Abstract

Noninvasive techniques for evaluation of myocardial blood supply can be divided into two subgroups. The first subgroup includes Doppler echocardiography, which measures the local blood flow velocity in one of the major coronary arteries supplying a given myocardial region. Color and spectral Doppler techniques are used in transthoracic and transesophageal echocardiography. An accepted simplification of Doppler measurement of coronary blood flow is a measurement not of the volumetric, absolute coronary flow, but only its component i.e. the velocity. The relationship between these two parameters is expressed in the following formula:

Volumetric coronary f1ow=coronary flow velocity × vessel cross-sectional area
