The hypoplastic left heart syndrome (HLHS) is the most common type of univentricular heart. (Figure 15) Not only the left ventricle, but often the aortic valve, ascending aorta and aortic arch are hypoplastic as well. This will redirect blood from the left atrium into the right atrium, where is will be mixed with venous blood and pumped into the right ventricle and pulmonary artery. The whole systemic circulation depends on the shunt from pulmonary artery through the ductus arteriosus into the aorta. When the ductus starts closing the consequences are dramatic, with severe cyanosis and acidosis. | The hypoplastic left heart syndrome (HLHS) is the most common type of univentricular heart.
