Key high-yield points
- AVSD (atrioventricular canal/endocardial cushion defect) - deficiency at the crux of the heart: primum ASD + inlet VSD + common AV valve
- Most common cardiac defect in Down syndrome (trisomy 21) - ~40-45% of those with congenital heart disease; not ASD or VSD alone (though both are also more prevalent in Down syndrome)
In any child with trisomy 21 and signs of cardiac disease, AVSD should be the first diagnosis to consider - not isolated ASD or VSD.
