Adult Echocardiography Practice Exam

Which transducer position is not helpful in evaluating tricuspid valvular flow?

1. Suprasternal

2. Parasternal short axis

3. Left parasternal right inflow view

4. Apical

The correct answer is: Suprasternal

The suprasternal position is typically not helpful in evaluating tricuspid valvular flow because it is mainly used to visualize the great vessels and the aorta rather than the structures of the heart chambers and valves that are essential for assessing tricuspid function. In this position, it is difficult to obtain clear and detailed images of the right atrium, right ventricle, and tricuspid valve, which are necessary for a comprehensive evaluation of tricuspid flow. In contrast, other positions, like the parasternal short axis or the apical views, provide advantageous angles that allow for direct visualization of the tricuspid valve and its associated flow dynamics. The left parasternal right inflow view specifically focuses on the inflow from the right atrium to the right ventricle, making it particularly useful for assessing tricuspid valve function.
