ABOUT PH

Transplant

Lung transplantation can be a life-saving treatment option for some people living with pulmonary hypertension.

Transplant gave me back the ordinary things that once felt out of reach, like going up a flight of stairs without mapping out where I’d need to stop and breathe, being able to travel freely without measuring how many oxygen tanks I would need, and spending time with my family being present for moments I once feared I would miss.

Transplant cures pulmonary hypertension but comes with significant medical complexities of its own.

 

Double-lung transplant is the most common type of transplant for pulmonary hypertension patients. A single-lung transplant is less common than a double-lung transplant but may be appropriate for certain PH patients.

 

Heart-lung transplant is less common and used only when both the heart and lungs are badly damaged and the heart can’t recover on its own.

 

According to CIHI, in Canada in 2025, there were 51 single-lung transplants, 356 double-lung transplants, and 2 heart-lung transplants. Transplants for pulmonary hypertension are only a fraction of that total.

For many people living with pulmonary hypertension, lung transplant can feel overwhelming. When does it become an option? Who needs it? What does the process involve? Dr. John Granton, Director of the PH Program at Toronto General Hospital and Canadian Pulmonary Hypertension Medical Committee Programs Subcommittee Chair, walks us through the basics.

Does everyone with pulmonary hypertension need a transplant?

 

“No,” Dr. Granton explains. “We don’t really know the exact number.”

 

Modern PH therapies have significantly changed the timeline of disease progression, delaying—and sometimes preventing—the need for transplant. However, some patients still require transplant, especially those who do not respond to therapy or who have higher-risk forms of PH.

​

Not everyone who needs a transplant is eligible for one, and not everyone who is eligible chooses to have a transplant. Severe deconditioning (when someone loses physical strength through being ill, injured, or not active), high body mass index, smoking, substance use, or other medical conditions may make transplant too risky.

 

When is transplant discussed?

 

Dr. Granton believes transplant should be discussed earlier rather than later. Earlier conversations should occur (e.g. shortly after diagnosis) in some forms of PH that are less likely to respond to treatment. Conversations should also occur when patients either progress or fail to respond to maximal medical therapies.

 

Having the conversation does not necessarily mean immediate referral to the transplant assessment team, but it gives patients and families time to process the option and prepare.

 

It also allows time for people to:

  • Stop smoking

  • Address substance use

  • Lose weight

  • Improve their physical conditioning

  • Strengthen their support systems

​

“If you suddenly, in the final hour, start having that conversation, there’s no way they’re going to be able to lose weight or become conditioned,” he says.

 

How do patients react?
​

"It is going to be a difficult conversation for patients" he says candidly.

 

Some patients are shocked that their doctor is raising transplant as a possibility. Others are relieved to discuss it openly.

 

Avoiding the conversation, however, can be harmful. “I think you’re doing an injustice if you don’t have that conversation.”

 

What happens during transplant assessment?
​

The transplant assessment process is thorough — and can feel exhausting. Patients undergo scans, blood work, heart catheterization, and extensive evaluation, meeting:

  • A transplant physician and surgeon

  • Nurse coordinator

  • Social worker

  • Psychiatrist or psychologist

  • Physiotherapist

  • Nutritionist

  • Anesthesiologist

 

The social worker evaluates the patient’s support systems. Transplant isn’t the sort of thing you can go through without help. “It takes a village,” Dr. Granton says.

 

The physiotherapist assesses strength and prescribes exercise. Nutritionists prepare patients for steroid-related dietary changes.

 

The assessment timeline can range from a week (for critically ill patients) to several months. Once the patient has finished the evaluations, the transplant team meets to review their case.

 

Patients may be:

  • Added to the transplant waiting list

  • Conditionally listed (pending weight loss or other changes)

  • Deferred, if they do not need a transplant yet but may need one in future.

 

What happens if someone is approved?

 

If someone is listed, their priority for a transplant depends on their illness severity. The time to getting a transplant also depends on their blood type, body size, and antibody status.

 

The average wait time for a transplant is about six months, (again depending on urgency and other factors) though it varies widely.

 

What is life on the waiting list like?
​

Patients must stay ready to come to the hospital at any time. Their ability to travel is limited.

 

"People often feel like they're being held hostage, putting their lives on hold, for whatever time it takes,” Dr. Granton says.

 

At the same time, people are encouraged to stay active and improve their physical conditioning. “Prehabilitation” improves transplant outcomes.

 

What happens during surgery?

 

Most pulmonary hypertension patients receive a double lung transplant in a surgery lasting 8–12 hours.

 

Afterward, patients have a breathing tube in their airway and are attached to a ventilator until they are ready to breathe for themselves. Some may require temporary ECMO (heart-lung machine) support. Chest tubes are placed to allow air, fluid, and blood to drain away.

