Abstract
Interpretation of such common phenomena as left ventricular filling and mitral valve opening or closure is still obscured by disparity between hydrodynamic models, physiological experiment and clinical investigation. Problems such as the anteriority of full mitral opening versus peak mitral flow variations, the respective role of local, viscosity-dominated, or convective vortex formation, or breaking of a jet mechanism for valve closure, remain unsolved (1, 2, 3). The multiple scanning pulsed Doppler velocimetry of the heart, an atraumatic, external, clinical investigation could open a new field of approach of the phenomena related to blood flow in the cardiac cavities in undistorted physiological conditions. This technique, in its present stage, remains semi-quantitative, and of limited applicability and performance; thus our observations concerning the left ventricular rapid filling phase do not pretend to solve any pendant problems, but to demonstrate the feasibility of the method.
