It is possible in some countries to make a directed donation. The next-of-kin of the donor can, in the US, direct the relevant organ be used for a patient they know of. This is not permitted in many countries including India where the organ would go to the patient who is first on the waiting list. However, in order to donate your heart, you have to make sure that the manner of death does not damage the heart. This means that brain death has to happen without the heart stopping.
