Babies with a small hole in the heart often do not show any noticeable symptoms. In fact, many cases are only detected during a routine checkup.
Imagine a tiny baby who looks healthy on the outside but actually has an abnormality in the heart that cannot be seen with the naked eye. This condition often goes undetected at first and is only discovered after the baby has trouble feeding, struggles to gain weight, or turns bluish when crying. One condition that is fairly common in newborns is a hole in the heart, known in Indonesia as jantung bocor (“leaky heart”). Although it sounds frightening, this condition can be managed well if it is recognized early and properly treated.
Medically, the term hole in the heart in babies refers to a congenital abnormality in the structure of the heart that develops while the baby is still in the womb. In medicine, this condition is known as Congenital Heart Disease (CHD), which occurs when there is a gap or hole in the heart’s dividing wall, either between the upper chambers (Atrial Septal Defect / ASD) or between the lower chambers (Ventricular Septal Defect / VSD), or when a connection between the large blood vessels has not fully closed, as in Patent Ductus Arteriosus (PDA).
According to data from Children’s HeartLink, about 1 in 100 babies born worldwide has a congenital heart defect. In Indonesia, the incidence of CHD is estimated to reach 8 per 1,000 live births, making a hole in the heart one of the most frequently found types of congenital abnormality in babies.
What Is a Hole in the Heart in Babies?
A hole in the heart in babies is a lay term for an abnormal hole or gap inside the baby’s heart that should have closed tightly by birth. This condition falls under Congenital Heart Disease (CHD), which refers to structural heart abnormalities that are already present while the baby is still in the womb.
Normally, the human heart has four chambers separated by dividing walls: two upper chambers (atria) and two lower chambers (ventricles). If there is a hole in this dividing wall, blood from the left and right sides of the heart can mix. As a result, the heart has to work harder because it must pump more blood, and this can affect the oxygen supply to the baby’s whole body.
According to the Centers for Disease Control and Prevention (CDC), CHD is the most common type of birth defect and affects about 40,000 babies each year in the United States. In Indonesia, based on data from the Indonesian Ministry of Health (Kemenkes), the incidence of CHD is estimated to reach 30,000 new cases per year, and many of them are cases of a hole in the heart.
Common Types of Holes in the Heart in Babies
There are several types of holes in the heart that are most often found in babies, including:
1. Atrial Septal Defect (ASD), a Hole in the Wall Between the Upper Chambers
ASD occurs when there is a hole between the two upper chambers of the heart (the right and left atria). Normally, these two atria are not connected to each other, but with ASD, oxygen-rich blood from the left atrium flows back into the right atrium. This leak can increase blood flow to the lungs and cause the baby to breathe fast or tire easily. The hole can be small (and close on its own as the baby grows) or large enough to require medical intervention.
2. Ventricular Septal Defect (VSD), a Hole in the Wall Between the Lower Chambers
VSD is the most common type of hole in the heart. This hole is located between the two lower chambers of the heart (the right and left ventricles). Similar to ASD, oxygen-rich blood from the left side can flow back into the right side and on to the lungs. If the hole is large enough, this condition can cause the heart to enlarge and lead to symptoms such as difficulty feeding, growth problems, or shortness of breath.
3. Patent Ductus Arteriosus (PDA), a Channel That Does Not Close
PDA occurs when the ductus arteriosus, a natural channel that connects the pulmonary artery and the aorta during fetal life, fails to close after the baby is born. This channel is actually only needed while the baby is in the womb and should close naturally within the first few days after birth. If it stays open, blood from the aorta can flow back to the lungs, causing fluid overload in the lungs and increasing the heart’s workload.
In addition to the three types above, there are also complex forms of CHD such as Tetralogy of Fallot or Transposition of the Great Arteries, which require more intensive treatment. However, these cases are rarer.
Causes of a Hole in the Heart in Babies
A hole in the heart, or congenital heart disease (CHD), develops while the baby is still in the womb. Although not all causes can be explained with certainty, various studies and medical data show that this condition is influenced by a combination of genetic factors, the environment, and the mother’s health during pregnancy. Here are some common causes of a hole in the heart in babies:
1. Genetic Factors
One of the main causes of a hole in the heart in babies is heredity. If there is a family history of congenital heart disease, whether on the father’s side, the mother’s side, or among siblings, the baby’s risk of a heart abnormality also increases.
