In brief: Cardiac defects

Depends on how you want to start? The most lethal would be if the defects (such as anencephaly or hypoplastic left heart syndrome) cause stillbirth (late fetal death) or infant death or pregnancies are terminated after the prenatal diagnosis of fetal defects in more than 50% of cases.
