Do all Down syndrome babies have heart defects?
Approximately half of all infants born with Down syndrome have a heart defect. Many of these defects have serious implications and it is important to understand them and how they may affect the child so that appropriate medical treatment may be provided.
What is the most common cardiac anomaly in Down syndrome?
In conclusion, patent ductus arteriosus is the commonest congenital cardiac anomaly in children born with Down syndrome at our institution.
What are 4 common congenital anomalies of a child with Down syndrome?

The other most common anomalies associated with cases with DS were syndactyly, club foot, polydactyly, limb reduction, cataract, hydrocephaly, cleft palate, hypospadias and diaphragmatic hernia.
What is the most common heart defect in trisomy 21?
Aim: Atrioventricular septal defect (AVSD) is widely accepted as the most common type of congenital heart defect in trisomy 21.
Which is more common ASD or VSD?
Congenital heart defects affect slightly less than 1% of liveborn infants. Two defects, ventricular septal defect (VSD) and atrial septal defect (ASD), account for about 30% of congenital heart disease: VSD for 20% and ASD for 10%.
