Norwood procedure

The Norwood procedure is a palliative procedure that is the first of three stages in the surgical treatment of hypoplastic left heart syndrome.

The procedure consists of three components:

  • constructing a neo-aorta by side-to-side anastomosis of the main pulmonary artery and ascending aorta, such that the right ventricle supplies the systemic circulation
  • creating a systemic-to-pulmonary shunt to provide some pulmonary blood flow
    • in the classic Norwood procedure, a modified Blalock-Taussig shunt is placed
    • in the Sano modification, a right ventricle-to-pulmonary artery conduit (Sano shunt) is used instead
  • atrial septal resection

History and etymology

William Norwood and associates described the technique in 1980s 2,4.

Congenital heart disease

There is more than one way to present the variety of congenital heart diseases. Whichever way they are categorized, it is helpful to have a working understanding of normal and fetal circulation, as well as an understanding of the segmental approach to imaging in congenital heart disease.
