Abstract

Hypoplastic left heart syndrome (HLHS) is rare but serious. It is the most common cause of death from heart disease during the first week of life. With surgical repair or a heart transplant, about 70% of children born with HLHS live for at least 5 years. The purpose of this study is to achieve an optimization of the systemic-topulmonary artery shunt. In this study, computational fluid dynamic (CFD) models were used to determine the velocity profile in a systemic-to-pulmonary artery shunt and we suggest a simplified method of calculating the blood mass flow rate in the shunt based on ultrasound systems. We analyzed the flow characteristic variations and Oscillatory Shear Index (OSI) due to the anastomosis angle and changing shunt diameter.
