Hemodynamic Simulation for Congenital Heart Disease
Hypoplastic left heart syndrome (HLHS) is one kind of congenital heart diseases of newborn. The surgeries for HLHS have to be carried out at very early stage. However, currently there are no quantitative standard to evaluate and predict the outcome of the therapy. In this study, computational fluid dynamics (CFD) is introduced simulate the hemodynamics after Norwood surgery; a first stage surge...
متن کاملA New Minimum Order Lumped-Parameter Model of Circulatory System for Patients with Suffered Left and Right-Sided Heart Failure
In this study a new minimum lumped electrical model of total circulatory system through numerical solutions to approximate the response of the human circulatory system was presented. Among five existent ventricular elastances as activity function of heart pumps, a more accurate model was chosen as well as the operation of baroreflex system to accommodate variations in heart rate and systemic va...
متن کاملDrosophila Model of Congenital Heart Diseases
Congenital heart defects (CHD) are the most common birth defects, occurring in about 0.7% of all newborn infants. There are multiple lines of evidence that genetic components are involved in developing CHD pathogenesis. An important aspect in understanding disease mechanisms is that in addition to contributions from a single disease-causing gene (usually seen in many familial cases of CHD), a m...

متن کاملA simulation protocol for exercise physiology in Fontan patients using a closed loop lumped-parameter model.
BACKGROUND Reduced exercise capacity is nearly universal among Fontan patients, though its etiology is not yet fully understood. While previous computational studies have attempted to model Fontan exercise, they did not fully account for global physiologic mechanisms nor directly compare results against clinical and physiologic data. METHODS In this study, we developed a protocol to simulate ...
