Web8 de mai. de 2024 · The heart tube continues to elongate, and begins looping at around day 23 of development. The bulbus cordis moves ventrally, caudally, and to the right (forward, down and right), and the caudal portion – the primitive ventricle – moves dorsally, cranially and to the left (backwards, up and left). 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.
