The method for evaluating right ventricular and pulmonary artery systolic pressures by subtracting the systolic pressure gradient across the ventricular septal defect from the cuff systolic blood pressure is documented. To confirm the reliability and accuracy of this method, simultaneous continuous wave Doppler echocardiography and left and right cardiac catheterization were performed in 66 patients with congenital ventricular septal defects. The comparisons between the Doppler-derived right ventricular or pulmonary artery systolic pressures and those measured by catheterization yielded an excellent correlation (r = 0.969, y = 1.035x - 3.627, SEE = 8.2 mm Hg, p < 0.001 and r = 0.972, y = 1.012x - 2.904, SEE = 7.6 mm Hg, p < 0.001), respectively. There was a close agreement between the Doppler-derived right ventricular or pulmonary artery systolic pressures and those measured by catheters, and the differences between the two measurements did not differ significantly from zero. It is concluded that Doppler echocardiography offers a reliable and accurate method for noninvasive assessment of right ventricular and pulmonary artery systolic pressures in patients with ventricular septal defects.
记录了通过从袖带收缩压中减去室间隔缺损处的收缩压梯度来评估右心室和肺动脉收缩压的方法。为了证实该方法的可靠性和准确性，对66例先天性室间隔缺损患者同时进行了连续波多普勒超声心动图检查以及左右心导管检查。多普勒测得的右心室或肺动脉收缩压与导管测量值之间的比较显示出极好的相关性（分别为r = 0.969，y = 1.035x - 3.627，标准误 = 8.2 mmHg，p < 0.001和r = 0.972，y = 1.012x - 2.904，标准误 = 7.6 mmHg，p < 0.001）。多普勒测得的右心室或肺动脉收缩压与导管测量值之间具有密切一致性，且两种测量值之间的差异与零无显著差异。结论是，多普勒超声心动图为无创评估室间隔缺损患者的右心室和肺动脉收缩压提供了一种可靠且准确的方法。
