Abstract

Detection of acute cardiac allograft rejection (AR) remains an important clinical challenge. The role of Doppler echocardiography for the non-invasive diagnosis of AR is controversial, in particular with regard to milder forms of rejection. This study was designed to evaluate the potential of Doppler echocardiography for the non-invasive diagnosis of mild AR. Serial measurements of left and right ventricular filling parameters were performed in 31 heart transplant recipients and compared with simultaneously obtained endomyocardial biopsies. To account for biological and technical variability, consecutive rejection-free studies were used to calculate 95% confidence limits for mitral and tricuspid maximum early flow velocity and pressure half time. Measurements obtained during mild AR were then compared to these data. The study demonstrated that all parameters varied considerably between consecutive rejection-free examinations. Changes in left and right ventricular filling parameters during mild AR rarely exceeded the calculated 95% confidence limits. Thus Doppler echocardiography appears of little value for the non-invasive diagnosis of mild acute cardiac rejection.
