What describes the Coanda Effect in echocardiography?

The Coanda Effect in echocardiography refers to the phenomenon where a fluid jet (such as blood flow) adheres to and follows the contour of a nearby wall or surface, which is often seen in the context of ventricular function and flow dynamics. This effect can lead to the "wall hugging" behavior of blood flow as it moves along the walls of the heart or blood vessels, which is particularly significant in understanding flow patterns within the chambers.

In echocardiographic assessments, recognizing the Coanda Effect is critical for interpreting how blood flows in relation to the geometry of the heart chambers, especially during systole and diastole. This effect can help clinicians make better assessments of flow patterns, turbulent flow, and potential impacts on valve function or chamber interactions. Thus, describing the Coanda Effect as a "wall hugging effect" accurately captures its essence in the context of echocardiography.
