【摘要】 目的 利用彩色多普勒超声心动图检测在先天性心脏病合并肺动脉高压中根据连续多普勒三尖瓣反流压差估测肺动脉收缩压的价值[1]。方法 对60例左向右分流型先天性心脏病合并肺动脉高压,同时有三尖瓣反流的患者, 于术前用上述方法估测肺动脉压/体循环压的比值,与术中所测得肺动脉压/体循环压的比值比较。结果 多普勒超声心动图用上述方法估测肺动脉压/体循环压的比值,与术中所测得肺动脉压/体循环压的比值高度相关(r=0.82,P<0.01)。结论 结果表明,多普勒超声心动图测压法可提供可靠的最大三尖瓣跨瓣压,可为患者临床药物治疗及病情分析提供宝贵的血流动力学资料,可用于肺动脉高压的定性和定量诊断,本方法可为外科提供手术时机,并对手术的可行性做出预测。

【Abstract】 Objective To estimate the value of pulmonary arterial systolic pressure in terms of pressure difference in continuous-wave Doppler tricuspid regurgitation by using color doppler echocardiography in the treatment of inborn cardiac disease complicated with PAH (Pulmonary Artery Hypertension)[1]. Methods 60 cases of left-to-right shunt inborn cardiac disease complicated with PAH and tricuspid regurgitation were taken as examples ......
