Basic Transthoracic Echocardiographic Imaging

In the adult transthoracic echocardiographic (TTE) imaging, a standard series of cross-sectional anatomical views are recommended by the American Society of Echocardiography (ASE).

There are two major obstacles for ultrasound beam transmission: 1) bony chest wall, 2) air-filled lungs. Specific ultrasound transducer positions on the chest wall are required in order to perform optimal examination.

Four primary transducer positions or “windows” are recommended. For patients with normal levocardia, the examination begins at (1) the left parasternal window, followed by the apical window, (3) the subcostal or subxiphoid window, and (4) the suprasternal notch window

A4C(Apical Four Chamber), A5C(Apical Five Chamber), A2C(Apical Tho Chmaber), A3C(Apical Three Chamber)

In this blog post, I will try to explain the “windows” of the echocardiographic imaging through drawings
