Does Bilateral Pulmonary Artery Banding in Norwood Patients Adversely Affect the Branch Pulmonary Artery Size? An Outcome Comparison with Primary Norwood Patients

Objectives: Bilateral pulmonary artery banding (PAB) is an initial palliation option in the management of single ventricle patients including hypoplastic left heart syndrome (HLHS). PAB yields good results especially in high-risk HLHS patients. However, there is concern with pulmonary artery growth after PAB. In addition, it has been speculated that longer duration of PAB might have a more pronounced negative effect on PA size.
