The lecture deals with methodological aspects and diagnostic potential of the use of novel ultrasound technologies -- transesophageal and transthoracic doppler ultrasonography of coronary arteries for noninvasive assessment of coronary blood flow and coronary reserve. It contains detailed description of technique of visualization of coronary arteries from transesophageal and from transthoracic approaches and interpretation of dopplero-graphic parameters of laminar and turbulent coronary flows. Diagnostic role of the use of contrast echo imaging of coronary arteries is also discussed and dopplero-graphic criteria of occlusion and hemodynamically significant coronary artery stenosis as well as characteristics of normal and lowered coronary reserve are presented.
