Coarctation of the Aorta (CoA) is one of the most serious congenital heart defects in newborns. Approximately 30% of cases of CoA associated with aortic arch hypoplasia (AAH). The end-to-side aortic anastomosis (ESAA) is an effective surgical procedure to be performed for correction of CoA with AAH. In this study, the approach of computational fluid dynamics (CFD) was used to investigate the hemodynamics...
This study evaluated the performance of a centrifugal blood pump designed for the children with heart failure. In this work, to better understand the hemodynamic effects of LVAD outflow-graft anastomosis location, a 3D blood pump model is constructed and patient-specific of ventricular volume is considered. The aim of the research is to observe the impact of the physiological waveform, the periodic...
Pulmonary artery banding (PAB) is a commonly used palliative procedure to restrict excess pulmonary blood in certain congenital heart diseases. However, many associated long-term hemodynamic problems still remain unsolved over the years. In this study, we utilized the method of computational fluid dynamics (CFD) to investigate the hemodynamic effects of PAB on patient-specific pulmonary flow before,...
To treat cyanotic congenital heart defect, modified Blalock-Taussig (mB-T) shunt is an effective procedure used in clinic. The pulmonary artery is bridged by a conduit with the systemic circulation to increase the flow of blood. Here, we report on three-dimensional (3D) hemodynamic analysis of the effects of conduit anastomosis angle on pulmonary flow. A 3D model based on post-operative medical images...
