A bullet entered the cranial vault of a boy and migrated via the transverse venous sinus to the opposite side of the skull and thence via the great veins to the right ventricle. Emergency craniotomy arrested hemorrhage, and 19 days later, the bullet was retrieved by open cardiotomy. Its location astride the left anterior descending coronary artery illustrates that removal of an apparently trivial foreign body from the heart is occasionally justified.
