Left-to-right shunts do not cause cyanosis at birth but can ultimately result in heart failure because of volume overload. The clinical significance of left-to-right shunts depends largely on their size and the volume of blood flow through them. Left-to-right shunts typically occur as a result of an atrial septal defect ...
