With the Karlsruhe Heart Model (KaHMo) we aim to share our vision of integrated computational simulation across multiple disciplines of cardiovascular research, and emphasis yet again the importance of Modelling the Human Cardiac Fluid Mechanics within the framework of the international STICH study. The focus of this work is on integrated cardiovascular fluid mechanics, and the potential benefits to future cardiovascular research and the wider bio-medical community.

In the second edition of the article a virtual heart modelsimulating the flow in the active left human ventricle andatrium is presented. Because in vivo myocardium data is notavailable, the movement of the active ventricle and its atriumis given by three-dimensional, time-dependent invivo image dataof a nuclear spin MRI tomograph. The passive part of the virtualheart model consists of a model aorta and of two-dimensionallymodelled heart valves. As the flow is actively driven by theventricle and atrium, a coupling off low and structure isnecessary to take into account the deviation of the aorta andthe closing and opening of the heart valves. This coupling isreplaced by the movement given by MRI tomograph and ultrasonicDoppler echocardiography, since we focus on the flow simulationin the left pumping ventricle. The flow simulation is performedby a validated commercial software package that uses the finitevolume method. The flow resistance of the circulation throughthe body is taken into account with a simplified circulationmodel. The article shows how the virtual heart model can be usedto predict flow losses and flow structures due to pathologicalventricle contraction defects. It provides as an example theflow simulation of an unhealthy human ventricle with ananeurysm. The flow structure and flow losses are consideredbefore and after surgery.
We present a virtual heart model simulating the flow in the left human ventricle and in the aorta. Because of the lack of in vivo structure data of the human ventricle, the active ventricle movement is given by a time-dependent ventricle model that is derived from in vivo image data of a nuclear spin MRT tomograph of a healthy human heart. The passive part of the virtual heart model consists of a model aorta and vena cava, and of heart valves. As the movement is due to the flow in the inactive region of the heart, a coupling of flow and structure is necessary in the model to take into account the deviation of the aorta and the closing and opening of the heart valves. The flow calculation is performed with a finite volume method, while the structure of the aorta is calculated using the finite element method. The flow resistance of the time simulation in the body is taken into account with a circulation model. In the outlook of the article, we show how the virtual heart model can be used to predict flow losses due to pathological ventricle contraction defects in an unhealthy human heart.
Drawing on his background as an economist and a specialist on the Yugoslav system of workers' self-management, Janez Prasnikar analyzes an extraordinary amount of dispersed information on the experience with workers' participation in thirteen developing countries.
