超声多普勒和心导管评估先天性心脏病介入治疗前后肺动脉高压的相关性分析

Doppler ultrasound and cardiac catheterization assess congenital heart before and after treatment of pulmonary hypertension

目的评价连续多普勒超声心动图测定合并肺动脉高压的先天性心脏病患儿肺动脉收缩压的准确性。方法以47例合并肺动脉高压的先天性心脏病患儿作为研究对象,分别应用连续多普勒超声心动图和心导管在术前、术后测量肺动脉收缩压,比较两者的相关性。结果术前连续多普勒超声心动图和心导管测得的肺动脉收缩压分别为(45.89±15.04)mmHg和(46.70±18.84)mmHg,术后分别为(35.17±11.08)mmHg和(33.09±13.74)mmHg,两者差异均无统计学意义(术前t=0.43,P>0.05;术后t=1.54,P>0.05)。连续多普勒超声心电图和心导管测得的肺动脉收缩压呈正相关(术前r=0.748,P<0.01;术后r=0.795,P<0.01)。结论连续多普勒超声心动图可较准确地评估合并肺动脉高压的先天性心脏病患者的肺动脉收缩压,具有重要临床应用价值。

Objective To evaluate the accuracy of the pulmonary artery systolic pressure in patients with congenital heart disease combined pulmonary hypertension by continuous Doppler echocardiography. Methods 47 patients were selected in this study who were congenital heart disease combined pulmonary hypertension as the research objects, preoperative and postoperative pulmonary artery systolic pressure were measured using continuous Doppler echocardiography and cardiac catheterization, respectively, and compared the correlation of them. Results The preoperative pulmonary artery systolic pressure were measured by continuous Doppler ultrasound and cardiac catheterization were（45.89 ± 15.04） mmHg and（46.70± 18.84） mmHg, respectively. The postoperative pulmonary artery systolic pressure were measured by continuous Doppler ultrasound and cardiac catheterization were （35.17 ±11.08 ）mmHg and （33.09 ± 13.74） mmHg, respectively. There were no statistical difference （ preoperation, t = 0. 43, P 〉 0.05 ; postoperation, t = 1.54 P 〉 0.05 ）. The pulmonary artery systolic pressure were measured by continuous Doppler ultrasound and cardiac catheterization were positive correlation （ preoperation, r = 0. 748, P 〈 0.01 ; postoperation, r = 0. 795, P 〈 0.01 ）. Conclusion Continuous Doppler echocardiography can accurately assess pulmonary artery systolic pressure in patients with congenital heart disease combined pulmonary hypertension, and it has important clinical application value.
