- W1964739969 abstract "Ventricular septal defect (VSD) is an opening in the interventricular septum. 30-50% of patients with congenital heart disease have VSD.The aim of the study was to determine the dependence of the left ventricular diastolic dimension (LVD), left ventricular systolic dimension (LVS), shortening fraction (SF), left atrium (LA), pulmonary artery truncus (TPA) on the body surface and compare their values among experimental, control and a group of healthy children. Values of maximal systolic gradient pressure (Pvsd) of VSD were compared with children from one experimental and control group.Children were divided into three groups: experimental (32 children with VSD that were to go to surgery), control (20 children with VSD who did not require surgery) and 40 healthy children. Measurements of LVD, LVS, SF, LA, TPA were performed in accordance to recommendations of the American Echocardiographic Association. The value of Pvsd was calculated from the maximal flow velocity (V) in VSD using the following formula: Pvsd = 4 x V2 (mm Hg).For children from the experimental group, the relationship between the body surface and the variability of the LVD was explained with 56.85%, LVS with 66.15%, SF with 4.9%, TPA with 58.92%. For children from the control group, the relationship between the body surface and the variability of LVD was explained with 88.8%, LVS with 72.5%, SF with 0.42%, PA with 58.92%. For healthy children, the relationship between the body surface and the variabilitiy of the LVD was explained with 88.8%, LVS with 88.78%, SF with 5.25% and PA with 84.75%. There was a significant statistical difference between average values of Pvsd in the experimental and control group (p < 0.02).The presence of the large VSD has an influence on the enlargement of LVD, LVS, SF,TPA. The enlargment of the size of the pulmonary artery depends on the presence of VSD and there is a direct variation in the magnitude of the shunt. There is a relationship and significant dependence of the LVS and LVD on the body surface. There is no statistically significant dependence between SF and body surface." @default.
