Outcome of Norwood operation for hypoplastic left heart syndrome

The Norwood procedure, the first surgical step of staged palliation for hypoplastic left heart syndrome (HLHS), is also applied for other complex single ventricle lesions. This study aimed to evaluate the outcome of the Norwood operation in a single center over 4 years and to identify clinical and anatomic risk factors for overall mortality. A retrospective review of the pediatric cardiovascular surgery database was performed to identify infants with HLHS who underwent NP (Norwood procedure) at our institution between January 2007 and December 2011. Our study population consisted of 85 patients with HLHS. Early mortality (30 days postoperative period) between January 2007 and December 2011 for Norwood operation was 7 (8.2%) out of 85 patient, and overall mortality was 24 (28.2%). Our single-center experience shows that the Norwood operation can be performed for complex single ventricle lesions with similarly good early outcomes regardless of the underlying anatomy.
