Abstract:
Determination of the right ventricular outflow tract velocity time integral (RVOT VTI) is an important part of the noninvasive investigation of pulmonary blood flow in adults; however, age-related pediatric reference data are lacking. We examined growth-related changes of RVOT VTI values in children and the predictive value of RVOT VTI values in identifying enhanced pulmonary blood flow in children with secundum type atrial septal defect (ASD). A prospective study was conducted in a group of 570 healthy children and 52 children with a moderate-sized to large ASD. We determined the effects of age, body length (BL), body weight (BW), and body surface area (BSA) on RVOT VTI values. The predictive value of normal values stratified for age, BW, BL, and BSA was tested in our 52 ASD children. RVOT VTI values ranged from mean 9.7 ± 1.2 cm in neonates to 23.3 ± 2.7 cm in children with 18 years of age and showed a positive correlation with age, BL, BSA, and BW. In our population, RVOT VTI z-scores showed a high specificity for detecting ASD patients (>97 %) with sensitivity up to 71 %. We provide normal ranges and calculated z-scores of pediatric RVOT VTI values. Normal RVOT VTI z-scores might be additional predictors in identifying increased pulmonary blood flow in patients with ASD.
