Siamese twins: killing one to save the other
pubmed.ncbi.nlm.nih.gov
The birth of Siamese twins joined at the chest (thoracopagus twins) and sharing a heart creates an ethical dilemma. Infants with conjoined hearts survive no more than a few months, and physicians must decide whether to give one child a chance at life by separating the twins and sacrificing one to give the other an intact heart.
Nevertheless, Annas concludes that the bleakness of the twins' prognosis if they remain joined justifies separation and the death of one child, despite the difficulty of developing a rationale for the act.
