RISK FACTORS OF CONGENITAL HEART DISEASE
FETAL
---Chromosomal abnormalities
---extracardiac anatomic abnormalities ( nonimmune hydrops ,single umblical artery ,renal agenisis omphalocoele etc)
---fetal cardiac arrhythmia
---suspected cardiac anomaly on routine usg
---thickened nuchal translucency(>/-3.5mm)
---monochorionic plancentation
MATERNAL
----Family history of CHD
----maternal metabolic disorder ( diabetes ,PKU)
---maternal teratogen exposure (lthium,hydantoin,valproic acid ,ethanol,isotretinoin,ACE inhibitors ,SSRIs)
---pregnancy of assisted reproduction
---maternal obesity
