Abstract
Background:
Cardiac dysfunction is a risk factor for death in patients with sickle cell disease (SCD).
Aim of the Work:
Aim of the work is to evaluate the right ventricular systolic and diastolic functions by tissue Doppler and speckling tracking imaging in children with SCD.
Subjects and Methods:
Thirty children with SCD and thirty controls were subjected to clinical, laboratory evaluations, and echocardiographic study using GE Vivid 7 (GE Medical System, Horten, Norway with a 3.5-MHz multifrequency transducer) including; Two-dimensional and tissue Doppler echocardiographic study (lateral tricuspid valve annulus peak E’ velocity, lateral tricuspid valve annulus peak A’ velocity, E’/A’ ratio, isovolumetric relaxation time, lateral tricuspid valve annulus S’ and septal S’ waves and peak longitudinal systolic strain [PLSS] and time to PLSS) were done in six right ventricular segments.
Results:
There was a significant decrease in right ventricular systolic and diastolic function in patients group when compared to controls.
Conclusions:
Children with SCD have impaired right ventricular systolic and diastolic functions when compared to healthy children with early evaluation of the systolic dysfunction by speckle tracking imaging technique.
