An<unk> , is a class of congenital heart<unk> s. In these, blood is shunted (flows) from the left side of the heart to the right side of the heart, most often due to a structural<unk>  (hole) in the interventricular septum. People often retain normal levels of oxyhemoglobin saturation in systemic circulation. This term is outdated, because a person with an<unk>  may show cyanosis (turn blue due to insufficient oxygen in the blood).
