A total of 139 patients(pts) and 10 normals were studied with a complete two-dimensional (2D), Mmode and Doppler echocardiographic examination, 20 pts (14%) had aortic regurgitation with a peak regurgitatant velocity of 2.3±1.2m/s, pandiastole in 90% pts and regurgitant pressure gradient of 26±27mmHg.No aortic regurgitation was detected by these techniques in 10 normals. The diagnosis of aortic regurgitation by 2D Doppler echocardiography was found to be the highest sensitivity and specificity as compared...

The diagnosis of aortic regurgitation by 2D Doppler echocardiography was found to be the highest sensitivity and specificity as compared with that by clinical auscultation, M-mode and 2D echocardiograpiiy alon(?)

本研究报道了从139例心脏病人中经二维多普勒超声心动图测得的20例(14%)主动脉返流和另10例正常人的资料。二维多普勒超声测得本组病人异常返流流速为2.3±1.2m/s,90%分布时相占全舒张期,估算的返流跨瓣压差为26±27mmHg,最高达100mmHg,而10例正常人均未发现主动脉返流的多普勒血流证据。为评价诊断主动脉返流的灵敏度,将所得多普勒资料与临床听诊、单纯二维超声显象和M型超声心动图异常表现作了对比。结果表明,近代二维多普勒超声心动图对诊断主动脉返流具有最高的灵敏度和特异性。

To determine whether the patterns of left ventricular filling may be influenced by the relative wall thickness (RWT) in arterial hypertension, the transmitral blood flow parameters and the RWT were evaluated using pulsed wave Doppler and Mmode echocardiography in 60 hypertensive patients and 30 control subjects. The hypertensive group was divided into two subgroups on the basis of h/r value (mean+2SD of normal value observed in the control group). One subgroup consisted of 28 patients with normal h/r (<0.4)...

To determine whether the patterns of left ventricular filling may be influenced by the relative wall thickness (RWT) in arterial hypertension, the transmitral blood flow parameters and the RWT were evaluated using pulsed wave Doppler and Mmode echocardiography in 60 hypertensive patients and 30 control subjects. The hypertensive group was divided into two subgroups on the basis of h/r value (mean+2SD of normal value observed in the control group). One subgroup consisted of 28 patients with normal h/r (<0.4) and the other consisted of 32 patients with increased h/r (>0.4). The peak flow velocity (PeakE) and the deceleration half-time (DHT) of early mitral flow were significantly different between the two subgroups. In the hypertensive group, significant correlations were demonstrated between the RWT and the PeakE (r=-0.742, P<0.001), DHT(r=0.705, P<0.001); and poor correlations were found between the left ventricular mass (LVM) and the PeakE (r=-0.425, P<0.001), DHT(r=0.324, P<0.001). These data indicate that the influence of RWT upon the patterns of left ventricular filling is obvious in Patients with hypertension.

应用脉冲多普勒测量60例高血压病患者及30例正常人二尖瓣血流参数,采用M型超声心动图测量其相对室壁厚度(RWT),以正常人RWT值均数加二倍标准差将高血压病患者分为RWT正常组与RWT增大组。结果发现:早期充盈参数PeakE、DHT在高血压病两组间差异显著。相关分析表明:高血压病患者RWT与PeakE、DHT相关良好:而左室重量(LVM)则与PeakE、DHT相关不良。结果表明:高血压病患者RWT对其早期充盈参数PeakE、DHT有较为明显的影响。

Seven cases of atrial septal aneutysm (ASA) were found and studied by echocardiography.Mmode echocardiography revealed that the membrane of ASA showed regular and phasic undulation in cardiaccycle.2-DE showed that the mid-Part of the atrial septium became thin and protruded into right or left atrium, or waved between the two, the amplitude ranged from 7 to 19 mm (mean 11.5±4. 0 mm),the hasal diameiter varied from 21. 6 to 34 mm(mean 27. 2± 3. 8 mm);the multiple sections (section 4,9,11, 15) can beused...

Seven cases of atrial septal aneutysm (ASA) were found and studied by echocardiography.Mmode echocardiography revealed that the membrane of ASA showed regular and phasic undulation in cardiaccycle.2-DE showed that the mid-Part of the atrial septium became thin and protruded into right or left atrium, or waved between the two, the amplitude ranged from 7 to 19 mm (mean 11.5±4. 0 mm),the hasal diameiter varied from 21. 6 to 34 mm(mean 27. 2± 3. 8 mm);the multiple sections (section 4,9,11, 15) can beused to detect the ASA. but the best ones were parasternal, subcostal four chamber views. CDFI showedthat the color now went around the bulge of ASA in right atrium. then entered into right ventricle, in theleft the now presented swirling and dimming within ASA. The present study suggests that 2-DE should beconsidered the gold stantard technique for the diagonsis of ASA.

对7例房间隔膨出瘤(ASA)进行超声心动图研究.结果发现,①M型:ASA膜随心动周期呈规律性摆动,但不直观;②二维超声心动图(2-DE):房间隔中间变薄(多位于卵圆窝),呈袋状膨向左或右房、或摆动于两房间,其幅度为7~19.5mm(11.5±4.0mm),基底径为21.6~34.0mm(27.2±3.8mm),胸骨旁四腔、剑下四腔、心尖四腔和心底短轴主动脉瓣水平面可探查到,以前两切面最好;③彩色多普勒:血流于右房内绕过膨出袋进入房室口,左房在ASA内呈回旋状,色彩暗淡。提示:2-DE是活体诊断ASA的最佳手段,其敏感性和特异性高,应为诊断ASA的金标准.
