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

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?

Hybrid Procedure in Neonatal Critical Aortic Stenosis and Borderline Left Heart: Buying Time for Left Heart Growth

Infants with “borderline” left ventricles due to congenital aortic valve stenosis may be critically ill soon after birth since the left ventricle may be unable to sustain the complete systemic circulation. In these hearts, the stroke volume of the left ventricle is markedly decreased because of diminutive left ventricular internal dimensions. As the arterial duct closes in the first hours after...

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 ...

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...