A study from the American Heart Association (AHA) shows that a child’s chance of having a heart abnormality increases 3 to 5 times if a close family member has a history of CHD. This abnormality can be inherited in the form of certain gene mutations that affect how the heart’s structure forms during pregnancy.
Note: Genetic testing can be a preventive step for couples with a family history of CHD to find out their risk early.
2. Chromosomal Abnormalities (Such as Down Syndrome)
Chromosomal abnormalities in babies are also closely linked to a hole in the heart. One of the most common is Down syndrome, a genetic condition caused by an extra copy of chromosome 21 (trisomy 21).
According to data from the Centers for Disease Control and Prevention (CDC), about 50% to 65% of babies with Down syndrome have congenital heart disease, including a hole in the heart. A type of abnormality often found is Atrioventricular Septal Defect (AVSD), a combination of holes between the atria and the ventricles.
Conclusion: Regular prenatal checkups are very important to detect possible chromosomal abnormalities as early as possible.
3. Infections During Pregnancy
Certain infections in pregnant women can disrupt the development of the baby’s vital organs, including the heart. One of the most widely known infectious causes of CHD is rubella (German measles) infection in the first trimester of pregnancy.
Untreated rubella can cause congenital rubella syndrome in the baby, which includes problems with the heart, vision, and hearing. In addition, mothers with uncontrolled gestational diabetes also have a higher risk of giving birth to a baby with a hole in the heart.
WHO data states that rubella infection during pregnancy accounts for most cases of congenital rubella syndrome in developing countries, including congenital heart abnormalities. Vaccination before pregnancy and blood sugar control during pregnancy are very important to prevent this risk.
4. Exposure to Harmful Substances (Cigarettes, Alcohol, Certain Medications)
Exposure to harmful substances during pregnancy greatly affects the baby’s development, especially vital organs such as the heart. Pregnant women who smoke, drink alcohol, or use certain medications without a doctor’s supervision are at high risk of giving birth to a baby with a heart abnormality.
- Cigarettes contain nicotine and carbon monoxide, which can disrupt the oxygen supply to the baby.
- Alcohol can cause fetal alcohol syndrome, which is also linked to structural heart abnormalities.
- Certain medications such as isotretinoin (for severe acne) and anti-seizure medications can have harmful effects if taken without medical supervision.
5. Environmental Factors
The environment where a pregnant woman lives and her living conditions can also trigger congenital heart abnormalities. Some environmental factors that can potentially cause a hole in the heart in babies include:
- Exposure to harmful chemicals such as pesticides, heavy metals, or industrial solvents.
- Air pollution and poor air quality where you live.
- The mother’s nutrition during pregnancy, including a lack of folic acid, which is needed for the development of the baby’s nervous system and organs.
According to a report in Environmental Health Perspectives, exposure to heavy air pollution during the first trimester of pregnancy can increase the risk of congenital heart defects by up to 20% to 30%.
Preventive steps: Maintaining a healthy lifestyle, eating a balanced diet, and avoiding exposure to harmful chemicals can be practical steps to prevent this risk.
Although not all causes of a hole in the heart in babies can be prevented, many risk factors can be controlled through careful pregnancy planning, regular checkups, and a healthy lifestyle during pregnancy. We hope this understanding helps parents stay more alert and ready to take the right steps for their little one’s health.
Symptoms of a Hole in the Heart in Babies
The symptoms of a hole in the heart in babies can vary widely, depending on the size of the hole and how much it affects blood circulation. Some babies with a mild abnormality may look healthy and show no clear signs. However, in more serious cases, the symptoms can interfere with the baby’s growth, development, and overall health.
Here are the common symptoms that parents should recognize:
1. Mild Symptoms (Small Defect)
Babies with a small hole in the heart often do not show any noticeable symptoms. In fact, many cases are only detected during a routine checkup.
Mild symptoms include:
- Heart murmur: An abnormal heart sound that a doctor can only hear through a stethoscope. This murmur can be an early sign of a small hole in the heart.
