应用彩色多谱勒超声心动图监测心脏移植术后排斥反应

目的 评价超声心动图在监测心脏移植术后急性排斥反应中的作用。方法 采用Accuson型彩色多谱勒超声心动图诊断仪,应用M型超声观察室壁厚度及活动度、有无心包积液;应用B型超声观察各房室腔大小;用脉冲多谱勒频谱测E峰峰值流速、A峰峰值流速及E/A值,连续观察120 d后行心内膜心肌活检（EMB）。结果 超声心动图连续监测4个半月未发现排斥反应征象,心脏结构、功能正常。结论 动态应用超声心动图监测心脏移植后早期急性排斥反应的发生具有安全、迅速、无创、无并发症的优点,同EMB相比有明显优越性。

Monitoring of acute rejection by Doppler echocardiography after heart transplantation

Objective This study aimed to assess the value of echocardiography (ECG) in monitoring acute rejection episode after heart transplantation. Method M-ECG was used to measure the thickness of the ventricular wall and to detect pericardial effusion. The arterial and ventricular volume was mesured by B-ECG. Doppler-ECG was used to measure ventricular peak flow velocity in early diastolie (E: PFVE) and peak flow velocity in late diastolie (A: PFVA) of the mitral valve and tricuspid valve, and E/A ratio. Conclusion Consecutive ECG examination is rapid, safe, noninvasive and free of complication in detecting graft rejection, and has obvious advantages over endomyocardial biopsy (EMB).
