Pulmonary Hypertension Treatment: When Is Balloon Pulmonary Angioplasty Considered?

Pulmonary hypertension treatment depends on the cause, severity, and how the pressure affects the heart and lungs. Balloon pulmonary angioplasty is considered mainly for carefully selected people with chronic thromboembolic <a href="https://acibademinternational.com/diseases/pulmonary-hypertension/”>pulmonary hypertension, especially when surgery is not possible or when symptoms remain after surgery.

Overview: what pulmonary hypertension treatment aims to do

Pulmonary hypertension is a condition in which the blood pressure inside the arteries of the lungs becomes abnormally high. Over time, this can make it harder for the right side of the heart to pump blood forward. Pulmonary hypertension treatment focuses on lowering strain on the heart, improving breathing and exercise capacity, and treating the underlying cause whenever possible.

It is important to know that pulmonary hypertension is not a single disease. It includes several different groups of disorders. Some are related to lung disease, some to heart disease such as heart failure, some to connective tissue disorders, and some to chronic blood clots in the lungs. Because of this, the best treatment can vary greatly from one person to another.

Balloon pulmonary angioplasty, often called BPA, is a minimally invasive catheter-based procedure used in selected patients with chronic thromboembolic pulmonary hypertension, or CTEPH. In this form of pulmonary hypertension, old blood clots do not fully clear and instead leave behind scar-like narrowings or blockages in the pulmonary arteries. BPA can help open some of these narrowed vessels and improve blood flow.

BPA is usually considered only after detailed testing and review in a specialized center. For some patients, surgery called pulmonary endarterectomy may be the preferred treatment. For others, BPA becomes an option when surgery is not feasible, the disease is located in smaller vessels, or pulmonary hypertension continues after surgery.

Symptoms and how the condition may affect daily life

The symptoms of pulmonary hypertension often develop gradually and can be mistaken for other heart or lung conditions. Shortness of breath during activity is one of the most common symptoms. People may also notice unusual fatigue, reduced exercise tolerance, chest discomfort, lightheadedness, or swelling in the ankles and legs.

In CTEPH, symptoms can persist even months after a pulmonary embolism, or they may appear without a clearly recognized blood clot event. Some people also describe a racing heartbeat or awareness of their heartbeat, although these symptoms can have many causes, including heart palpitations that need separate evaluation.

As the disease progresses, everyday tasks such as climbing stairs, walking uphill, or carrying groceries may become more difficult. Some patients begin avoiding activity because they feel breathless or tired, which can gradually reduce strength and stamina further.

Symptoms alone cannot show whether BPA is needed. However, ongoing breathlessness, exercise limitation, and signs of strain on the right side of the heart can prompt testing for pulmonary hypertension and its underlying cause. A clear diagnosis is the key step before any procedure is considered.

Causes, risk factors, and who may be a candidate for balloon pulmonary angioplasty

Pulmonary hypertension has many possible causes. It may be associated with left-sided heart disease, chronic lung disease, sleep-related breathing problems, connective tissue disorders, congenital heart disease, liver disease, or chronic blood clots. BPA is not a routine treatment for all of these. Its main role is in chronic thromboembolic pulmonary hypertension, where old clots or fibrotic material obstruct blood flow in the pulmonary arteries.

CTEPH can develop after one or more episodes of pulmonary embolism, although not every person recalls a past clot. Risk factors may include a history of venous blood clots, clotting disorders, certain inflammatory conditions, prior splenectomy, long-term intravascular devices, and some chronic medical illnesses. People with a history of deep vein thrombosis treatment and follow-up may be evaluated carefully if persistent breathlessness develops after a clotting event.

A patient may be considered for BPA when imaging shows chronic organized blockages in pulmonary arteries that are technically reachable with balloons, but surgery is not suitable or is judged too high risk. BPA may also be considered when residual pulmonary hypertension remains after pulmonary endarterectomy. The decision is individualized and based on the pattern of disease, symptoms, hemodynamic findings, and overall health.

Not every narrowed vessel should be opened, and not every patient benefits in the same way. Experienced centers usually discuss each case in a multidisciplinary team that may include pulmonary hypertension specialists, interventional cardiologists or radiologists, imaging experts, cardiothoracic surgeons, and anesthesiology teams. This team approach helps choose between medicines, surgery, BPA, or a combination of treatments.

How doctors diagnose pulmonary hypertension and plan BPA

The diagnosis of pulmonary hypertension usually starts with a careful medical history, physical examination, blood tests, chest imaging, electrocardiogram, and echocardiography. These tests can suggest elevated pressure in the lung circulation and show whether the right side of the heart is under strain. They also help look for common causes such as lung disease or left-sided heart problems.

When CTEPH is suspected, ventilation-perfusion scanning and specialized CT pulmonary angiography are often used to look for chronic blockages in the pulmonary arteries. Detailed imaging helps show where the disease is located and whether the affected vessels may be suitable for BPA. In some cases, catheter-based imaging and pulmonary angiography may be needed as part of advanced planning, similar in principle to other procedures performed in invasive cardiology.

Right heart catheterization is a central part of diagnosis. It directly measures pressures in the heart and pulmonary arteries and helps confirm the severity of pulmonary hypertension. This test is especially important because treatment decisions should not be based on symptoms or echocardiography alone.

Doctors also assess functional status, oxygen needs, other medical conditions, and whether surgery is possible. Because BPA carries specific risks and is often done in stages, the center must be able to monitor patients closely before, during, and after each session. Careful planning greatly improves safety and helps decide whether BPA is the right option.

