    • Development and Identification of a Closed-Loop Model of the Cardiovascular System Including the Atria 

      Pironet, A.; Revie, J.A.; Paeme, S.; Dauby, P.C.; Chase, J.G.; Desaive, T. (University of Canterbury. Mechanical Engineering, 2011)
      The atria play an important role in cardiac function. The introduction of two chambers representing the atria in an existing model of the cardiovascular system could provide useful information. A previously validated ...
    • Effect of abrupt preload reduction on left atrial and ventricular pressures in a multi-scale mathematical model of the cardiovascular system 

      Pironet, A.; Dauby, P.C.; Kosta, S.; Paeme, S.; Chase, J.G.; Kolh, P.; Desaive, T. (University of Canterbury. Mechanical Engineering, 2013)
      The time-varying elastance theory has been widely used to describe left atrial and ventricular behaviors. However, the applicability of this theory to the left atrium is not fully established. Therefore, we used a different ...
    • Mathematical multi-scale model of the cardiovascular system including mitral valve dynamics. Application to mitral regurgitation 

      Paeme, S.; Moorhead, K.T.; Chase, J.G.; Hann, C.E.; Lambermont, B.; Kolh, P.; D’orio, V.; Moonen, M.; Lancellotti, P.; Dauby, P.C.; Desaive, T. (University of Canterbury. Mechanical Engineering, 2011)
      Background: Valve dysfunction is a common cardiovascular pathology. Despite significant clinical research, there is little formal study of how valve dysfunction affects overall circulatory dynamics. Validated models would ...
    • Mitral valve dynamics in a closed-loop model of the cardiovascular system 

      Desaive, T.; Paeme, S.; Chase, J.G.; Hann, C.E.; Lambermont, B.; Kolh, P.; Moonen, M.; Lancellotti, P.; Dauby, P.C.; Barnett, A. (University of Canterbury. Mechanical Engineering, 2009)
      Introduction: A cardiovascular and circulatory system (CVS) model has been validated in silico, and in several animal model studies. It accounts for valve dynamics by means of Heaviside function to simulate “open on pressure, ...
    • Parameter Identification in a Model of the Cardiovascular System Including the Atria 

      Pironet, A.; Revie, J.A.; Paeme, S.; Dauby, P.C.; Chase, J.G.; Desaive, T. (University of Canterbury. Mechanical Engineering, 2011)
      This research describes the extension of an existing lumped computer model of the cardiovascular system and an associated parameter identification method to the atria. It is found that the introduction of the atria supplies ...
    • A simplified model for mitral valve dynamics 

      Moorhead, K.T.; Paeme, S.; Chase, J.G.; Kolh, P.; Pierard, L.; Hann, C.E.; Dauby, P.C.; Desaive, T. (University of Canterbury. Electrical and Computer EngineeringUniversity of Canterbury. Mechanical Engineering, 2013)
      Located between the left atrium and the left ventricle, the mitral valve controls flow between these two cardiac chambers. Mitral valve dysfunction is a major cause of cardiac dysfunction and its dynamics are little known. ...
    • Simulation of left atrial function using a multi-scale model of the cardiovascular system 

      Pironet, A.; Dauby, P.C.; Paeme, S.; Kosta, S.; Chase, J.G.; Desaive, T. (University of Canterbury. Mechanical Engineering, 2013)
      The quick dynamic insulin sensitivity test (DISTq) can yield an insulin sensitivity result immediately after a 30-min clinical protocol. The test uses intravenous boluses of 10 g glucose and 1 U insulin at t = 1 and 11 ...
    • Structural Model of the Mitral Valve Included in a Cardiovascular Closed Loop Model 

      Paeme, S.; Moorhead, K.T.; Chase, J.G.; Hann, C.E.; Lambermont, B.; Kolh, P.; Moonen, M.; Lancellotti, P.; Dauby, P.C.; Desaive, T. (University of Canterbury. Electrical and Computer EngineeringUniversity of Canterbury. Mechanical Engineering, 2011)
      This research describes the integration of a structural model of the mitral valve in an existing closed loop cardiovascular system (CVS) model.
    • Structural model of the mitral valve included in a cardiovascular closed-loop model: Static and dynamic validation 

      Paeme, S.; Moorhead, K.; Chase, J.G.; Lambermont, B.; Kolh, P.; Lancellotti, P.; Dauby, P.C.; Desaive, T.; Hann, C.E.; Moonen, M. (University of Canterbury. Mechanical Engineering, 2012)
      A minimal cardiovascular system (CVS) model including mitral valve dynamics has been previously validated in silico. It accounts for valve dynamics using a second order differential equation to simulate the physiological ...
