Lung Transplant in Pulmonary Hypertension: When Is It Needed?

Pulmonary hypertension (PH) is a serious, progressive, and chronic condition that puts immense strain on both the lungs and the heart. Over time, the immense pressure on pulmonary arteries makes it difficult for the heart to pump blood efficiently through the lungs, causing worsening symptoms in the patient.

Beyond medications and interventional therapies, patients whose PH have progressed severely, might need to consider lung transplantation as a life-saving measure.

If you are wondering about lung transplant in pulmonary hypertension, its candidature, outcomes, healing and recovery, this guide from Dr. Arvind Kumar will explore it all.

What is Pulmonary Hypertension?

Pulmonary hypertension (PH) is a condition where the patient has abnormally high blood pressure in the pulmonary arteries.

In PH patients, the pulmonary arteries become narrowed, stiff or blocked, which makes it difficult for the blood to flow seamlessly, which, in turn, causes the blood pressure to spike. As a result of this:

• The right side of the heart works harder to pump blood through the lungs
• The heart muscle gradually becomes enlarged and weakened
• Oxygen delivery to the body becomes compromised

If not diagnosed early and not treated on time, this consistent strain leads to right-sided heart failure, which is a potentially life-threatening complication. What you also need to understand is that pulmonary hypertension is a group of disorders, all of which share the same characteristic of elevated pressure in the pulmonary arteries.

What are the Types and Causes of Pulmonary Hypertension?

There are a plethora of reasons that could contribute to the onset, development and progression of pulmonary hypertension.

The table below provides a simplified overview of the major types and their common causes:

Identifying what type of pulmonary hypertension you have is vital, which explains why Dr. Arvind Kumar emphasises on early diagnosis and personalised interventions to help restore the patient’s quality of life.

What are the Common Symptoms of Advanced PH?

In the initial stages, pulmonary hypertension might develop gradually and the symptoms might be mild. However, with disease progression, the symptoms tend to become worse and start hindering the patient’s daily activities.

Some of the common symptoms to not ignore are:

• Persistent shortness of breath, especially during physical activity
• Fatigue and weakness
• Chest pain or pressure
• Dizziness or fainting spells
• Swelling in the ankles, legs, or abdomen
• Rapid or irregular heartbeat
• Bluish discoloration of lips or skin due to low oxygen levels

If your pulmonary hypertension isn’t diagnosed and managed on time, these symptoms might worsen to a point where lung transplantation remains the only viable treatment option.

When Is a Lung Transplant Considered for Pulmonary Hypertension?

Now, the question of the hour is, “When does a patient with PH need a lung transplant?” Usually, if the patient has undergone one or more conventional treatments for pulmonary hypertension and none of them have controlled the hypertension effectively, that’s when transplantation is a viable choice.

Dr. Arvind Kumar, after the initial consultation, might evaluate you for transplantation if you are experiencing:

• Progressive disease despite maximum medical therapy
• Severe limitation in daily activities
• Recurrent hospitalisations due to worsening symptoms
• Signs of right heart failure
• Poor oxygen levels despite treatment

Not just that, Dr. Kumar and his team will also assess your overall health, including your heart and kidney function and other underlying chronic ailments. Our goal is to identify who’d benefit the most from the transplantation and then customize the treatment plan accordingly.

Types of Transplantation for Pulmonary Hypertension

Coming to the types of transplantation that PH patients might need to consider. Usually, for pulmonary hypertension patients, two primary types of transplantations are considered: Double lung transplant cost in India  (Bilateral) or, in specific cases, a Heart-Lung Transplant.

1. Double Lung Transplant

This is the most common procedure for PH. Even though the primary issue is the high pressure in the arteries, replacing both lungs provides a “low-resistance” vascular bed. Interestingly, once the new lungs are in place, the overworked right ventricle of the heart often begins to remodel and recover its function over time, despite years of strain.

2. Heart-Lung Transplant

This is reserved for patients who have developed irreversible left-sided heart disease or have complex congenital heart defects that cannot be repaired during a lung-only transplant. Because donor organs for heart-lung blocks are rare, Dr. Arvind Kumar prioritises double lung transplants whenever the heart’s recovery is deemed possible.

You’d need to undergo a pre-transplantation evaluation to determine your general health and the ideal treatment option for you.

Evaluation Process Before Lung Transplant for Pulmonary Hypertension

Once your symptoms of PH qualify you for a transplant, the first step before the actual surgery is to get a detailed evaluation. This extension procedure determines whether you are a suitable and healthy candidate for the transplant or not.

This process involves:

1. Detailed medical assessment

The first step in the evaluation starts with detailed medical assessment to evaluate the severity of PH and the overall health of the patient. This is done through tests like pulmonary function tests, echocardiography, right heart catheterization, CT scans, blood tests, infection screening, etc.

2. Cardiac evaluation

Since pulmonary hypertension directly impacts the right side of the heart and its functions, a detailed cardiac evaluation is also necessary.

3. Lifestyle assessment

Finally, during the pre-transplant stage, your surgeon will also advise you to stop smoking, improve your diet and prioritise physical rehabilitation.

Once the entire evaluation process is complete, the patients who qualify for the lung transplant procedure are then placed on the organ transplant waiting list.

How is Recovery and Life After Lung Transplant?

Recovery and healing after your lung transplant surgeon procedure is gradual and requires patience, discipline, and close medical supervision.

Here’s how we define the recovery period:

1. Immediate recovery

After the transplantation surgery, you’d remain in the hospital, under observation, for several days to weeks, depending on your health and how your body is responding to the new organ. During this period, your surgeon will monitor your lung function, oxygen levels, signs of infection and possibilities of organ rejection.

Also, during this period, you’d also start physical therapy, under supervision, to help you regain strength and improve your breathing capacity.

2. Long-term care

Once you are discharged from the hospital, there are certain dos and don’ts that Dr. Arvind Kumar and his team will mention, which you need to follow. This includes medical guidelines regarding:

• Lifelong immunosuppressant medications
• Regular follow-up visits
• Routine lung function tests
• Infection prevention measures

Following all the advised recovery protocols after the transplantation is crucial for quicker and steady recovery.
