Computer and Physical Modeling of Blood Circulation Pump Support for a New Field of Application in Palliative Surgery

Abstract: Objectives One of the most popular palliative procedures performed to increase pulmonary blood flow in children with congenital heart defects is a shunt operation (Blalock-Taussig graft or Glenn procedure), which creates the new blood channel to the pulmonary artery. The main problem with this kind of surgery is poor shunt effectiveness and the lack of possibility to regulate the flow. The aim of this work is to use advanced computer simulation methods to study the effectiveness of a new idea to introduce a sm… Show more

“…Currently, computer fluid dynamics have been increasingly used to study the postoperative haemodynamics of SPS [3]. They allow for the comparison of the haemodynamic characteristics of different shunt configurations [4] and studying the effects of different anastomosis methods on the haemodynamics of the MBTS [5].…”

“…This model must represent physical reality with enough precision so that the answer to desired clinical question is robust and meaningful. Existing tools for validation include comparison of the results to in-vitro data 63,64,[69][70][71] using PIV and dye visualization with stand-alone models or mock-circuits, to in-vivo measurements in animals 48 or in humans 65 . In the latter, for example, velocity results can be compared to MRI data at a slice that was not used to create the numerical results 72 .…”

“…3 Finally, they showed decreased ventricular stroke work with comparable systemic flow; however, neither the impact of ventriculotomy on ventricular performance nor the effect of systemic and pulmonary vascular resistances on ventricular function was investigated. 77 Mathematical models for both atria and the single ventricle are similar, with the difference lying on the value parameters within each model when we compare mBT and RV-PA shunt. For the 3 cardiac chambers (cc), time-varying elastance describes systolic and diastolic pressure-volume relationships, with a minimum value of 0 at diastole and 1 at systole.…”
