Special Issue Information

Dear Colleagues,

Biomedical engineering, which combines the knowledge of several aspects of medical and engineering fields, has received great attention from the scientific research and medical community in recent decades. Many clinicians have considered new simulation software to understand its use for the purposes of treatment optimisation and outcome prediction based on a patient-specific modelling approach. 

Specific clinical applications include the understanding of human pathologies and diseases; the advancement of medical healthcare; and the improvement of diagnosis, therapies, and clinical outcomes. Other applications are related to the sport field. The performance of athletes can be studied and improved using different numerical simulators. 

The development of numerical or hybrid (numerical-hydraulic) models may also help to reduce the number of tests in animals and possibly contribute to the improvement of their wellbeing. Finally, numerical models have been developed to study biological problems, such as stem cell therapy, treatment of tumours, wound healing and microfluidics and diffusion processes.

The use of simulation software based on numerical/hybrid models describing organ or cell behaviour is becoming more popular for educational purposes.

This Special Issue is focused on the numerical modelling of the complex problems in the field of biomechanical and biomedical engineering, which include but are not limited to:

  • Cardiovascular mechanics;
  • Interaction between the cardiovascular system and mechanical assist devices and/or mechanical ventilation;
  • Computational biofluid dynamics;
  • Clinical application of novel numerical algorithms to the biomedical engineering;
  • The use of numerical simulation in education;
  • Tissue and cell mechanics;
  • Numerical methods applied to biomechanics;
  • Computer-assisted surgery and fluid dynamics;
  • Multiscale flow modelling (3D, 1D, and 0D models);
  • Biomechanics in athletics;
  • Movement analysis and biomechanics for endurance sports;
  • Application and impact of numerical models for decision making in sport;
  • Molecular and cell therapies.

As such, high-quality original research papers are welcome.

Membrane artificial lungs (oxygenators) are used in cardiopulmonary surgery as well as, in some cases, in severe lung disease to support the natural lung by means of ECMO (extracorporeal membrane oxygenation). The oxygen and carbon dioxide transfer rates of any oxygenator are usually assessed by considering several blood gas parameters, such as oxygen saturation, hemoglobin concentration, partial pressure of oxygen and carbon dioxide, bicarbonate concentration, and pH. Here, we report a set of semi-empirical equations that calculate such parameters directly from their partial pressures and assess the acid–base balance during ECMO. The implementation of this equation set permits the evaluation of any oxygenator, existing or prototypes in development, as well as the development of clinical decision-making tools for predicting the blood gas state and acid–base balance during surgical interventions and ECMO. The predicted results are then compared with experimental data obtained from in vitro gas exchange investigations with a commercial oxygenator using fresh porcine blood. The high correlation, R2>0.95, between the predicted and the experimental data suggests a possibility of using such empirical equations in the simulation of gas transfer in a cardiopulmonary system with an oxygenator for any venous inlet blood gas data and also for estimating the acid–base balance during such therapy.

Cardiogenic shock is a life-threatening condition consisting of low cardiac output status leading to end-organ hypoperfusion following either acute left or right ventricular failure or decompensation of chronic heart failure. Partial or failed response to inotropic support in the acute phase may require the use of mechanical circulatory support. Although patients supported with different devices such as an IABP, Impella 2.5, or TandemHeart experience stability in the short term, the haemodynamic benefits of each device remain unclear. The aim of this study is to present a direct comparison of an IABP, Impella 2.5, TandemHeart, and combined IABP and Impella 2.5 support in cardiogenic shock to evaluate haemodynamic variables and left ventricular unloading using cardiovascular system modelling and simulation in terms of cardiac function, systemic, pulmonary, cardiac, and cerebral circulations. The simulation results showed that the IABP had a relatively low effect on the haemodynamic variables. Although both Impella 2.5 and TandemHeart improved the total blood flow rates, as well as coronary and cerebral perfusion with the increasing pump operating speed, TandemHeart had a more profound effect on the haemodynamic variables. Combining the IABP and Impella 2.5 also improved the haemodynamics, although at the expense of reverse blood flow in the cerebral circulation. Simulation results showed that TandemHeart support might have a more beneficial effect on the haemodynamics and left ventricular energetics in comparison to the IABP and Impella 2.5. Nevertheless, the combined use of the IABP and Impella 2.5 for short-term support may be considered an appropriate alternative. Full article
