Fig. 1.37 Deep transgastric long-axis view during systole (a) and diastole (b) and the corresponding colour-coded views (c, d). Further colour-coded views of a
patient with hypertrophic cardiomyopathy are displayed during systole (e) and diastole (f). Additional comments in the text.

view (a) and long-axis view (b) of the
descending aorta. Additional comments

In the region of the separation of the left subclavian artery, the
probe has to be rotated (10°–60°) to display the descending aorta
in short-axis views ( Fig. 1.38a–b). The aortic arch is displayed
in a short-axis view after rotation of about 90°. Scanning of the
descending aorta is necessary for the detection of plaque ruptures
and other aortic pathologies. If pathological findings are present,
additional long-axis views of the descending aorta should be
documented.
Standard values in transthoracic and
transoesophageal echocardiography
M-mode measurements
M-mode measurements in conventional echocardiography are
mainly performed for analysis of left ventricular dimensions and
wall thicknesses, as well as aortic root and left atrial dimensions.