 

If all goes well, people stay in ICU for about a week and stay in hospital for about a month. Rehabilitation begins early.

 

What does life look like after transplant?

 

Transplant requires lifelong follow-up. Patients return to the hospital regularly for breathing tests, CT scans, bronchoscopies, and biopsies.

 

Immunosuppressive medications, taken to prevent rejection of the new lungs, must be continued for life, but they increase infection and cancer risk.

 

Chronic rejection—called chronic allograft dysfunction—remains the biggest long-term challenge. After transplant, people survive 7.5 to 8 years on average, though many live longer.

 

Dr. Granton describes transplant as “trading one disease for another.” PH is replaced with the chronic management of the transplant. For many patients, however, the trade is worth it. They experience less breathlessness and greater independence. Most, he says, would choose to do it again.

From not being able to walk up stairs on my own, to being able to play hockey, lift weights and maintain an active lifestyle—the power of transplant has not only given me independence but a chance to experience life like a normal person. Without the power of transplant, I would not be here today. Someone’s decision to donate gave me the opportunity to live.

​Hearing the words “It is time to discuss having a double lung transplant (DLT)” gets a person’s attention. When I was diagnosed with idiopathic pulmonary arterial hypertension (IPAH) in 2016, I knew that a DLT might be an option, but I thought I had many more good years ahead with my own lungs. My doctor explained I would need a “workup,” a battery of tests by the transplant team at Toronto General Hospital (TGH) to determine my candidacy and priority level. He urged me to start the process now so my condition wouldn’t progress to the point where I risked being ineligible. I decided to go ahead, considering it a "safety net" in case my condition declined. The workup took months, as I was also recovering from two strokes and already had a packed medical calendar. The tests were extensive: bone density scans, an echocardiogram, a right heart catheterization, a transesophageal echocardiogram, pulmonary function tests, and more. Finally, I travelled five hours to TGH to sign the listing papers. Making that trip made the safety net real. I wasn’t excited or scared; I just felt I had to do it. I have a little guy at home who needs his Mommy, and I will do anything in my power to make that happen. Until that point, I had pushed the beach ball that was my emotions underwater. That changed during the meeting with the thoracic surgeon. Hearing about the operation—the physical harm of cutting the body open—was difficult, even knowing it could save my life. But the biggest shock was the possible timing. I went to Toronto to set a safety net in place, not to take immediate action. When the surgeon said I could be transplanted in a few months, the beach ball of emotions I had been submerging broke loose, dampening my eyes. I wanted to try the new PAH treatment, sotatercept, and hopefully buy time before living with someone else’s lungs. My case manager called to tell me I was listed as Priority 2. I was expecting to be listed at Priority 1, the lowest urgency. At a physio session, a lady had asked when my husband had been transplanted, assuming he was the patient. When I walked at a good speed on the treadmill, it had shocked the patients around me and added to my disbelief about the urgency of the transplant. Being considered a more urgent case was an unwanted surprise. Thankfully, after advocacy from doctors, family, friends, politicians, Merck, and PHA Canada, I accessed sotatercept early, and it began helping me live better and longer with my own lungs. I pray that continues for me and my "PHellow PHighters." I am so grateful to have this chance. While I know I will one day need donor lungs, for now I am going to "PHight" my hardest with my own lungs

