SUMMARY Gimenez S, Teixeira ML, Myashiro R, Carmona MJC, Auler Jr JOC,Malbouisson LMS – Computed Tomography in Pulmonary Evaluationof Children with Acyanotic Congenital Heart Defect and PulmonaryHyperflow. BACKGROUND AND OBJECTIVES: Respiratory dysfunction is commonin children with acyanotic congenital heart defects (ACHD) withpulmonary hyperflow; however, little is known about the pulmonarystructure of those patients. The objective of this study was to quantifythe volumes of air and tissue, as well as the distribution of pulmonaryaeration in this population. METHODS: After approval by the Ethics Committee of the institutionand signing of an informed consent, seven children with ACHD withpulmonary hyperflow underwent computed tomographies of the chest.All images included the left and right pulmonary contour, andpulmonary volumes and weight were calculated using volumetric data.Paired Student t test was used to compare left and right, andexponential regression was used for correlations.
