Abstract
An apparatus () for ex-vivo measurement of performance of a donor heart () has a heart holder () in a receptacle () for holding a human donor heart and a bag () for placement into a left ventricle of the heart. The bag has a bag interior space communicating with an interior space of a fluid tight, compressible and expandable container (. The apparatus further includes a sensor () for measuring compression and expansion of the container. Using the apparatus, cardiac output can be measured by measuring expansion and contraction of the container. A method for ex-vivo measurement of performance of a donor heart is also described. The method may include controlling the preload and/or the afterload.
