Morphology
The meaning is directly and transparently derived from combining 'heart' (the organ) with 'valve' (a flow-control device): it denotes the valve that is part of the heart (including an artificial replacement). This noun–noun compositional pattern is common and cross-linguistically regular, so a B1 learner who knows both constituents will readily understand the MWE.
Etymology
Heart valve is used for an artificial valve because the man-made 'door' replaces the damaged natural valve in the heart and acts the same way, opening to let blood pass and closing to stop it going back. That's why doctors call the device a 'heart valve'.
