Pulmonary Stenosis

Pulmonary stenosis is a narrowing at or near the pulmonary valve that makes the right side of the heart work harder. It is usually present from birth.

About pulmonary stenosis

What to know

Mild cases cause no symptoms and are found by a heart murmur. Moderate or severe narrowing can cause breathlessness, tiredness, chest pain or fainting on exertion. Diagnosis is by echocardiography, which measures the pressure across the valve, and sometimes cardiac MRI or catheterisation. Mild stenosis often stays stable for life, while severe stenosis can strain and thicken the right ventricle.

Mild stenosis needs only regular monitoring. Moderate to severe valvular stenosis is usually treated with balloon valvuloplasty through a catheter, which works well in most children and adults with a flexible valve. If the valve is thickened, or leaks badly after earlier repair, surgical valve repair or replacement is needed, now sometimes with a catheter-delivered valve. Families sometimes travel abroad for specialist congenital heart care.

Pre-flight workup

Tests to have already done

  • Echocardiogram report with the pressure gradient across the valve, valve structure and right ventricle size.
  • ECG and chest X-ray reports, and cardiac MRI if available to assess the right ventricle.
  • Cardiac catheterisation findings if done, with pressure measurements.
  • Records of any earlier balloon valvuloplasty or surgery, with dates and valve type.
  • Symptom history such as breathlessness, fainting or fatigue, and details of exercise capacity.

Second opinion

When to get a second look

  • Intervention is advised but the gradient is mild and symptoms are absent, since mild stenosis often needs only monitoring.
  • Valve replacement is proposed and you want to compare options such as a catheter-delivered valve and surgery.
  • You have had previous valve surgery and symptoms or leakage are returning.
  • The valve narrowing is part of a wider congenital syndrome, such as Noonan syndrome or tetralogy of Fallot.

Talking to your doctor

Questions to ask

  1. How severe is my narrowing, and what is the pressure gradient?
  2. Is the valve itself or the area above or below it the problem?
  3. Is balloon valvuloplasty enough, or do I need replacement?
  4. What type of replacement valve would you use, and how long will it last?
  5. Are exercise, pregnancy or sport safe for me?
  6. How often will I need echocardiograms?

Outlook

Realistic prognosis

Mild pulmonary stenosis often never needs treatment and has an excellent outlook. Moderate to severe stenosis usually responds well to balloon valvuloplasty, with good long-term results in valves that are not thick or abnormal. Replacement valves wear over time, so repeat procedures may be needed. Lifelong cardiology follow-up is advised, and outcomes depend on severity and valve type.

Diagnostic workup

Before you pick a hospital, get the workup right

Moderate — workup within 1–2 weeks

Picking the right treatment is downstream of a complete diagnosis. Skip steps here and the destination surgeon usually re-orders them anyway — at higher cost and another week on the ground.

  1. Confirm the diagnosis on imaging or labs

    For pulmonary stenosis, plan on the workup your home doctor would order anyway — typically a recent specialist consult plus the imaging / labs the destination team will need to quote accurately. Anything older than 90 days usually gets re-done.

  2. See a cardiac surgery specialist locally first

    An in-person clinical exam at home — even a single consult — costs little and dramatically improves the destination plan. Bring back: written impression, recommended procedure, surgical-risk class, and any contra-indications.

  3. Send us the file for a free second opinion

    Two surgeons in our medical panel review the workup independently. They tell you whether they'd operate, watch, or refer — even if that means recommending against travel.

  4. Pick a path with timeline + cost in writing

    Once a treatment is the right call, we line up 2–3 hospital options with itemized quotes, surgeon profiles, and a travel timeline. You hold the file — switch hospitals or step away at any point.

04 · FAQ

Common questions about pulmonary stenosis

Does pulmonary stenosis always need a procedure?

No. Mild stenosis is usually just monitored. Treatment is advised when the gradient is high or symptoms or heart strain appear.

Is balloon valvuloplasty enough?

It works well for many valves that are not thick, and avoids surgery. Valves that are heavily thickened or dysplastic may need surgery.

Can I be active or play sport?

Many people with mild or treated stenosis exercise normally. Ask your cardiologist about limits if the stenosis is moderate or severe.

Will I need follow-up for life?

Yes, usually. Valves can narrow again or leak, and the right ventricle needs checking with periodic scans.

Clinical context

Working up pulmonary stenosis properly

A condition like pulmonary stenosis is rarely well-served by jumping straight to treatment shopping. The sequence below is what a cardiac surgery specialist would expect to see completed — and the absence of any step is the right cue to delay travel decisions.

Diagnostic workup, in sequence

  1. First-line clinical assessment

    History, physical exam, and risk-factor review by a senior generalist or cardiac surgery specialist. Symptoms list, family history, prior workup notes, and current medication list should travel with the patient.

  2. Standard imaging + labs

    Baseline blood work, condition-specific imaging (ultrasound / X-ray / MRI / CT — depending on indication), and ECG / pulmonary function as relevant. Bring digital copies of any prior imaging — saves repeat scans and the cost that goes with them.

  3. Specialist diagnostic workup

    Procedure-specific tests — biopsy, cardiac catheterisation, endoscopy, or genetic / molecular profiling depending on the suspected diagnosis. Done at the centre that will treat, ideally, so results integrate cleanly into the treatment plan.

  4. Multidisciplinary review (where indicated)

    Cancer, complex cardiac, transplant, and rare-disease cases should be reviewed by a multidisciplinary panel — surgical, medical, imaging, and pathology — before any treatment commits. Single-discipline plans for complex disease are a quality red flag.

When to escalate to specialist review

  • New, persistent, or worsening symptoms beyond the usual pattern — particularly anything that disrupts work, sleep, or daily function for >2 weeks.
  • Symptoms accompanied by red-flag features (unintentional weight loss, night sweats, bleeding, severe pain, neurological signs).
  • Any "this feels different" instinct — especially with recurrent or chronic conditions where you know your baseline well.
  • A second-opinion misalignment with your current care plan — when two qualified clinicians disagree, the case warrants a third review before committing.

Before you book international travel

  • Confirm your specific diagnosis is fully worked up before you commit to a treatment plan abroad. Travelling for the workup is fine; travelling for treatment without the workup done is not.
  • Get your case reviewed remotely by the destination centre's team before you book flights — credible international patient programs review imaging + reports before they confirm the surgical plan.
  • Bring a digital + physical copy of your full medical record: imaging on USB drive in DICOM format, labs in PDF, current medication list with dosages, allergies, and any prior surgical reports.
  • Plan for the post-op rehabilitation phase before you fly — the surgery itself is rarely the bottleneck.
  • Confirm that follow-up imaging and any necessary in-person reviews can be done at home — a treatment plan that requires repeat international trips is more burdensome (and more expensive) than the headline procedure.
