In Fig. 89 (p. 111). Typically, turbulence is observed in conditions of jet-like streaming as found in stenoses, regurgitations or high-pressure shunts. These turbulent jets are surrounded by eddies and vortices which may be imaged by a multicolored mosaic-like imaging pattern (see Figs. 4tt" '~ ' . ; ~ . . ~,' 'GE~AR III . . 0 LU-"- "~' . • . • • L \-y''-v .

4 Aorta (Ascending, Arch, Descending) The aorta receives the blood ejected from the left ventricle. Normally the aortic valve opens completely, aligning the leaflets parallel to the blood stream (Figs. 7). The aortic root is, however, not uniformly filled by the streaming blood. Between the aortic leaflets and the wall, in Valsalva's sinuses, there are special flow conditions. Blood flows backwards into each of the three sinuses around the free edges of the leaflets (Fig. 8). This may help to keep the valve in a position ready to close as soon as the left ventricular pressure falls below the aortic pressure with virtually no regurgitation.
