Differentiating the ventricles on a fetal echo relies on how their interiors and valves look, not just their position. The right ventricle typically shows coarse trabeculations inside its cavity and is anchored by the tricuspid valve annulus. In contrast, the left ventricle has a smoother endocardial surface with fewer prominent trabeculations, and its base is defined by the mitral valve annulus. Additionally, the left ventricle usually appears more conical with a defined apex and thicker walls, which helps distinguish it from the crescent-shaped right ventricle. In practical terms, these texture and valve differences are the most reliable cues across standard views such as the four-chamber and LV outflow tract.

The other descriptions don’t fit normal anatomy: one statement reverses textures between the ventricles, another suggests walls are indistinguishable, and another assigns a bicuspid valve to the right ventricle—none align with how these chambers are actually structured.
