WebThe early embryonic heart of vertebrates is a simple tubular pump. During the early phases of its development, the initially straight embryonic heart tube becomes transformed into a helically wound loop that is normally seen with a counterclockwise winding. This process … WebAbnormal displacement of the heart loop toward the left is rare and is called levo-looping. Descriptive studies have shown that the lateralization of the heart loop is driven by rotation around its dorsal mesocardium. However, nothing was known on the modes of this process.
