Patent Ductus Arteriosus (PDA): Causes, Symptoms and Treatment in Kolkata

A detailed discussion on ‘Patent Ductus Arteriosus (PDA): Causes, Symptoms and Treatment in Kolkata’ by Dr. Debasree Gangopadhyay, pediatric cardiologist (MD), Narayana Hospital, Mukundapur, Kolkata.

Introduction

Patent Ductus Arteriosus (PDA) is a congenital heart condition that mainly affects newborn babies and young children. It happens when a small blood vessel in the heart, which is normal before birth, does not close after the baby is born. Because of this, extra blood flows to the lungs, and the heart has to work harder than usual. If not detected and treated on time, PDA can lead to breathing problems, poor growth, and other heart-related complications.

Understanding the causes, symptoms, and treatment of PDA helps parents take the right steps at the right time. With early diagnosis and proper medical care, most children with PDA can recover well and lead a healthy life. Today, advanced medical facilities and experienced specialists make Patent Ductus Arteriosus (PDA) Treatment in Kolkata both safe and effective. The city has well-equipped hospitals and skilled doctors who regularly manage congenital heart conditions in children.

If you’re in Kolkata, consulting an experienced Pediatric Cardiologist in Kolkata is important for accurate diagnosis and choosing the most suitable treatment option, whether it is medication, catheter-based closure, or surgery. In this blog, we will explain Patent Ductus Arteriosus (PDA)along with its causes, symptoms, and line of treatment in a simple way to help parents make informed decisions for their child’s heart health.

Understanding Patent Ductus Arteriosus (PDA): A Complete Guide

When you hear your child has a heart condition, your world might feel like it’s turned upside down. But here’s the thing—not all heart conditions are created equal, and some, like Patent Ductus Arteriosus, are highly treatable if detected early. Let me walk you through everything you need to know about this condition, from what causes it to how it’s treated, especially if you’re looking for care in Kolkata.

What is congenital heart disease?

Congenital heart disease (CHD) refers to heart problems that are present at birth. These conditions develop while the baby is still growing in the mother’s womb. Some congenital heart diseases are mild and may not cause serious issues, while others need timely medical care. One common example of congenital heart disease is Patent Ductus Arteriosus (PDA).

What Is Patent Ductus Arteriosus?

Patent Ductus Arteriosus (PDA) is a congenital heart condition that is present from birth. Before a baby is born, there is a small blood vessel called the Ductus Arteriosus that connects two major arteries of the heart. This vessel is important for blood circulation in the womb. After birth, when the baby starts breathing on their own, this blood vessel is supposed to close naturally within a few days.

When the Ductus Arteriosus does not close and remains open, the condition is called Patent Ductus Arteriosus. Because of this opening, extra blood flows to the lungs, making the heart work harder than normal. If not treated on time, PDA can lead to breathing problems, poor growth, and heart strain. With early diagnosis and proper Patent Ductus Arteriosus (PDA) Treatment in Kolkata, most children recover well and lead healthy lives.

Why Does PDA Occur? Understanding the Causes

PDA occurs when the Ductus Arteriosus fails to close after birth. One of the most common reasons is premature birth, as the baby’s heart may not be fully developed to trigger natural closure. Low birth weight is also linked to a higher risk of PDA.

Other possible causes include genetic factors, family history of congenital heart disease, and certain infections during pregnancy. PDA is also seen more often in baby girls than boys. In many cases, the exact cause is not clearly known.

Understanding why PDA occurs helps in early detection and timely care. With the availability of advanced Patent Ductus Arteriosus (PDA) Treatment in Kolkata, children with PDA can receive the right treatment at the right time, reducing the risk of long-term complications.

Here we will explain the causes for Patent Ductus Arteriosus (PDA):

Normal Fetal Heart Development

To understand why PDA happens, we need to rewind to before birth. Inside the womb, a baby doesn’t breathe air—oxygen comes from the mother through the umbilical cord. The Ductus Arteriosus acts as a shortcut, diverting blood away from the lungs since they’re not yet needed for oxygen exchange.

When the baby is born, everything changes in an instant. With that first cry, the lungs expand, oxygen fills them, and a series of chemical changes signal the Ductus Arteriosus to close. Usually, this happens within 48 to 72 hours after birth. But in some babies, especially premature ones, this closure doesn’t happen as it should.

Other Risk Factors for PDA

Several factors come into play. Premature birth is the biggest risk factor—the earlier a baby is born, the higher the chance the Ductus Arteriosus will remain open. Babies born before 28 weeks of pregnancy have a particularly high risk.

Genetic factors also play a role. If there’s a family history of congenital heart defects, the risk increases. Girls are also slightly more likely to have PDA than boys, in many cases, the exact cause is not clearly known.

