Modified apical four chamber view transesophageal echocardiogram

Panel A: Horizontal (0º) imaging from the fundus of the stomach with maximum flexion results in a modified "apical four chamber" view of the heart. Seen are the right ventricle (RV), mitral valve (MV), left ventricle (LV), right atrium (RA), and left atrium. Panel A: Slight anterior rotation of the probe permits imaging of the left ventricular outflow tract (LVOT) and the aortic valve (AoV). Continuous wave, pulsed, or color Doppler examination may also be performed from this orientation. Panel C: In some patients, extensive portions of the ascending aorta (AAo) may be seen.
