Abstract
OBJECTIVE: This study aimed to evaluate biventricular function, brain natriuretic peptide levels, respiratory function test and 6 minute walking test (6MWT) in children with repaired tetralogy of Fallot (TOF), and analyse the correlation between these variables and clinical status. METHODS: Twenty-five children (14 boys, 11 girls; aged 6 to 17 years) with repaired TOF (Group 1) and 25 age-sex matched healthy controls (Group 2) were enrolled in the study. Tissue Doppler echocardiography, respiratory function test, 6MWT distance and brain natriuretic peptide levels were measured. RESULTS: Mean ages of the children at TOF corrective surgery and at study time were 5.1+-3.5 years and 11.6+-2.7 years respectively. The duration between palliative operation and corrective surgery was 4.3+-2.0 years, and the follow-up period after corrective surgery was 6.3+-3.0 years. The right ventricular and left ventricular myocardial performance indices (MPIs), and isovolumic relaxation and contraction times were significantly higher in Group 1 than in Group 2 (p
