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 ESRD and 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.
