What is the Norwood Procedure?

NorwoodSano

 

 

The Norwood Procedure is the first surgery for all HLHS babies and usually occurs sometime during the first week of birth.  It is the most complex and highest-risk procedure that an HLHS baby will go through.  Since the heart’s left side does not pump well, the heart is rebuilt so the right side of the heart becomes the main pumping chamber.

The blood vessel leaving the right side of the heart called the pulmonary artery is divided. The far end (the end closest to the lungs) is sewn shut. The near end (the end closest to the heart is sewn into the aorta, which is the large blood vessel leaving the left side of the heart. A patch is sewn in this area to make the “new aorta” or neo-aorta bigger and stronger. Now all the blood leaving the heart goes from the right side of the heart through the pulmonary valve and out to the body through the new aorta.  The wall between the heart’s two upper chambers is removed. This allows red blood coming back from the lungs to flow from the left upper chamber to the right upper chamber. The blood then goes to the right lower chamber and out to the body.

After the Norwood, the right ventricle pumps blood to both the lungs and the body. The Norwood procedure re-routes the blood flow around some of the defective areas of the heart by creating new pathways for blood circulation to and from the lungs.  Nolan will be having a variant of this procedure called the Norwood-Sano, which means that a Sano shunt is being utilized.  The Sano Modification of the Norwood involves the placement of a conduit (light blue tube in the picture above) between the pulmonary artery and the right ventricle.

The recovery period for the Norwood procedure averages 3 to 4 weeks, but please don’t be surprised if it’s longer (you’ll see).  I can’t stress enough how serious of a procedure the Norwood is: it’s not a simple 1-hour fix, and it’s only the first of 3 surgeries an HLHS baby will need.
