Wave intensity analysis in the ventricles, carotid and coronary arteries – What has been learnt during the last 25 years?: Part 2

Christina Kolyva, Ashraf W. Khir


Wave intensity analysis (WIA) was introduced 25 years ago for the study of arterial wave travel and has since been established
as a powerful tool for the investigation of cardio-vascular interaction. Despite the complex mathematical derivation of the
method, the implementation is simple. As a time-domain technique, WIA enables the direct association between waves
and events during the cardiac cycle. Furthermore, it enables the separation of the pressure (or diameter), velocity and wave
intensity waveforms into their forward and backward components, and provides a means for the determination of the timing
and magnitude of waves of different origins. Hemodynamic questions at several locations along the vascular tree have been
investigated with WIA. Part 2 of this review will focus on the physiological and clinical findings to which WIA has contributed,
through clinical and in vivo studies in the ventricles and in the coronary and carotid arteries.
