standardized data acquisition in transoesophageal echocardiography 29 Fig. 1.35 Transgastric right ventricular inflow and outflow tract during systole (a) and diastole (b) and the corresponding colour-coded views (c, d). Additional comments in the text. Fig. 1.36 Transgastric short-axis views at the mitral valve level. Two slightly different sectional planes of the mitral valve are displayed during systole (a, c) and diastole (b, d). Additional comments in the text.
30 chapter 1 conventional echocardiography—basic principles 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. Fig. 1.38 Mid-oesophageal short-axis view (a) and long-axis view (b) of the descending aorta. Additional comments in the text. 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.
