Question

Which of the following statements best characterizes the TEE mid-esophageal four-chamber view?

A. It is the preferred view to monitor LVOT compression during chest compressions
B. It is commonly used to assess LVEF
C. It is the preferred view for visualizing the ascending aorta

Answer 1

The best characterization of the TEE mid-esophageal four-chamber view is that it is commonly used to assess left ventricular ejection fraction (LVEF), as this view provides a clear image of the heart's chambers for evaluation of structure, valve function, and measurement of cardiac output.

Step-by-step explanation:

The statement that best characterizes the TEE mid-esophageal four-chamber view is that it is commonly used to assess LVEF (left ventricular ejection fraction). The TEE (transesophageal echocardiogram) offers a close and clear view of the heart chambers, including the left atrium, the left ventricle, right atrium, and right ventricle, from an esophageal position.

The left ventricle is the major pumping chamber for the systemic circuit, which ejects blood into the aorta through the aortic semilunar valve. This critical role makes the assessment of its function very important, and calculating the LVEF provides an indication of the heart's pumping efficiency. The mid-esophageal four-chamber view, obtained during TEE, is especially valuable for evaluating the heart's structure and valvular function, as well as other conditions.
