The Norwood Procedure

The Norwood procedure is the first in a series of three open-heart operations done for a patient with severe heart conditions. The three operations improve the condition of the child's heart, although they do not cure or rebuild the heart completely. The Norwood procedure is performed on pediatric patients with hypoplastic left heart syndrome (HLHS) and other variants of single ventricle heart disease in which the left heart structures do not develop properly.

Surgeons at Children’s have performed more than 300 Stage 1 Norwood procedures since 2000. We have among the best outcomes in the country.

What Should the Norwood Procedure do?

The Norwood procedure helps rebuild the heart to function better. It uses the child's single pumping chamber to support the body while supplying blood-flow to the lungs through a small plastic 'shunt' or tube.

  • Stage I: Provides circulation to the body from the right ventricle
  • Stage II: Allows blood from the upper half of the body to drain directly into the lungs
  • Stage III: Allows the blood from the lower half of the body to drain directly into the lungs
