Configuration of the Neoaortic Root After Chimney Reconstruction in the Norwood Procedure

For hypoplastic left heart syndrome patients undergoing staged reconstruction, the neoaortic root can dilate so that the incidence of neoaortic valve insufficiency increases over time. This article aims to evaluate the outcomes of neoaortic root geometries and valvular function after chimney reconstruction in the Norwood operation in 20 patients. Researchers found that chimney reconstruction did allow patients to avoid significant neoaortic valve regurgitation and preserve conical configuration in the mid-term. However, further studies are needed to evaluate long term outcomes of this form of reconstruction.
