Liu J, Yang Z, Wu X, Huang Z, Huang Z, Chen X, Liu Q, Jiang H, Zhu Q. Exp Anim. Small VSDs are often asymptomatic. As a result, the shunt reverses and becomes right-to-left. Because of the deoxygenated blood crossing over into systemic circulation, the baby presents with early cyanosis. Because of a failure of neural crest cell migration, the conotruncal ridges are not able to form, resulting in this defect, which results in the deoxygenated blood from the right ventricle mixing with the oxygenated blood from the left ventricle, causing cyanosis.
