Abstract

Aims: Although there are plenty of data about the differences in left ventricular tissue Doppler (TD) velocities by preload reduction, only a few studies regarding right ventricular function are found in the literature. We investigated the effect of intravascular volume reduction on right ventricular function by ultrafiltration in dialysis patients. Methods: 27 end-stage renal failure patients who were hypervolemic and undergoing hemodialysis were included in the study. TD studies of the right ventricle were performed before and 1 h after dialysis. These data were compared. Results: The mean age of the patients was 41 ± 15 years and mean volume of ultrafiltration was 3.8 ± 1.8 liters. Systolic, early and late diastolic lateral annular TD velocities before dialysis were 0.109 ± 0.029, 0.088 ± 0.039, 0.111 ± 0.039 m/s, and after dialysis were 0.099 ± 0.028, 0.078 ± 0.036, 0.106 ± 0.037 m/s, respectively (p = 0.216, p = 0.112, p = 0.350). Myocardial early diastolic velocity decreased significantly (p = 0.049) but systolic and late diastolic velocities did not change significantly (p = 0.579, p = 0.146). Conclusion: Right ventricular systolic and diastolic velocities detected by TD were not or only minimally affected by preload reduction in hemodialysis patients and the TD early/late ratio is the most valuable variable that can predict right ventricular diastolic function. The right ventricular systolic and early diastolic TD velocities were positively correlated with left ventricle ejection fraction.
