Question 1

Answer 1

Ebstein anomaly of tricuspid valve (displacement of tricuspid valve toward apex of right ventricle => atrialization of RV segment), associated with maternal lithium use

Question 2

Eggs on a string heart

Answer 2

dextro-transposition of great arteries (anterior-posterior relationship of great arteries result in narrow mediastinum or “string”)

Answer 3

Tetrology of Fallot

Question 4

Metaphyseal fraying and cupping, widening of epiphyses in distal radius and ulnar (dz)
