[Recording by transcutaneous route of the normal and pathological curves of mitral blood velocity by pulsed emission and modulated reception Doppler technic associated with echocardiography. Preliminary report].
A new method, derived from the Pulsed Doppler Technique is proposed for recording transcutaneously the Mitral Valve flow velocity curves in normal subjects and diseased states. The recorded curves are described and found similar to those obtained experimentally in animals or clinically using CW doppler cardiac catheterization. Characteristic anomalies are found for each type of lesion (stenosis and/or regurgitation) and correlated with the degree of its severity. The authors conclude that this technique may provide a new non-invasive method for diagnosing and assessing Mitral Valve disease.
