Aim: To evaluate left ventricular (LV) diastolic function in children with end-stage renal disease (ESRD) using conventional pulsed-Doppler echocardiography and Doppler tissue imaging (DTI), and to compare the findings with these two modalities. Methods: Twenty-four children with ESRD and 22 healthy age-and sex-matched control subjects were assessed with conventional Doppler echocardiography and DTI. The scans of the renal disease patients were done after a dialysis session. Parameters related to LV systolic and diastolic function were compared in the ESRDand control groups. Results: The ESRD patients had lower mean mitral E/A ratio both according to conventional Doppler echocardiography and TDI than the control subjects. The ESRD group also had significantly longer isovolumetric relaxation time (116 ±31 ms vs 97 ±3.1 ms, respectively; p < 0.001), and significantly longer deceleration time (235 ±44 ms vs 202 ±35 ms, respectively; p < 0.01) than the control group. Conclusion: DTI findings correlate well with conventional Doppler echocardiography findings. Children with ESRD show, after dialysis, echocardiographic signs of LV diastolic dysfunction.
