[Echocardiographic diagnosis of acute rejection of transplanted heart].
Comparing echocardiographic parameters with endomyocardial biopsy findings in 6 patients with acute crises of mild, moderate, and severe graft rejections and in 2 patients with persistent acute rejection crisis has shown that there are decreases in end-diastolic size and left ventricular end-diastolic ejection fraction volume, an increase in left ventricular myocardial mass, and thickening of the left ventricular posterior wall and ventricular septum, as evidenced by ultrasonic study. Such changes are detected in moderate and severe acute crises of graft rejection. Normalization of ultrasonic parameters of the grafted heart occurs 2-3 weeks after abolition of rejection crisis. A positive dynamics of echocardiographic parameters in persistent acute rejection crises suggests a good prognosis. Echocardiographic monitoring data obtained in the outpatient setting may serve an indication for unplanned endomyocardial biopsy.
