Pulmonary Atresia

Overview

Pulmonary Atresia is a serious congenital heart defect in which the pulmonary valve, responsible for allowing blood flow from the heart to the lungs, does not form properly. As a result, blood cannot flow normally from the right ventricle to the lungs to receive oxygen.

This condition is present at birth and requires early diagnosis and specialized medical care. Without treatment, it can lead to severe complications, but with timely intervention, outcomes can be significantly improved.

At Moolchand Hospital, a leading multi super speciality hospital in Delhi, patients receive advanced care for complex congenital heart conditions. Recognised as a trusted heart hospital in Delhi and a well-established hospital in Lajpat Nagar Delhi, Moolchand offers comprehensive pediatric and adult cardiac services.

What is Pulmonary Atresia?

Pulmonary atresia occurs when the pulmonary valve is either absent or severely underdeveloped. This prevents blood from flowing directly from the heart to the lungs.

Instead, the body relies on alternative pathways, such as the ductus arteriosus, to supply blood to the lungs. This abnormal circulation requires urgent medical management soon after birth.

Symptoms of Pulmonary Atresia

Symptoms usually appear shortly after birth and may include:

• Bluish discoloration of skin and lips (cyanosis)
• Rapid or difficult breathing
• Fatigue or poor feeding in infants
• Low oxygen levels
• Weak pulse or poor growth

This is a medical emergency that requires immediate attention.

Causes of Pulmonary Atresia

Pulmonary atresia is a congenital condition, meaning it develops before birth. The exact cause is not always known, but it may be associated with:

• Abnormal heart development during pregnancy
• Genetic factors
• Other congenital heart defects

Risk Factors

Factors that may increase the risk include:

• Family history of congenital heart disease
• Maternal infections during pregnancy
• Exposure to certain medications or substances during pregnancy
• Genetic syndromes

When Should You See a Doctor?

Immediate medical care is required if a newborn shows:

• Blue or pale skin
• Breathing difficulties
• Feeding problems
• Signs of low oxygen levels

Early diagnosis and intervention are critical.

Diagnosis of Pulmonary Atresia

Doctors may use:

• Echocardiography (key diagnostic test)
• Pulse oximetry
• Chest X-ray
• Electrocardiogram (ECG)
• Cardiac catheterization

At Moolchand Hospital Delhi, advanced cardiac diagnostics help identify the condition quickly and accurately.

Treatment Options for Pulmonary Atresia

Treatment depends on the severity and associated heart defects.

1. Medications

Medications such as prostaglandins may be used to keep blood flow pathways open after birth.

2. Catheter-Based Procedures

Minimally invasive procedures may help improve blood flow.

3. Surgical Treatment

Surgery is often required to create or restore normal blood flow to the lungs.

4. Long-Term Cardiac Care

Multiple procedures or surgeries may be needed over time for optimal heart function.

At Moolchand Hospital, a leading best cardiac hospital in Delhi, experienced specialists provide comprehensive treatment for complex congenital heart conditions.

Complications of Pulmonary Atresia

If untreated, pulmonary atresia can lead to:

• Severe oxygen deficiency
• Heart failure
• Delayed growth and development
• Life-threatening complications

Early treatment significantly improves survival and quality of life.

Prevention and Care

While pulmonary atresia cannot always be prevented, supportive care includes:

• Regular prenatal check-ups
• Early diagnosis after birth
• Long-term follow-up with cardiac specialists
• Adherence to treatment plans
