A MULTI-SCALE CFD ANALYSIS OF THE HYBRID NORWOOD PALLIATIVE TREATMENT FOR HYPOPLASTIC LEFT HEART SYNDROME: EFFECT OF REVERSE BLALOCK-TAUSSING SHUNT DIAMETER

摘要

A multiscale model of the neonatal Hypoplastic Left Heart syndrome (HLHS) circulation following the Hybrid Norwood procedure was used to obtain systemic and pulmonary perfusion rates as well as detailed hemodynamics in the aortic arch region. The effects varying degrees of aortic arch stenosis, an obstruction to flow through the mid aortic arch, were studied. Implementation of a 3.0mm and 4.mm reverse-BT shunt (RBTS), a synthetic bypass from the main pulmonary to the innominate artery, and its effects on local and global hemodynamics were also studied.
