In a normal fetal heart, which cardiac chamber is the most anterior?

In the fetal heart, the chamber that lies closest to the chest wall is the right ventricle. The right ventricle forms the majority of the anterior surface, while the left ventricle sits more posterior and toward the left, with the atria positioned higher and more posterior than the ventricles. So, in a normal fetal heart, the most anterior chamber is the right ventricle, not the left atrium. This orientation is important when evaluating the heart in four-chamber views on ultrasound.
