Abstract

In the last few years, the combined pulsed-Doppler echocardiographic technique, by providing a means of recording blood flow velocity patterns at various points in the heart cavities and great vessels, has led to a new noninvasive method for diagnosing and assessing cardiac valvular disorders and shunts [3, 4, 5, 6, 11, 12, 13]. The original combined one-dimensional (1 D) apparatus has been replaced recently by a two-dimensional (2D) unit in order to improve performance. Instead of using two separate transducers, as in the first 2D units [2, 10], the one we use in our laboratory employs a single transducer for both techniques [7, 8]. This paper reports the results of a comparative study using 1D and 2D pulsed-Doppler echocardiographic velocimetry (PDEV) sequentially on a group of patients with valvular heart disorders.