Certain conditions during pregnancy can increase the risk too. If a mother has rubella (German measles) during pregnancy, uses certain medications, or has poorly controlled diabetes, the baby’s risk of PDA goes up. High-altitude births have also been associated with a higher incidence of PDA, possibly due to lower oxygen levels.

Recognizing the Symptoms of Patent Ductus Arteriosus

The symptoms of Patent Ductus Arteriosus (PDA) are related to how much blood flows through the persistent opening. Small PDAs may not show symptoms at all, while larger defects usually cause noticeable problems.

Common Symptoms in Babies

• Rapid or heavy breathing
• Sweating a lot, even during feeding
• Poor weight gain or growth delays
• Getting tired easily while feeding or playing
• A heart murmur (an unusual sound heard with a stethoscope)
• Fast heartbeat

These symptoms occur because extra blood is being pushed into the lungs and heart, making them work harder than normal.

If you notice any of these signs in your baby or child, it’s important to talk to a doctor — especially a Pediatric Cardiologist in Kolkata. Early diagnosis and treatment can prevent complications.

How Is PDA Diagnosed?

Patent Ductus Arteriosus (PDA) is usually diagnosed through a careful medical check-up and a few simple tests. Doctors often first suspect PDA when they hear an unusual heart sound, called a heart murmur, during a routine examination of a baby or child.

Doctors use some of the tests to diagnose PDA:

Echocardiogram (heart ultrasound):To confirm the diagnosis, an echocardiogram (heart ultrasound) is commonly done. This test shows the structure of the heart, how blood flows through the heart and helps the doctor clearly see the open Ductus Arteriosus.

Electrocardiogram (ECG): Measures the heart’s electrical activity.An ECG (electrocardiogram) helps understand the heart’s rhythm.

Chest X-ray:A chest X-ray may be used to check the size of the heart and lungs.

Accurate diagnosis is crucial for deciding Patent Ductus Arteriosus (PDA) treatment and the next steps. Once PDA is confirmed, doctors can decide the best approach for care, including options for Patent Ductus Arteriosus (PDA) Treatment in Kolkata, based on the child’s age, symptoms, and overall heart health.

Patent Ductus Arteriosus (PDA) Treatment Options

The Patent Ductus Arteriosus (PDA) treatment plan depends on your child’s age, symptoms, and the size of the opening.

1. Watchful Waiting: If the PDA is small and not causing problems, child heart doctors may simply monitor the baby. Some PDAs close on their own within the first year of life.
2. Medications: In premature infants, medicines may help the ductus close naturally. These drugs work by reducing chemicals that keep the ductus open.
3. Catheter-Based Closure: This is a minimally invasive procedure where a thin tube (catheter) is threaded through a blood vessel to the heart, and a small device is placed to close the PDA. It avoids open-heart surgery and usually has a faster recovery time.
4. Surgery: For larger PDAs or when medications and catheter closure aren’t suitable, open surgery may be required. A surgeon closes the ductus with clips or stitches.
5. Follow-Up: After PDA treatment, children often need follow-up visits with their doctor. Many go on to live active, normal lives once the PDA is closed.

When Is PDA Treatment Necessary?

Treatment for Patent Ductus Arteriosus (PDA) becomes necessary when the open blood vessel starts affecting the heart or lungs. A small PDA may not cause any symptoms and can sometimes close on its own, especially in full-term babies. In such cases, doctors may only recommend regular check-ups.

PDA treatment is usually required if the child shows symptoms like fast breathing, poor weight gain, frequent chest infections, or tiredness during feeding or physical activity. Treatment is also advised when tests show that the heart is working harder than normal or there is increased blood flow to the lungs.

In premature babies, early treatment may be needed to support breathing and prevent complications. For older children or adults, PDA treatment is important if the condition leads to heart enlargement, high blood pressure in the lungs, or repeated infections.

Today, Patent Ductus Arteriosus (PDA) Treatment in Kolkata offers safe and effective options, including medicines, catheter-based procedures, and surgery when required. Early treatment helps protect heart health and allows the child to grow and live a healthy, active life.

Conclusion

Patent Ductus Arteriosus (PDA) is a common congenital heart condition that can be safely treated when detected early. Understanding the causes, symptoms, and treatment options helps parents take timely action and avoid future complications. While some small PDAs may close on their own, others need medical or surgical care to protect the heart and lungs.

With proper diagnosis, modern treatment methods, and regular follow-up, most children with PDA can grow up healthy and active. Consulting an experienced pediatric heart specialist at the right time makes a big difference in outcomes. Early care, the right guidance, and ongoing support ensure the best possible heart health for children affected by Patent Ductus Arteriosus.
