Abstract

Cardiac performance is intimately connected with the blood dynamics and resultant flow pattern in the left ventricle. This dynamics remains a controversial subject considering the interpretation of phenomena which are observed in ultrasonic echocardiographic and X ray cineangiographic clinical investigations. Moreover, analysis of flow patterns in human cardiac chambers with a bi-directional ultrasonic pulsed Doppler technique through a transcutaneous approach, has been recently shown to be feasible /1, 2/. Nevertheless, in spite of an increasing amount of human clinical data, both under normal and pathological conditions, mitral and aortic valve leaflet kinetics and myocardium mechanical behavior are not fully well understood with reference to their interactions with the intracardiac blood flow.
