| 摘 要： | 目的 探讨组织速度多普勒成像(TVI)技术评价缺氧性肺动脉高压(HPH)新生儿右心室功能的价值.方法 35例HPH患儿及28例正常新生儿于生后3 d应用超声心动图测量肺动脉收缩压(PASP),用传统超声技术测定右室射血分数(RVEF)值、右心室舒张早期峰值(E峰)、舒张晚期峰值(A峰)、E/A值,同时以TVI技术测量三尖瓣环指标(收缩期波Sa、舒张早期波Ea、舒张晚期波Aa、Ea/Aa值).结果 HPH组三尖瓣环Sa、Ea、Ea/Aa及RVEF值较对照组减低(t=2.67～4.69,P均<0.01).HPH组的右心室E/A值较对照组减低,但差异无统计学意义.HPH组的三尖瓣环Sa与RVEF值呈正相关(r=0.451,P<0.05).结论 HPH新生儿的右心室舒张、收缩功能减低,TVI技术与传统超声技术结合能更敏感地发现右心室功能变化.

| Abstract: | Objective To investigate the roles of tissue velocity Doppler imaging(TVI)technology in assessing right ventricular function in neonates with hypoxia-induced pulmonary hypertension(HPH).Methods Thirty-five(35)three-day-old neonates of HPH group and 28 healthy neonates of control group were performed echocardiographic examinations to measure the pulmonary artery systolic pressure(PASP),and conventional ultrasound technology to get their right ventricular ejection fraction(RVEF),early diastolic peak(peak E),l... |
