The fontan procedure is the third and final surgery to treat hypoplastic left heart syndrome, and usually happens between two and five years of age.
This procedure improves blood flow from the lower body to the lungs, which further decreases the workload of the single ventricle and improves oxygen levels.

Background. Following the norwood procedure for hypoplastic left heart syndrome (hlhs), pulmonary artery distortion and hypoplasia are common and may negatively impact late outcome. The hemi-fontan procedure (hfp) augments the central pulmonary arteries and establishes a connection between the right atrial/superior vena cava junction and the pulmonary arteries, while excluding the inferior vena cava. Methods. The hospital records of all 114 patients undergoing a hfp for hlhs between august 1993 and april 1998 were reviewed to assess patient, procedural, and morphologic determinations of outcome. The results of cardiac catheterization, doppler/echocardiography, 12 lead electrocardiograms, hospital and subsequent course, as well as suitability and outcome for the fontan procedure were analyzed.

The fontan procedure is a type of open-heart surgery. Children who need this surgery usually have it when they’re 18–36 months old.

Infants born with hlhs may have lifelong complications, requiring follow-up visits with a cardiologist to monitor progress. Children with hlhs often take long-term cardiac medicines that help the heart work as efficiently as possible and undergo frequent testing to monitor heart health. If the heart becomes weak over time, a heart transplant may be necessary. Children who undergo a heart transplant will need to take medication for the rest of their lives to help prevent the body from rejecting a new heart. An adult who had a fontan procedure as a child may experience specific problems that require ongoing monitoring by a cardiologist.

Hlhs; aortic and mitral atresia with hypoplastic left heart syndrome; congenital heart – hypoplastic left heart; cyanotic heart disease – hypoplastic left heart description hypoplastic left heart syndrome (hlhs) is a rare congenital heart defect in which the left side of the heart is severely under-developed. The structures of the heart that are usually affected include the mitral valve, left ventricle, aortic valve and the aorta. Because the left side of the heart is unable to send enough blood to the body, the right side of the heart must maintain the circulation for both the lungs and the body. This extra work eventually.
Hypoplastic left heart syndrome (hlhs) is a complex and rare heart condition. Children with hlhs have a combination of related heart problems. A healthy heart is a strong, muscular pump that pushes blood through the circulatory system to carry oxygen and nutrients to the body. The heart has four chambers — two on the right and two on the left. Blood is pumped through these chambers and regulated by valves that open and close like tiny doors, so that blood can move in only one direction. After its trip through the body to deliver oxygen, blood is a blue color because it’s no longer oxygen-rich.
Overview[ edit ] failure to treat hypoplastic left heart syndrome can be fatal for the infant. Surgical therapy is the only true way to treat and permanently fix hypoplastic left heart syndrome. Two main methods exist for treatment: transplantation and a three-stage surgical procedure. Surgery[ edit ] without treatment, hypoplastic left heart syndrome (hlhs) is fatal, but with intervention, an infant may survive. A pediatric cardiothoracic surgeon may perform a series of operations or a full heart transplant. Because these operations are complex and need to be individualized for each patient, a cardiologist must assess all medical and surgical options on a case-by-case basis.
