    A New Cardiovascular Mock Loop Driven by Novel Active Capacitance in Normal and Abnormal Conditions by Mehmet Iscan, Aydin Yesildirek

    Published 2023-01-01
    “…LVVE establishes a dynamic link between left ventricular volume (LVV) and LVC, inherently satisfying the regulatory relationship between left ventricular pressure (LVP) and LVV through a mathematical equation. For the first time, LVVE integration significantly enhances the physiological relevance of hMCL by faithfully replicating FSM responses across diverse conditions, including aortic stenosis (AS), variations in systemic vascular resistance (SVR), and heart rate (HR) variations. …”
