It is the most complex cardiothoracic surgery performed in newborns, one in which surgeons literally construct a new, larger aorta for babies born with hypoplastic left heart syndrome (HLHS). Called the Norwood procedure, it must be done within the infant’s first week of life, followed by a second surgery when the baby is three to six months, and a third at age four or five.
The CDC estimates that 1.2 million people in the United States have chronic Hepatitis B (HBV) but two-thirds do not know they are infected. These unaware patients can have clinically silent infections for decades until developing cirrhosis, end-stage liver disease, or hepatocellular carcinoma (HCC). HBV is transmitted by percutaneous or mucosal exposure to blood or body fluids of an infected person, such as from an infected mother to her newborn during childbirth, through close personal contact within households, through unscreened blood transfusion or unsafe injections in health- care settings, through injection drug use, and from sexual contact with an infected person.