Side by Side in Hardship: Transplantation is a Journey for Two

My partner, Francisco, was diagnosed with pulmonary hypertension in 2010. He began experiencing symptoms of this degenerative disease in 2009 and it took a year before he received a proper diagnosis. Everything changed in our life at that moment. At the time, he was treated for right-heart failure and, after several hospitalizations at the Hull Hospital, he was finally transferred to the Jewish General Hospital in Montreal for more advanced tests. This is where we learned the bad news. Initially, when the doctor told me that my partner was suffering from PH, I did not know what it was. This disease is so rare that few people know about it. However, when I learned of all the implications of the disease, my world collapsed and I was devastated. The doctor explained to me that even with the drugs, the disease would continue to progress and as a last resort, Francisco would need a lung transplant. His life expectancy then was between four and six years. Learning to live with PH was difficult, both for him and for me. Our lifestyle changed completely. Physical activities and family walks, those were over for us. The disease was about to take away what is most essential to Francisco’s life: breathing. Seeing my partner always sick and losing his breath at the slightest effort made me feel helpless. It was a difficult reality to live with and I often had to hide so he wouldn’t see me cry in front of him. He often had to be hospitalized and the idea that I could lose him at any moment was very stressful. I was overcome by fear. The children asked me a lot of questions because they saw that their father was not in very good condition. In order not to worry them, I simply told them that he was suffering from a nasty flu. During my experience as a caregiver, there was a particularly touching moment. It was December 2015, and Francisco was then hospitalized at the Ottawa General Hospital. When I went to see him, he was very ill and the doctors told me that he had reached the last stage of the disease and could leave us at any time. He took my hand and said: “Do not worry, everything will be fine. I’ll get through it. I will stay strong for the kids and for you. I refuse to let myself go.” These words touched me deeply. It was a hard and very painful moment. But on the other hand, it was wonderful to see his strength and his will to fight in order to survive. The best part is that he was right. Francisco received a lung transplant on January 5, 2016. Before receiving his transplant, he was connected to an ECMO machine, which provides oxygenation through an extracorporeal membrane. This machine kept him alive because the oxygen level in his blood was very low and he had trouble breathing by himself. Transplant became his only option to survive and we had to fill out consent forms to start the process. We are residents of Gatineau, where there is no lung transplantation program, so my partner had to be relocated to Toronto to wait, receive, and recover from his lung transplant. We were separated for three months, during which I had to learn to live differently and manage my loneliness because normally we are inseparable. However, the most difficult thing was to see my children, who were eight and five at the time, suffer from his absence. Even though we talked to him every day via teleconference, they asked me regularly when Daddy would come back home. At their age, they had no sense of time and three months for them could seem like only a few days. I was very moved when I learned that lungs were available for Francisco. I was surprised and happy, and I jumped around like a child. My partner was admitted to Toronto General Hospital on December 28, 2015 and I got the news the morning of January 5th. For me, it was a miracle; he finally had two good lungs in perfect health! A precious gift of life. Throughout this ordeal, I was surrounded by my family and friends, this is what helped me get through it. I must particularly thank my sister-in-law, Tanya, and my brother-in-law, Roberto, who greatly helped and supported us. I was lucky to receive a lot of moral support and encouragement from them. Without their help, it would have been much more painful. Talking to my partner every day and learning of his progress also gave me the strength to move forward and smile along this journey. To a family in a situation similar to ours, I would say to not get discouraged and stay strong! We must never lose hope. I also believe that it is important to educate people to sign their card for organ donation, because life is the biggest gift we can give. It is thanks to Francisco’s transplant that a new life began for us. His health now allows him to live a normal life. We resumed a few of our activities such as taking walks and doing other exercises. He can finally be active without suffering from breathing difficulties. What a change! We are enjoying life to the fullest and are making plans for the future. This ordeal has brought us closer than ever and we want to get married. My partner will resume his studies and eventually return to work. We would like to travel and enjoy all the beautiful moments of life. It is so important.

Pulmonary Rehabilitation in Lung Transplant Candidates with PAH

2026 Connections research update article

Maha Munawar, Lisa Wickerson, Chaya Gottesman, Aislinn Braun, Sahar Nourouzpour, Marc de Perrot, Lianne G. Singer, Shaf Keshavjee, John Granton, and Dmitry Rozenberg. Pulmonary rehabilitation in lung transplant candidates with pulmonary arterial hypertension. Respiratory Medicine 2024, 234:107816. Background. We know supervised exercise training is safe and effective for people with mild or moderate pulmonary arterial hypertension (PAH), and we know that pre-transplant exercise capacity is associated with better outcomes and shorter hospital stays after lung transplants. But is pulmonary rehabilitation safe and effective for lung transplant candidates who have severe PAH? This study looked at how pulmonary rehabilitation affected people with severe PAH who were listed for lung transplants. Findings. Researchers studied 40 lung transplant candidates with PAH who attended a mandatory supervised outpatient pulmonary rehabilitation program three times per week for 90 minutes while awaiting transplants. These exercise sessions involved aerobic exercise on a treadmill or stationary bike and weight training for both upper body and lower body muscles. Participants increased their six-minute walk distance (6MWD) by an average of 18 metres while they were waiting (half waited more than 225 days, half for fewer) for a transplant. Measures of oxygen uptake, muscle volume, and the amount of oxygen people were able to use when exercising compared to the oxygen they used when sitting still all showed small but significant improvements. Measures for shortness of breath and leg fatigue did not change. Most participants’ hearts remained unable to fully compensate for exercise and participants were unable to increase their heart rates enough with exercise. There were no major safety incidents related to the exercise training. Implications. This study established that participants listed for lung transplant and who participated in pulmonary rehabilitation safely maintained or improved their exercise capacity despite the significant symptoms associated with severe pulmonary arterial hypertension. A 6MWD increase of 18 metres was not statistically relevant. However, other studies found decreases in 6MWD in similar participants over shorter time periods, so researchers in this study felt that participants ability to maintain their 6MWD while awaiting transplant was positive. Future studies should look at post-transplant outcomes. They should also examine at-home and hybrid exercise programs as well as in-person programs and should look at the best ways for participants to resume pulmonary rehabilitation after a hospitalization.
