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...
متن کاملUse of mathematical modeling to compare and predict hemodynamic effects between hybrid and surgical Norwood palliations for hypoplastic left heart syndrome.
BACKGROUND Combining bilateral pulmonary artery banding with arterial duct stenting, the hybrid approach achieves stage 1 palliation for hypoplastic left heart syndrome with different flow characteristics than those after the surgical Norwood procedures. Accordingly, we used computational modeling to assess some of these differences, including influence on systemic and cerebral oxygen deliverie...
متن کاملNorwood Procedure for Palliation of Hypoplastic Left Heart Syndrome: Right Ventricle to Pulmonary Artery Conduit vs Modified Blalock-Taussig Shunt.
Patients with hypoplastic left heart syndrome undergo a series of operations to separate the pulmonary and systemic circulations. The first of at least 3 operations occurs in the newborn period, with a stage I palliation. The goal of stage I palliation is to provide pulmonary blood flow and create an unobstructed systemic outflow tract. Advances in surgical techniques and intraoperative and pos...
متن کاملComparison of Hybrid and Norwood Strategies in Hypoplastic Left Heart Syndrome SURGERY | REVIEW
The Norwood-based strategy for single ventricle palliation has improved with technical innovations and refinements over the last decades; such as regional cerebral perfusion during aortic arch reconstruction [1], placement of a right ventricle-to-pulmonary artery (RV-PA) shunt rather than a systemic-to-pulmonary shunt [2, 3], and the concept of aggressive afterload reduction to maximise oxygen ...
متن کاملRight 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...
