Assessment of diastolic function in children and adolescents with beta-thalassemia major by tissue Doppler imaging

Aim: The purpose of this study was to analyze myocardial diastolic function in patients with beta-thalassemia major before development of overt cardiomyopathy using pulsed wave tissue Doppler imaging, and compare data with conventional Doppler echocardiography. Material and Method: The study included 61 beta-thalassemia major subjects (age 4 to 20 years; mean age, 10.7±4.1 years; 32 females and 29 males) with normal left ventricular function and 52 healthy control subjects, matched for age and sex. All participants underwent M-mode echocardiography and left ventricular systolic function was measured; diastolic functions of the right and left ventricul were analysed using issue Doppler imaging and conventional Doppler echocardiography. SPSS for Windows 13.0 software programme was used for statistical analysis, and the student’s t-test was used to compare data. This study was approved by the ethics committee of the ‹stanbul Medical Faculty. Results: Body surface area was significantly smaller in the patients than in the controls (1.0±0.2 vs. 1.2±0.3 m2, p
