Left Atrium by Echocardiography in Clinical Practice: From Conventional Methods to New Echocardiographic Techniques
Figure 8
Left atrial volumes by TomTec 4D echocardiography. (a) After LA full-volume data acquisition, TomTec software displays LA in 3 different apical planes (4-chamber; 2-chamber, long-axis). (b) The endocardial border is surrounded on end-diastolic and end-systolic frames and, if needed, manually corrected. (c) Atrial maximum (max) and minimum (min) volumes are obtained using semiautomated border detection algorithm and displayed in numeric values and in 3D image (in green).
