One of the first questions people ask after learning they may need a heart transplant is:
“How long am I going to have to wait?”
It is a completely understandable question. When you are living with advanced heart failure,
waiting for a transplant can feel like your entire life is on hold. You may wonder whether
you will wait weeks, months, or even longer.
The truth is that there is no single answer for how long someone will wait for a
heart transplant.
Some people receive a donor heart relatively quickly. Others may wait much longer. The
amount of time depends on many factors, including your medical urgency, blood type, body
size, where the donor heart becomes available, and whether a suitable heart is available.
The Heart Transplant Waiting List Is Not a Simple Line
One of the biggest misconceptions about transplantation is that being listed means you
receive a number and simply wait your turn.
That is not really how heart transplantation works.
When a donor heart becomes available, the transplant system considers potential recipients
using allocation policies designed to match the heart with an appropriate candidate.
For adult heart candidates, factors include medical urgency, blood type matching,
and distance between the donor hospital and transplant hospital.
Waiting time can also matter. When candidates otherwise have the same priority, the person
who has been waiting longer may receive priority.
This means that the person who has been on the waiting list the longest does not necessarily
receive the next available heart.
Every donor heart is different, and every patient is different. The system has to determine
which candidate is an appropriate recipient for that particular heart.
So, How Long Do People Actually Wait?
There is no reliable number of days or months that applies to everyone.
Historical OPTN monitoring data showed that the overall median time spent waiting before an
adult heart transplant fell from 263 days to 69 days after the heart
allocation system was changed in October 2018. However, that statistic describes a population
over a particular period of time. It is not a prediction of how long an individual
patient will wait.
Wait times can also vary significantly by geographic area and by a patient’s medical status.
In the five-year monitoring report, median waiting times varied considerably among OPTN
regions in the post-policy era.
The most important thing to remember is this:
A median wait time is not a promise.
Your own wait could be shorter or longer.
Why Does Blood Type Matter?
Blood type can affect how quickly a suitable donor heart becomes available.
A donor heart must meet specific blood-type matching requirements under the current heart
allocation policy. Because different blood types occur at different frequencies in the
population, the pool of potentially compatible donor hearts can vary from patient to patient.
Blood type is only one part of the equation, however.
The donor heart also needs to be medically suitable and appropriately matched to the
recipient. Size and other medical considerations can affect whether a particular heart is
appropriate.
Your Medical Status Matters
Your medical condition can change while you are waiting.
Adult heart transplant candidates are assigned one of six medical urgency statuses, with
Status 1 being the most urgent and Status 6 the least urgent. Your status
is based on specific medical criteria and can change as your health or treatment changes.
Patients receiving advanced support such as certain forms of mechanical circulatory support
may qualify for a higher urgency status depending on their circumstances.
This is one reason the waiting process can change quickly.
You might spend months preparing for a transplant and then suddenly receive a call because
your medical circumstances or the availability of an appropriate donor heart has changed.
An LVAD Can Change the Waiting Experience
For some people with advanced heart failure, an LVAD can be used as a bridge to transplant.
An LVAD, or left ventricular assist device, is a mechanical pump that helps circulate blood
when the heart cannot pump effectively. Some patients are able to leave the hospital and
live at home with an LVAD while waiting for a transplant.

What Is an LVAD?
Having an LVAD does not mean a patient is guaranteed to receive a heart quickly. It can,
however, provide mechanical support while the patient continues to wait and be monitored.
I know this part personally.
My own heart transplant journey included an LVAD. When I was first listed, I was listed at
Status 4 while stable with my LVAD. Later, after a right-heart catheterization showed
pressures my doctors were concerned about, my status was changed to Status 2.
About 45 days later, I received the call that a donor heart had been found.

My Heart Transplant.
That experience taught me something important:
You can spend a long time preparing for a transplant, and then everything can
change with one phone call.
The Waiting Can Be an Emotional Roller Coaster
The physical side of waiting is only part of the experience.
There is also the emotional side.
You may wake up every morning wondering if today will be the day.
You may keep your phone beside you constantly.
You may hesitate to make plans because you don’t know when the call will come.
And when someone else receives a transplant, you may feel genuinely happy for them while
also wondering:
“When will it be my turn?”
Those feelings are normal.
Waiting for a transplant can be incredibly difficult, especially when you understand that
another person’s tragedy is what makes your second chance possible.
Even When You Get the Call, It Isn’t Always Certain
One thing that surprised me about my own transplant experience was that receiving the phone
call did not mean the transplant was guaranteed.
When a potential donor heart is identified, additional testing and evaluation still have to
take place. The transplant team needs to determine whether the heart is appropriate and
whether everything can move forward.
Sometimes a potential transplant is cancelled. Patients often call this a
“dry run.”
That can be emotionally difficult because you have already started imagining your life after
transplant.
In my case, the process involved a lot of “hurry up and wait.” The heart had been identified,
but doctors still had to complete testing and make sure it was going to be a suitable match.

