Abstract
Coronary flow reserve can be determined echocardiographically in the LAD in about 90 % and in the RCA in more than 80 % of patients respectively by the use of modern high-resolution ultrasound equipment. For this purpose either high frequency fundamental imaging or echo-contrast enhanced harmonic Doppler technology is used. The main advantage of the method lies in its noninvasiveness and the lack of radiation exposure. In combination with coronary morphologic findings obtained from heart catheterization, CFR is helpful in the planning of further invasive procedures for coronary artery disease and in the estimation of the prognosis of such procedures. The functional status after PTCA of LAD/RCA or mammary bypass surgery can be evaluated during follow-up monitoring. Alteration in the coronary microcirculation can also be discovered in a non-invasive way, improvement of microcirculatory disorders by adequate therapy can be assessed by serial measurements of CFR.