- Normal growth and activity: The baby usually shows no problems with feeding, breathing, growth, or development.
Note: Even if the baby looks healthy, a baby with a heart murmur still needs further evaluation by a pediatric cardiologist to confirm the condition.
2. Serious Symptoms (Large Defect)
If the hole in the heart is large enough, the heart has to work harder and the body’s oxygen supply can be disrupted. This can trigger a range of more serious symptoms, such as:
- Fast or labored breathing, even when the baby is not active.
- Difficulty feeding or tiring quickly while feeding. The baby often feeds only briefly and then stops because of being out of breath.
- Difficulty gaining weight even though nutritional intake is adequate.
- Bluish lips, tongue, or nails (cyanosis), especially when crying, feeding, or being active.
- The baby looks weak or is unusually fussy for no clear reason.
- Excessive sweating, even when the baby is not feeling hot or has only been feeding for a short time.
According to data from the American Academy of Pediatrics (AAP), more than 50% of babies with significant congenital heart defects experience growth problems because their bodies work harder to breathe and pump blood.
3. When Should You Take Your Baby to a Doctor Right Away?
Parents are advised to consult a doctor promptly if they notice the following signs:
- The baby looks bluish, especially on the lips and nails, which indicates a lack of oxygen.
- The baby has fast, shallow, and labored breathing.
- Difficulty eating or feeding, and appears extremely tired.
- Weight does not increase or even decreases.
- The baby becomes limp, unresponsive, or cries constantly.
These symptoms may look like other mild conditions, but in babies, even small changes can be a sign of a serious problem such as a hole in the heart.
Recognizing the symptoms of a hole in the heart early is the key to prompt and appropriate treatment. The earlier this condition is detected, the greater the baby’s chance of getting effective care and growing up healthy. That is why routine checkups and parents’ alertness play a very important role in detecting this abnormality.
Diagnosing a Hole in the Heart in Babies
Finding out that your baby has a hole in the heart can certainly be an anxious experience. However, with advances in medical technology and the expertise of cardiologists, a hole in the heart can be diagnosed accurately and relatively quickly. This process is very important for determining the type, the severity, and the most appropriate treatment steps.
1. Physical Examination by a Pediatrician or Pediatric Cardiologist
The first step in diagnosing a hole in the heart usually starts with a routine physical examination. The doctor will evaluate several early signs, such as:
- The color of the skin, lips, and nails (to detect possible cyanosis)
- The baby’s breathing pattern
- Weight gain and feeding ability
One of the most common findings is a heart murmur, an unusual whooshing sound as blood flows through the heart. Although not every murmur means a hole in the heart, it is often an early clue that further tests are needed.
2. Detection Through Abnormal Heart Sounds (Murmurs)
A heart murmur is usually detected with a stethoscope during a baby’s routine checkup. This sound occurs because of abnormal blood flow caused by a hole in the heart’s dividing wall. A murmur can be:
- Functional (normal): harmless and will go away over time.
- Pathological (abnormal): can be a sign of a structural abnormality such as an Atrial Septal Defect (ASD) or a Ventricular Septal Defect (VSD).
If the doctor suspects a pathological murmur, the baby will be referred to a pediatric heart specialist (pediatric cardiologist) for a more thorough examination.
3. Further Tests to Confirm the Diagnosis
Once a hole in the heart is suspected, the doctor will recommend a series of more detailed tests:
- Echocardiography (heart ultrasound): This is the main test for detecting a hole in the heart in babies. Using sound waves (ultrasound), the doctor can see the structure of the heart directly, including the size of the hole, the direction of blood flow, and how the heart valves and ventricles work. An advantage of echocardiography is that the test does not hurt and is safe, and it can even be done right after birth or while the baby is still in the womb (fetal echo).
- Chest X-ray: Used to see the size and shape of the heart, and to find out whether fluid has built up in the lungs, which can happen because of a congenital heart abnormality.
- Electrocardiogram (ECG): This test records the heart’s electrical activity and can help the doctor assess the heart’s rhythm and workload.
- Cardiac CT scan or cardiac MRI: If needed, especially for complex cases, the doctor may recommend further imaging with a CT scan or MRI to get a more detailed picture of the heart’s structure.
