Hypoplastic Left Heart Syndrome
Hypoplastic left heart syndrome is a serious congenital heart defect in which the left side of the heart, including the left ventricle and aorta, is underdeveloped. The right side must supply blood to both lungs and body.

About hypoplastic left heart syndrome
What to know
It is often detected on the mid-pregnancy scan. Without prenatal diagnosis, newborns become pale, breathless and shocked as the ductus arteriosus closes. Echocardiography confirms the diagnosis. It is fatal without treatment, and survival now depends on a staged surgical pathway.
Treatment is a series of three operations. The Norwood procedure in the first days of life reconstructs the circulation, the Glenn (bidirectional cavopulmonary shunt) at about four to six months connects the upper body veins to the lungs, and the Fontan procedure at two to four years completes the circuit. Medicines and lifelong cardiology follow-up are needed. Heart transplant is an alternative. Care is concentrated in specialist paediatric heart centres.
Pre-flight workup
Tests to have already done
- Fetal and postnatal echocardiogram reports describing the valves, ventricle size and the aortic arch.
- Cardiac catheterisation or CT/MRI reports with pulmonary artery sizes and pressures.
- Operation notes and discharge summaries for any Norwood or other stage already done, including bypass times.
- Current oxygen saturations, weight gain and feeding plan, medicines and any rhythm problems.
- Genetic testing results and tests for other organ problems, if performed.
Second opinion
When to get a second look
- You are weighing a staged repair against transplant or comfort care and want to hear the options from another centre.
- Your child has poor heart function, a leaky valve or low oxygen levels between stages.
- A Fontan is planned and pulmonary pressure or ventricle function results are borderline.
- Your child is having complications such as protein-losing enteropathy, rhythm problems or feeding difficulty.
Talking to your doctor
Questions to ask
- Which stage is my child at, and what operation comes next and when?
- How well is the right ventricle working, and are the valves leaking?
- What are the risks of each stage in your centre?
- What warning signs between stages need urgent care?
- When might transplant be considered?
- What will long-term follow-up involve?
Outlook
Realistic prognosis
HLHS is life-threatening without treatment. With staged surgery in experienced centres, most children survive the early stages, though the first operation carries the highest risk. Survival to adulthood is now common, but the single-ventricle circulation tends to wear out over time and long-term problems include heart failure, rhythm disturbance and liver or gut complications. Some children eventually need a heart transplant. Lifelong specialist follow-up is essential.

Diagnostic workup
Before you pick a hospital, get the workup right
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.
- Confirm the diagnosis on imaging or labs
For hypoplastic left heart syndrome, 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.
- 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.
- 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.
- 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 hypoplastic left heart syndrome
Why are three operations needed?
The surgeries progressively re-route blood so that the single right ventricle supplies the body, and the lungs are supplied passively. Each stage is done as the child grows.
Can my child lead a normal life?
Many children go to school and are active, with limits on strenuous exertion. Lifelong cardiology follow-up is required.
Is a heart transplant an option?
Yes, it is an alternative at the start or later if the single ventricle fails, but donor hearts for infants are scarce.
Can we travel between stages?
Travel between stages can be risky because oxygen levels and feeding are fragile. Only travel with your cardiologist's explicit clearance.
Clinical context
Working up hypoplastic left heart syndrome properly
A condition like hypoplastic left heart syndrome 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
- 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.
- 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.
- 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.
- 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 urgently
- Acute worsening of established symptoms — sudden chest pain, shortness of breath at rest, neurological deficit, severe bleeding, persistent high fever.
- Loss of consciousness, severe persistent vomiting, or any focal neurological event.
- Symptoms in the early hours of onset that fit a time-sensitive treatment window (stroke, MI, sepsis) — every hour costs outcome.
- If you are travelling internationally for treatment and develop these symptoms in transit, divert to the nearest emergency department; do not wait to reach the planned destination.
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.
