Simultaneous continuous wave Doppler echocardiography, aortic and pulmonary artery pressure measurements were performed during cardiac catheterization in 46 patients with patent ductus arteriosus. Doppler-derived systolic, mean and diastolic transductal gradients correlated well with those measured by catheterization, respectively (r = 0.972, SEE = 6.8 mmHg; r = 0.965, SEE = 5.4 mmHg; r = 0.939, SEE = 6.2 mmHg), and there were clinically acceptable agreements between the two technical measurements. It is concluded that Doppler echocardiography is a reliable and accurate technique for noninvasive estimation of transductal gradients.
在46例动脉导管未闭患者的心导管检查过程中，同时进行了连续波多普勒超声心动图检查及主动脉和肺动脉压力测量。多普勒测得的收缩期、平均和舒张期导管间压差分别与心导管测量值具有良好的相关性（r = 0.972，标准误差估计值[SEE]=6.8 mmHg；r = 0.965，SEE = 5.4 mmHg；r = 0.939，SEE = 6.2 mmHg），并且两种技术测量之间存在临床上可接受的一致性。结论是，多普勒超声心动图是一种用于无创估计导管间压差的可靠且准确的技术。