When balloon pulmonary angioplasty is considered

Balloon pulmonary angioplasty is usually considered in people with inoperable CTEPH or persistent pulmonary hypertension after surgery. “Inoperable” may mean that the blockages are too far out in the smaller branches of the pulmonary arteries for surgical removal, or that the patient has health factors that make surgery unsuitable. BPA may also be chosen when symptoms remain despite medication and anticoagulation.

During BPA, a thin catheter is guided into selected pulmonary artery branches, and a very small balloon is inflated to widen narrowed segments. The goal is to improve blood flow through obstructed areas without causing vessel injury. Because many patients have multiple affected segments, treatment is commonly performed over several sessions rather than all at once.

Modern BPA has become safer with refined techniques, careful patient selection, and staged treatment strategies. Even so, it remains a specialized procedure that should be done by teams with experience in pulmonary vascular disease. It is different from treatments aimed at other cardiovascular problems such as coronary angiography for coronary arteries or operations for coronary artery disease.

Before recommending BPA, doctors weigh expected benefits against potential risks such as lung vessel injury, bleeding into the lung, low oxygen levels, irregular heart rhythm, contrast-related effects, and complications related to catheter procedures. This discussion helps patients understand why BPA may be appropriate, why another treatment may be better, or why a combination approach may be advised.

Other treatment options and what to expect after the procedure

Pulmonary hypertension treatment often includes more than one strategy. In CTEPH, lifelong anticoagulation is usually recommended unless there is a clear reason it cannot be used. Some patients also receive targeted pulmonary hypertension medications to improve symptoms and blood flow dynamics, especially before BPA, between staged sessions, or when residual pulmonary hypertension remains.

For suitable patients, pulmonary endarterectomy is often considered the standard treatment because it can remove chronic clot material from larger pulmonary arteries. BPA is generally used when surgery is not possible, when disease is more distal, or when surgery does not fully resolve pulmonary hypertension. Oxygen therapy, diuretics for fluid retention, and supervised cardiac rehabilitation or exercise-based rehabilitation may also support recovery and quality of life.

After a BPA session, patients are monitored for breathing status, oxygen levels, and signs of lung injury or bleeding. Follow-up often includes repeat imaging, echocardiography, blood tests, and sometimes repeat right heart catheterization. Improvement can be gradual because treatment is frequently staged over multiple procedures.

Long-term care remains important even when symptoms improve. Patients still need regular specialist follow-up, attention to blood thinner use, and review of other heart or blood pressure conditions, including systemic hypertension care when present. Near the end of the care pathway, some international patients may choose centers such as Acibadem International, where multidisciplinary specialists and JCI-accredited hospitals diagnose and treat pulmonary vascular conditions using individualized plans.

Self-care, prevention, and when to seek medical attention

There is no simple way to prevent all forms of pulmonary hypertension, but early evaluation of unexplained breathlessness can help people receive the right diagnosis sooner. In CTEPH, prompt treatment of blood clots, consistent anticoagulation when prescribed, and follow-up after pulmonary embolism are important. People should take medicines exactly as directed and not stop blood thinners without medical advice.

General self-care can support overall heart and lung health. This may include staying as active as a doctor recommends, avoiding smoking, attending rehabilitation if advised, keeping up with vaccinations, and discussing travel, pregnancy, altitude exposure, or planned surgery with a specialist. Patients should also ask whether oxygen is needed during exercise or flights.

Medical review is important if there is worsening shortness of breath, chest pain, fainting, new swelling, coughing up blood, or symptoms suggesting another clot such as sudden leg swelling or pain. These do not always mean a serious emergency, but they should be assessed promptly because they may indicate progression or a complication.

Anyone being considered for BPA should feel comfortable asking why it is being recommended, what alternatives exist, how many staged sessions may be needed, and what follow-up will involve. Clear communication with an experienced team helps patients make informed choices and feel more confident about treatment.

Frequently asked questions

Is balloon pulmonary angioplasty used for all types of pulmonary hypertension?

No. Balloon pulmonary angioplasty is mainly used for chronic thromboembolic pulmonary hypertension, which is caused by persistent clot-related blockages in the lung arteries. It is not a standard treatment for most other forms of pulmonary hypertension.

How do doctors decide between surgery and BPA?

The decision depends on where the blockages are located, how severe the pulmonary hypertension is, and the patient’s overall health. Larger, surgically accessible blockages may be better treated with pulmonary endarterectomy, while more distal or inoperable disease may be considered for BPA.

Is BPA a one-time procedure?

Often, no. BPA is commonly performed in stages over several sessions because multiple lung artery branches may need treatment and a gradual approach can improve safety. The exact number of sessions varies by the pattern of disease and the person’s response.

What tests are needed before BPA?

Assessment usually includes echocardiography, detailed lung vessel imaging, and right heart catheterization. Doctors may also order blood tests, oxygen assessment, and functional evaluations to confirm the diagnosis and plan the safest treatment approach.

Can symptoms improve after balloon pulmonary angioplasty?

Many patients experience improvement in breathlessness, exercise tolerance, and pressure measurements after successful treatment. However, results vary, and some people still need medicines, oxygen, or additional procedures as part of long-term care.

What are the main risks of BPA?

Possible risks include injury to the pulmonary artery, bleeding into the lungs, low oxygen levels, contrast-related effects, and other catheter-procedure complications. These risks are one reason BPA should be performed in experienced centers with careful monitoring.
