Recent advances in imaging modalities used frequently in clinical routine can provide description of the geometrical and hemodynamical properties of the arterial tree in great detail. The combination of such information with models of blood ﬂow in the arterial tree can provide further information, such as details in pressure and ﬂow waves or details in the local ﬂow ﬁeld. Such knowledge maybe be critical in understanding the development or state of arterial disease and can help clinicians perform better diagnosis or plan better treatments. In the present review, the state of the art of arterial tree models is presented, focusing on 1-D wave propagation models. Our development of a generic and patient-speciﬁc model of the human arterial tree permitting to study pressure and ﬂow waves propagation in patients is presented. The predicted pressure and ﬂow waveforms are in good agreement with the in vivo measurements. I will discuss the utility of these models in different clinical applications and potential future developments of clinical interest.