For this reason, echocardiography is strongly recommended when a hole in the heart is suspected.
4. Detection Before Birth (Fetal Echocardiography)
If the mother has certain risk factors such as a family history of CHD, rubella infection, or gestational diabetes, the obstetrician may recommend a fetal heart ultrasound (fetal echo) from 18 to 24 weeks of pregnancy. This test can help detect heart abnormalities early and prepare for treatment right after the baby is born.
A hole in the heart in babies can now be diagnosed quickly, accurately, and safely thanks to advances in medical technology. Early examination is very important so that the baby can receive appropriate care promptly and have the chance to survive, grow, and develop optimally. If you suspect a problem with your baby’s heart, do not hesitate to consult a cardiologist.
Can a Hole in the Heart Heal?
The question parents ask most often when they hear a diagnosis of a hole in the heart in their baby is: “Can it heal?” The good news is that many cases of a hole in the heart in babies can improve over time, even without surgery. Of course, this depends on the type and size of the hole, as well as how the baby’s body responds to the condition.
Possibility of Spontaneous Closure
Some types of holes in the heart, especially small ones, can close on their own as the baby grows. This usually happens with:
- Ventricular Septal Defect (VSD) that is small
- Atrial Septal Defect (ASD) that is small
- Patent Ductus Arteriosus (PDA) in newborns
This closure can happen naturally within a few months up to the child’s first year of life. That is why routine monitoring by a doctor is very important to make sure the condition does not cause serious complications.
When Is Medical Intervention Needed?
If the hole in the heart is large enough or causes disruptive symptoms, active medical treatment is needed. Conditions that require intervention include:
- The baby has difficulty breathing or feeding
- Weight does not increase
- Growth and development are impaired
- Increased blood pressure in the lungs is found (pulmonary hypertension)
- A high risk of heart infection (endocarditis)
In cases like these, the doctor will consider treatment or medical procedures, such as heart medications, catheterization, or even open-heart surgery.
The Role of Routine Monitoring and Follow-Up by a Pediatric Cardiologist
Every baby with a congenital heart abnormality, no matter how small, should be monitored regularly by a pediatric cardiologist. The goals of this monitoring are to:
- Track how the heart condition develops over time through echocardiography
- Assess the need for medical intervention if the condition worsens
- Make sure the child’s growth and development are on track
The frequency of follow-up visits can vary, from every month to every 6 months, depending on each child’s condition.
A hole in the heart in babies does not mean it cannot heal. Many children with a small hole can grow up healthy without needing surgery. However, for larger holes, medical intervention can be one of the treatment options, depending on the child’s condition. What matters most is early detection, close monitoring, and support from the medical team.
Care and Treatment of a Hole in the Heart in Babies
Once the diagnosis is confirmed, the next main concern for parents is: how is it treated? The good news is that the various forms of a hole in the heart in babies can now be managed with an approach tailored to each child’s condition. Treatment depends greatly on the type and size of the hole, and on whether the condition causes symptoms.
Treatment of a Mild Hole in the Heart (Small Defect)
In many cases, especially if the hole is small and does not significantly affect how the heart works, the doctor will choose routine monitoring without invasive medical procedures.
- Regular monitoring
- The pediatric cardiologist will perform regular tests, such as echocardiography, to monitor whether the hole closes naturally.
- Follow-up visits may be scheduled every 3 to 6 months, depending on the baby’s condition.
- Parents will be given guidance on the warning signs to watch for at home.
- Lifestyle and nutrition
- Parents are advised to make sure the baby gets good nutrition and enough rest.
- Babies with a small defect usually do not need any special activity restrictions, but they still need monitoring so that their growth and development are on track.
According to Cleveland Clinic, more than 40% of small ASD and VSD cases can close on their own within the first 1 to 2 years of a child’s life.
Treatment of a Moderate to Severe Hole in the Heart (Large Defect)
If the hole is large enough to affect how the heart or lungs work, the doctor will recommend medical intervention, either medication or a procedure.
- Medication
- Medications are given to relieve symptoms and support heart function.
