What is the viewing angle for the four-chamber view in TEE?

The four-chamber view in transesophageal echocardiography (TEE) is typically obtained at a viewing angle of 0 degrees. This angle allows for optimal visualization of the left and right atria and ventricles, effectively showcasing the structural and functional aspects of the heart chambers. When the TEE probe is oriented at 0 degrees, it aligns the ultrasound beam directly toward the heart's midline, facilitating a clear and comprehensive view of both atria and all four chambers of the heart simultaneously.

In this position, the echogenic structures of the heart appear prominently, allowing the clinician to assess various conditions such as chamber size, wall motion, and the presence of any structural abnormalities. This view is crucial for evaluations pertaining to cardiac function and overall cardiac anatomy, serving as a foundational perspective for further examination.
