Donation After Cardiac Death

Overview

Not every donation after death happens after brain death. When a patient cannot recover but does not meet the rules for brain death, donation can still happen after the heart stops. This path is called donation after cardiac death, or DCD. It starts with a family decision to withdraw life support. Donation follows once the heart has stopped on its own.

DCD has grown a lot over the past two decades. New ways of caring for donor organs keep them healthy enough to use, even after the heart stops. Many families find this path gives them a way to honor a loved one when no other care can help.

What is donation after cardiac death?

Not all donations happen after brain death. When someone's heart stops and physicians determine it cannot be restarted, families can choose to allow organ donation. This process, called donation after cardiac death (DCD), is becoming more common and offers another path to give the gift of life.

Key aspects of donation after cardiac death:

• Different from brain death. The heart itself has failed, not the brain
• Controlled process. Life support is withdrawn in a planned, organized way
• Time-sensitive. Organs must be recovered quickly after death is declared
• Growing option. More hospitals now offer DCD as families want more donation choices
• Helps waiting list. Expands the donor pool for patients on transplant waiting lists

What is donation after cardiac death?

Donation after cardiac death (DCD) means the person's heart has stopped beating and cannot be restarted. Unlike brain death, where the brain is dead but the heart still pumps with machine support, in DCD the heart itself has failed. The heart cannot be revived no matter what treatment is attempted.

When cardiac death occurs

Cardiac death happens in several situations:

• Massive heart attack. The heart muscle is too damaged to recover
• Chest injuries. Trauma that prevents the heart from functioning
• End-stage heart failure. All treatment options have been exhausted; recovery is not possible
• Heart failure in other conditions. The brain may still function, but the heart will not work
• Medical determination. Physicians determine restarting the heart is not medically possible

If the family chooses donation, organs can still be recovered after cardiac death. Organs no longer receive oxygen-rich blood, creating a different donation path that serves patients on the waiting list.

How is this different?

The fundamental difference is in the sequence of events. In brain death donation, the brain is dead but the heart is still beating. In cardiac death donation, the heart has stopped but the brain may still be functioning.

Brain death donation process:

• Brain is dead (confirmed by testing)
• Heart continues beating with machine support
• Life support maintains organs for transplant
• Death is declared based on neurological criteria
• Donation happens while life support is ongoing

In DCD, the sequence is different and requires a different type of decision. The family chooses to stop life support and allow natural death. Once the heart stops and death is declared by a physician, donation becomes possible.

The brain may still be functioning when this decision is made, which differs from brain death cases where the brain has already been declared dead.

How the process works

Families considering DCD need to understand the full sequence of what will happen and when. This process is very different from brain death donation because it begins with a decision about whether to continue life support. The medical team will be clear about what to expect.

Withdrawal of life support

When medical treatment is no longer helping the person recover and the prognosis is poor, the family and medical team may discuss withdrawing the ventilator or stopping medications that are not extending meaningful life. This happens whether or not donation is being considered. If the family is interested in donation, this conversation includes specific information about the donation process:

• The person will be moved to an operating room
• Life support will be withdrawn
• When the heart stops, death will be declared
• Organ recovery will happen immediately after

Families understand that stopping life support will lead to death regardless of donation. The timeline doesn't change significantly—donation doesn't prolong dying.

The waiting period

After consent for donation is obtained, there's often a waiting period. This wait allows time to find recipients and prepare the surgical team.

The person remains on life support during this time. For families, this waiting can feel anxious, but the medical team keeps you informed about progress.

Which organs can be donated?

After cardiac death, organs may still be viable depending on the person's health and how quickly circulation is restored. Advances in preservation technology have expanded which organs can be recovered from DCD donors.

Organs that may be recovered from DCD donors include:

• Kidneys. Most commonly recovered; can function well even with some warm ischemia time
• Liver. May be recovered, especially with newer preservation techniques like EVHP
• Heart. Increasingly recovered from DCD donors using advanced perfusion and resuscitation techniques to assess and preserve heart function for transplantation.
• Lung. Increasingly recovered from DCD donors using ex vivo lung perfusion (EVLP) to assess and recondition them
• Pancreas. Can sometimes be used for transplant; timing is more critical

Tissues may also be recovered—corneas, skin, bone, and connective tissue. Tissue recovery doesn't require the same timing as organs, so tissues can be recovered even if organs aren't viable.

The medical team evaluates which organs are suitable based on the person's condition and medical history. Timing is critical in DCD because organs must be recovered quickly once the heart stops.

Unlike brain death donation where organs receive oxygen-rich blood continuously, DCD organs lose that blood supply immediately when the heart stops. This limits how long they remain viable for transplant.

Questions families ask

Families often have specific concerns about the donation process after cardiac death:

• "Does my family have to be there?" Some families want to be present; others prefer to say goodbye beforehand. Both are valid choices that medical teams accommodate.

• "Is this the same as letting them die?" If life support cannot help recovery, withdrawing it allows natural death. Donation happens after that death. Death is coming regardless—donation gives your loved one's passing a final purpose.

• "How long will organs be usable?" DCD organs have a narrow window. Once the heart stops, organs have limited time before lack of oxygen causes damage. The surgical team works rapidly, usually within 30 minutes.

• "Does organ recovery happen immediately?" Physicians wait a few minutes to confirm no spontaneous heartbeat. Then organ recovery begins in the operating room within an hour.

• "What if the heart doesn't stop quickly?" Occasionally the heart continues beating longer than expected. After an agreed-upon period, if the heart hasn't stopped, natural death occurs and donation may proceed as tissue donation only or may not happen. Families are informed of this possibility beforehand.
