A new pulsed Doppler mapping technique has been used to measure the severity of aortic valve stenosis. The Doppler examination was performed at the site of the aortic orifice in the parasternal short axis echocardiographic view and the method was based on the detection of the area of systolic flow through the stenotic orifice. This area was derived by planimetry and the measurements obtained by the Doppler method were compared with the aortic valve area calculated at catheterisation according to the Gorlin formula. The method was applicable in 41 of the 44 patients studied. The Doppler data were consistent with the haemodynamic measurements even in patients with decreased cardiac index. It is concluded that this new application of the flow mapping procedure is reliable and is easily applied to adult patients with a wide range of clinical conditions.
一种新的脉冲多普勒映射技术已被用于测量主动脉瓣狭窄的严重程度。多普勒检查是在胸骨旁短轴超声心动图视图中的主动脉口部位进行的，该方法基于检测通过狭窄口的收缩期血流面积。该面积通过平面测量法得出，并将多普勒方法获得的测量结果与根据戈林公式在导管插入术中计算出的主动脉瓣面积进行比较。在所研究的44例患者中，该方法适用于41例。即使在心脏指数降低的患者中，多普勒数据也与血流动力学测量结果一致。得出的结论是，这种血流映射程序的新应用是可靠的，并且很容易应用于具有广泛临床情况的成年患者。
