Ex-vivo Isolated Working Heart Model for Cardiac Assessment using PV Loops

Webbparameter. Moreover, using a pressure or flow sensor ensures that LV filling is not limited by inadequate LA atrial inflow. Filling of the LA can be determined by running the equipment without a heart attached and measuring the flow from the LA line. Flow rate of at least 150 ml/min is recommended for a 1g heart. The perfusion fluid WebbPoint 1 on the PV loop is the pressure and volume at the end of ventricular filling (diastole) and therefore represents the end-diastolic pressure and end-diastolic volume (EDV) for the ventricle. As the ventricle begins to contract isovolumetrically (phase b), the mitral valve closes and the LVP increases, but the LV volume remains the same, therefore resulting …
