用3 MHz二维脉冲多普勒超声心动图仪在短轴平面上直接检查主动脉瓣口（主动脉瓣口面积，AVOA）。AVOA用多普勒门控标测，以检测或排除通过记录“是或否”的异常舒张期多普勒信号建立的主动脉瓣反流区（RAVA）的存在。对12例正常人和83例患者（包括40例经主动脉造影证实的主动脉瓣关闭不全患者）进行了研究。对38例经多普勒超声心动图诊断为主动脉瓣关闭不全的患者（诊断敏感性95%，特异性100%），进行RAVA和AVOA平面测量，计算两个指标：RAVA/m2体表面积和RAVA/AVOA比值。这些指数与独立进行的三分量表血管造影分级相关性良好（RAVA的r = .87，RAVA/AVOA的r =.88; p <.001），RAVA/AVOA的每个严重程度等级之间的平均值差异显著性最高（p <.001）。此外，多普勒超声心动图确定了病变的解剖瓣膜部位，我们在手术中确认了该部位。
Direct examination of the aortic orifice at the level of the aortic valves (aortic valvular orifice area, AVOA) in the short-axis plane was performed with a 3 MHz two-dimensional pulsed Doppler echocardiographic apparatus. The AVOA was mapped with the Doppler gate to detect or rule out the presence of a regurgitant aortic valvular area (RAVA) established by recording of abnormal diastolic Doppler signals on a "yes or no" basis. A group of 12 normal subjects and 83 patients, including 40 patients with aortic regurgitation proven by aortography, were investigated with this procedure. In the 38 patients with aortic regurgitation diagnosed by Doppler echocardiography (diagnostic sensitivity 95%, specificity 100%), planimetric measurements of the RAVA and AVOA were performed with calculation of two indexes: the RAVA/square meter of body surface area and the RAVA/AVOA ratio. These indexes correlated well with independently performed angiographic grading on a three-point scale (r = .87 for the RAVA, .88 for the RAVA/AVOA; p less than .001), with highest significance of differences in mean values among each grade of severity found for the RAVA/AVOA (p less than .001). In addition, Doppler echocardiography identified the anatomic valvular site of the lesion, and we confirmed the site during surgery.
