目的：研究组织多普勒技术对单纯先天性心脏病患者肺动脉压力及其分级的判断价值。方法选择2012年2月至2013年3月我院收治的先天性心脏病患者140例，按治疗先后顺序分为观察组和对照组各70例。对照组使用心导管术测量其肺动脉压力。观察组患者应用组织多普勒技术测量肺动脉血流频谱的时间间期参数、瓣膜返流速度和心内分流速度，估测患者肺动脉压力。观察对比两组患者的血流动力学参数，并观察记录两组患者肺动脉高压的分级情况。结果观察组患者右心房平均压、平均肺动脉压和肺动脉收缩压等血流动力学参数均显著高于对照组患者，差异具有统计学意义(P<0.05)；观察组中肺动脉高压患者所占比例为100.00%，高于对照组的85.71%，但差异无统计学意义(P>0.05)。结论组织多普勒技术在对单纯先天性心脏病患者肺动脉压力及其分级的判断上有很良好的使用价值，值得推广。

Objective To study the value of tissue Doppler imaging in pulmonary arterial pressure and its classification of patients with simple congenital heart disease (CHD). Methods 140 CHD patients treated in our hospital from February 2012 to March 2013 were selected and divided into observation group and control group according to treatment order, with 70 cases in each group. The control group was given cardiac catheterization to measure the pulmonary arterial pressure, the observation group was given tissue Doppler imaging to measure the time period parameter of blood spectrum, speed of valvular regurgitation and intracardiac shunt, so as to measure patients' pulmonary arterial pressure. The hemodynamic parameters and classification of pulmonary arterial hypertension between two groups were observed and recorded. Results The hemodynamic parameters (including RAMP, MPAP and PASP) of observation group were significantly higher than those of control group, with statistical difference (P <0.05); the proportion of pulmonary arterial hypertension in observation group was 100.00%, higher than 85.71% in control group, but the difference was not statistical (P >0.05). Conclusions Tissue Doppler technology has good value in pulmonary artery pressure and its classification of patients with simple congenital heart disease, which is worthy of promotion.
