Efficacy of the Norwood Operation with a Right Ventricle-Pulmonary Artery Shunt at 1 Month after Bilateral Pulmonary Artery Banding

Right ventricle-to-pulmonary artery shunt related complications after Norwood procedure.

OBJECTIVE The right ventricle-to-pulmonary artery (RV-PA) shunt in the Norwood procedure (NP) for children with hypoplastic left-heart syndrome (HLHS) provides stable early hemodynamics and improves survival in many centers. However, lower pulmonary-to-systemic flow ratio causes early cyanosis and may require earlier second-stage procedure. The aim of the study was to present shunt-related resu...

ST segment depression after Norwood/systemic-pulmonary artery shunt.

Hemodynamic profile after the Norwood procedure with right ventricle to pulmonary artery conduit.

BACKGROUND The balance of systemic, pulmonary, and coronary blood flow after the Norwood operation for hypoplastic left heart syndrome (HLHS) is critical to early survival. We hypothesized that a right ventricle to pulmonary artery conduit (instead of a systemic to pulmonary artery shunt) would result in hemodynamic changes consistent with a more stable balance of systemic, pulmonary, and coron...

Single ventricle with systemic obstruction in early life: comparison of initial pulmonary artery banding versus the Norwood operation.

OBJECTIVES The outcomes of initial pulmonary artery banding (PAB)+/-coarctation repair are compared with the Norwood operation in newborns with single ventricle (SV) and systemic obstruction (SO). METHODS Between January 1987 and July 2000, 22 patients (median age, 12 days) with SV and aortic arch obstruction (AAO), subaortic stenosis (SAS), or both underwent surgery. Two initial surgical app...

Homograft valved right ventricle to pulmonary artery conduit as a modification of the Norwood procedure.

BACKGROUND The use of a right ventricle to pulmonary artery (RV-PA) conduit in the Norwood procedure has been proposed to increase postoperative hemodynamic stability. A valve within the conduit should further decrease RV volume load. We report our clinical experience with this modification. METHODS AND RESULTS From February 2002 through August 2005, we performed 88 consecutive Norwood proced...