My Heart Transplant.
Why Can’t a Donor Heart Simply Be Stored?
A donor heart has a very limited preservation window.
Hearts and lungs have among the shortest preservation times of transplanted organs and are
generally transplanted within about six hours after recovery, although transplant teams make
decisions based on the individual circumstances.
This is one reason the transplant process can suddenly become a race against the clock.
The donor hospital, organ procurement organization, transplant surgeons, transportation
teams, laboratories, and recipient’s transplant hospital may all be coordinating at the
same time.

How Are Donated Organs Transported?
There Are Thousands of People Waiting
The need for donor hearts remains significant.
In 2024, 9,444 people were on the U.S. heart transplant waiting list,
according to the Scientific Registry of Transplant Recipients’ 2024 Annual Data Report.
At the same time, thousands of heart transplants are performed each year.
Every donor heart represents an opportunity for someone who may have been waiting for months
or years for a second chance.
And behind every donated heart is a donor and donor family who made an extraordinary gift
during an incredibly difficult time.
What Can You Do While You’re Waiting?
If you’re waiting for a heart transplant, there are things you can control even though you
cannot control when a donor heart becomes available.
- Stay in close contact with your transplant team.
- Take your medications exactly as prescribed.
- Tell your transplant team about significant changes in your health.
- Keep your phone number and contact information up to date.
- Follow your transplant team’s instructions about diet, activity, testing, and appointments.
- Keep your phone nearby in case your transplant center calls.
Your transplant center can also tell you what you should do if you develop symptoms or become
too sick to remain at home.
Don’t Compare Your Wait to Someone Else’s
This may be one of the most important things to remember.
If someone you know waited two months and you have already been waiting six months, that does
not necessarily mean something is wrong.
Another patient may have a different blood type, different body size, different medical
urgency, different geographic circumstances, or a different donor opportunity.
Your transplant team knows your individual situation better than any statistic on the
internet ever could.
Ask them questions.
Ask where you currently stand. Ask what your medical status means. Ask whether anything has
changed that could affect your transplant eligibility or urgency.
And don’t be afraid to ask the same question more than once.
The Waiting Is Hard—But You Are Not Just Waiting
When you’re on the heart transplant list, it can feel like you’re simply sitting around
waiting for someone to call.
But that’s not really what is happening.
Your transplant team is monitoring you, managing your health, adjusting treatment when
necessary, and trying to keep you in the best possible condition for transplant.
The goal isn’t simply to wait.
The goal is to stay as healthy as possible until the right heart becomes available.
I know from personal experience that the waiting can be frightening, frustrating, and
exhausting.
But I also know what can happen when that phone finally rings.
For me, that call came on August 30, 2019.
My life changed that day.
And I will always be grateful to the donor and donor family who made that second chance
possible.
Frequently Asked Questions About Heart Transplant Wait Times
How long is the average wait for a heart transplant?
There is no single average wait time that accurately predicts what an individual patient
will experience. Historical national data have shown substantial variation, and wait times
depend on medical urgency, blood type, donor availability, geography, and other factors.
Is the heart transplant waiting list first come, first served?
No. Heart allocation is not simply a first-come, first-served line. Medical urgency,
blood-type compatibility, geographic distance, and other allocation criteria are considered.
Waiting time can help determine priority when candidates otherwise have the same priority.
Does blood type affect heart transplant wait time?
Yes. Blood type is one of the factors used when matching donor hearts with transplant
candidates. Because blood types are not equally common, blood type can influence the pool
of potentially compatible donor hearts.
Does having an LVAD affect the heart transplant wait?
An LVAD may be used as a bridge to transplant for some patients with advanced heart
failure. Depending on the patient’s medical circumstances and the type of support required,
mechanical circulatory support can affect transplant urgency status.
Can your heart transplant status change while you wait?
Yes. A patient’s medical condition and treatment can change, and their transplant status
may change accordingly. Your transplant team determines your status based on the applicable
medical criteria.
What happens when a donor heart becomes available?
The transplant center contacts the potential recipient and begins the final evaluation
process. The donor heart is evaluated and transported while the recipient prepares for
surgery. A potential transplant can still be cancelled if testing shows that the heart is
not appropriate.
Can a heart transplant be cancelled after you receive the call?
Yes. A preliminary donor-heart offer is not always a guarantee that transplantation will
occur. Additional testing and evaluation may reveal that the heart is not suitable.
Patients sometimes refer to this as a “dry run.”
A Final Word
If you or someone you love is waiting for a heart transplant, talk with your transplant team
about your individual situation.
There is no universal waiting time, and statistics cannot predict exactly when a particular
patient will receive a donor heart.
The waiting can be one of the hardest parts of the transplant journey. Try to focus on what
you can control: following your treatment plan, staying in contact with your transplant team,
taking care of yourself, and being ready when the call comes.
Keep fighting. Keep asking questions. Keep hope alive.
