)Ĭomplete perfusion antegrade flow into the bed distal to the obstruction occurs as promptly as into the bed proximal to the obstruction and clearance of contrast material from the involved bed is as rapid as from an uninvolved bed in the same vessel or the opposite artery Partial reperfusion the contrast material passes across the obstruction and opacifies the coronary bed distal to the obstruction. Penetration without perfusion the contrast material passes beyond the area of obstruction but “hangs up” and fails to opacify the entire coronary bed distal to the obstruction for the duration of the cine run No perfusion no antegrade flow beyond the point of occlusion TFG, a grading system for epicardial coronary flow Customer Service and Ordering Informationĭefinitions of the TFG and the TMPG Systems Grade.Stroke: Vascular and Interventional Neurology.Journal of the American Heart Association (JAHA).Circ: Cardiovascular Quality & Outcomes.Arteriosclerosis, Thrombosis, and Vascular Biology (ATVB). ![]()
