Abstract
A system for studying a beating explanted heart comprises a fluid inflow circuit configured for coupling to an explanted heart to direct fluid for flowing into a ventricle of the heart, and a fluid outflow circuit configured for coupling to an explanted heart to direct fluid flowing out of the ventricle of the beating heart. A flow meter coupled with the inflow circuit measures the inflow rate of fluid into the heart ventricle and a flow meter coupled with the outflow circuit measures the outflow rate of fluid out of the heart ventricle. A processing system converts the inflow and outflow rates into incremental volume changes in the volume of the heart ventricle and adds and subtracts the incremental volume changes from a relative volume of the heart ventricle to study volume changes in the explanted heart while it is beating.
