Developmental delay associated with normal thyroidal function and long-term amiodarone therapy during fetal and neonatal life.

We reported a case of a child with neurodevelopment delay induced by long-term amiodarone exposure due to a treatment of fetal supraventricular tachycardia (FSVT), subtype permanent junctional reciprocating tachycardia (PJRT) with the normal thyroidal function. Refractory persistent FSVT was treated intrautero with digoxin (0.5 mg QD) until delivery and amiodarone (100 mg QD) from 26 to 35 weeks of gestation.