- Examples of commonly used medications:
- Diuretics, to reduce excess fluid in the body
- Heart-strengthening medications, such as digoxin, to help the heart pump more effectively
- Medications are usually given on an individual basis, according to the baby’s condition and age.
- Medical procedure: cardiac catheterization
- This is a minimally invasive procedure performed without opening the chest.
- The doctor inserts a small device through a blood vessel to the heart, then places a special closure (device closure) over the hole.
- Suitable for certain types of holes, such as ASD or PDA.
- This procedure is usually done in a cath lab under general anesthesia, and recovery time is relatively short.
- Open-heart surgery
- Needed if the hole is very large, the abnormality is complex, or catheterization is not possible.
- Surgery is performed by a pediatric heart surgery team (pediatric cardiac surgeon) with the support of perfusion equipment (a heart-lung machine).
- After surgery, the baby will be cared for in the ICCU (Intensive Cardiac Care Unit) for intensive monitoring.
Recovery and Follow-Up
- After the procedure, the baby will be closely monitored to make sure there are no further complications.
- The doctor will schedule routine follow-up visits and provide guidance on appropriate nutrition and activity.
- In many cases, babies who receive optimal care can grow and develop like other healthy children.
Treating a hole in the heart in babies does not have to be frightening. With careful monitoring and appropriate medical intervention, many children with CHD can live healthy, active lives and grow like other children. The keys are early diagnosis, access to a pediatric cardiologist, and the support of adequate health facilities.
Complications If Left Untreated
Although the term “hole in the heart” may sound mild in some cases, it does not mean it can be taken lightly. If it is not treated properly and on time, a hole in a baby’s heart can cause various serious complications with long-term effects on the child’s health and quality of life.
Here are some of the main complications that can occur if this condition is left without medical treatment:
1. Congestive Heart Failure
A baby’s heart with a hole, especially a large one, has to work harder than usual to pump blood. Over time, the heart muscle can weaken, become unable to meet the body’s needs, and lead to congestive heart failure.
Symptoms may include:
- Fast and labored breathing
- The baby tires easily while feeding
- A swollen belly due to fluid buildup
- Swelling in the legs or arms (rare, but possible)
Data from the Children’s Heart Foundation states that children with untreated congenital heart abnormalities have a higher risk of developing heart failure at an early age.
2. Pulmonary Hypertension (High Blood Pressure in the Lungs)
A hole in the heart causes too much blood to flow to the lungs. If this continues, the pressure in the lung blood vessels rises and leads to a condition called pulmonary hypertension.
In the long term, this can cause:
- Permanent lung damage
- A weakened right side of the heart
- An increased risk of death
You need to be alert because pulmonary hypertension can cause permanent damage. Early examination and prompt treatment greatly affect the outcome.
3. Growth and Developmental Problems
Babies with a hole in the heart often have difficulty feeding and eating, so their nutritional intake is not enough. In addition, the heavy workload on the heart makes the baby tire quickly, even from simple activities such as crying or moving.
As a result:
- Difficulty gaining weight (failure to thrive)
- Height that does not follow the growth curve
- Delayed motor development (such as sitting, crawling, and standing)
Studies from the World Health Organization (WHO) show that children with chronic diseases such as congenital heart abnormalities have a high risk of malnutrition and delayed growth and development.
4. Risk of Heart Infection (Infective Endocarditis)
A hole in the heart creates ideal conditions for germs to attach and grow, especially if there is an infection in another part of the body (for example, the teeth or the respiratory tract). This can cause infective endocarditis, a serious infection of the inner lining of the heart and its valves.
Typical signs of endocarditis in children include:
- A fever that does not go away
- Loss of appetite
- An abnormal heartbeat
- Signs of heart failure that appear suddenly
This condition is very dangerous and requires intensive treatment with high-dose antibiotics, and sometimes even surgery.
A hole in the heart in babies should not be left untreated, even if the symptoms seem mild. If left untreated, it can trigger dangerous complications with permanent effects on the child’s health. That is why it is important for parents to:
- Consult a doctor promptly if there are any worrying symptoms
- Attend routine checkups as advised by the doctor
- Make sure the child receives appropriate treatment from the medical team
