Distribution of CHD types among DS patients. Proportion of DS patients with a given CHD grouped according to [15, 8]: complex defects (AVSD, aortic arch abnormalities, tetralogy of Fallot, transposition of the great arteries, and single ventricle hearts), valve defects (aortic, pulmonary, and mitral-tricuspid valve defects), shunt defects (isolated VSD, isolated ASD, and isolated patent ductus arteriosus), and other defects [15]. do not report prevalence rates for the latter three groups according to year of birth, so for this study only proportions of complex defects are displayed in the figure. CHD: congenital heart defect. DS: Down syndrome. AVSD: atrioventricular septal defect. VSD: ventricular septal defect. ASD: atrial septal defect
