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。
Objective To evaluate the value of color Doppler echocardiography in the assessment of pulmonary artery systolic blood pressure in patients with congenital heart disease complicated pulmonary hypertension by continuous Doppler regurgitation pressure drop [1]. Methods Sixty patients with left-to-right shunt congenital heart disease complicated with pulmonary hypertension and tricuspid regurgitation were evaluated with pulmonary artery pressure / systemic pressure ratio before surgery and with pulmonary artery pressure / Systemic pressure ratio comparison. Results Doppler echocardiography was used to estimate the ratio of pulmonary arterial pressure to systemic pressure and was highly correlated with the ratio of pulmonary arterial pressure to systemic pressure during operation (r = 0.82, P <0.01). Conclusion The results show that the Doppler echocardiography manometry can provide reliable maximum tricuspid valve pressure, which can provide valuable hemodynamic data for the clinical drug treatment and disease analysis of patients, which can be used for qualitative and quantitative analysis of pulmonary hypertension Quantitative diagnosis, this method can provide surgical timing of surgery, and predict the feasibility of surgery.
