EXOD462 A published responsum dealing specifically with heart transplants is that of Rabbi Unterman [Unterman, I.Y., "Points of Halakhah in the Question of Heart Transplantation" (From an address to the Congress of Oral Law), Jerusalem, Elul, 5728 (August, 1968)] who begins by stating that consent from the family of the donor must be obtained. Otherwise, the doctors and the recipient would transgress the prohibition of "Thou shall not steal" [this verse and Deut. 5:17]. The Chief Rabbi then reviews the halakhic definition of death. He states that under ordinary circumstances, death occurs when respiration ceases. However, sudden unexplained death in young otherwise healthy individuals should be followed by resuscitative measures. A goses need not be resuscitated when respiration ceases. Rabbi Unterman then briefly mentions the problem of organ banks by stating that freezing organs for later use is allowed provided there is a good chance they will be used to save a life. Then, the situation would be comparable to having the recipient at hand (lefaneinu).
