The Norwood procedure for hypoplastic left heart syndrome.

Since the introduction of the Norwood procedure for surgical palliation of hypoplastic left heart syndrome in 1983, refinements have been made to the original procedure to improve patient outcomes while still accomplishing the original goals of the procedure. One of these refinements has been the introduction of regional selective perfusion to limit the duration of circulatory arrest times and ...

Modified Norwood procedure for hypoplastic left heart syndrome.

BACKGROUND Since June 1994, we have used a modification of the Norwood technique in 13 patients presenting with the hypoplastic left heart syndrome or similar variants. METHODS This technique involves coarctation repair, arch reconstruction, and creation of a neo-ascending aorta using autologous great vessel tissue only. Pulmonary blood flow is provided by a central shunt of 3.0- to 4.0-mm Go...

Growth of left heart structures following the hybrid procedure for borderline hypoplastic left heart.

AIMS The 'hybrid' procedure is an alternative to the Norwood operation in classical hypoplastic left heart syndrome to support the systemic circulation until subsequent palliation. This approach has been extended to infants with the borderline development of left heart structures. We investigated whether or not a hybrid procedure for 'borderline' cases of underdevelopment of the left heart woul...

Hypoplastic Left Heart Syndrome: Why Use a Hybrid Procedure?

Hypoplastic left heart syndrome

Hypoplastic left heart syndrome (HLHS) refers to the abnormal development of the left-sided cardiac structures, resulting in obstruction to blood flow from the left ventricular outflow tract. In addition, the syndrome includes underdevelopment of the left ventricle, aorta, and aortic arch, as well as mitral atresia or stenosis. HLHS has been reported to occur in approximately 0.016 to 0.036% of...
