文摘The left anterior descending （LAD） coronary artery is the main vessel of human coronary circulation, and life-threa- tening consequences are seen when flow in this area is im- paired, Noninvasive measurement of coronary flow re- serve （CFR）, defined as the ratio of maximal to baseline coronary blood flow, has been repeatedly shown to be a feasible technique by ultrasound transthoracic Doppler （TTD） both in the LAD and, with some limitations, in the posterior descending （PD） coronary artery.
