Congenital heart disease (CHD) affects children and families around the world, yet many people know little about it until it becomes part of their own lives.

CHD refers to structural differences in the heart that are present at birth. These conditions can affect the heart chambers, valves, major blood vessels, or the way blood moves through the heart and body. Some are mild and require little or no intervention. Others are complex and may require surgery, catheter-based procedures, medications, or lifelong specialized care.

Greater congenital heart disease awareness matters because every diagnosis represents more than a medical condition. It represents a child, a family, and a journey that may include uncertainty, difficult decisions, resilience, and hope.

Understanding CHD is one way to better support the children and families living with it.

What Is Congenital Heart Disease?

Congenital heart disease develops before birth, while the heart is forming.

The term includes many different structural abnormalities. Some affect the walls separating the chambers of the heart. Others involve the heart valves, the major blood vessels connected to the heart, or several structures at the same time.

Some congenital heart defects are detected during pregnancy or shortly after birth. Others may not become apparent until later in infancy, childhood, or even adulthood.

CHD is not one single disease with one predictable course. Two children may both have congenital heart disease and yet have very different diagnoses, treatment plans, and long-term outcomes.

That diversity is important to remember when talking about CHD. Each child’s experience is unique.

How Common Is Congenital Heart Disease?

Congenital heart defects are among the most common birth defects.

In the United States, they affect approximately 1% of births, representing tens of thousands of babies each year.

For a family hearing the diagnosis for the first time, statistics may offer little comfort. But they do provide an important reminder: congenital heart disease is not rare, and many families are navigating similar questions, fears, and hopes.

Medical progress has also changed the outlook for many children with CHD. Advances in prenatal diagnosis, surgery, cardiac catheterization, intensive care, medications, imaging, and long-term follow-up have significantly improved survival and quality of life.

Today, more children with congenital heart disease are growing into adulthood than ever before.

What Causes Congenital Heart Disease?

One of the first questions families may ask after a diagnosis is, “Why did this happen?”

In many cases, there is no single clear answer.

Some congenital heart defects are associated with genetic or chromosomal differences. Certain maternal health conditions, medications, infections, and environmental exposures may also influence risk.

However, for many children, no specific cause is ever identified.

This uncertainty can be difficult for families, especially when parents begin wondering whether they somehow caused the condition. In most cases, congenital heart disease is not preventable and cannot be traced to one particular action or decision during pregnancy.

Common Types of Congenital Heart Defects

CHD includes a wide range of conditions, from relatively simple structural differences to highly complex abnormalities.

Some examples include:

• Atrial septal defect (ASD): an opening between the heart’s two upper chambers.
• Ventricular septal defect (VSD): an opening between the heart’s two lower chambers.
• Patent ductus arteriosus (PDA): persistence after birth of a blood vessel that normally closes shortly after delivery.
• Pulmonary valve stenosis: narrowing at the pulmonary valve that can restrict blood flow from the heart to the lungs.
• Coarctation of the aorta: narrowing of part of the aorta, the major artery that carries blood from the heart to the body.
• Tetralogy of Fallot: a combination of structural abnormalities that alters blood flow through the heart.
• Transposition of the great arteries: a condition in which the two major arteries leaving the heart are connected differently than usual.
• Hypoplastic left heart syndrome: a complex condition in which structures on the left side of the heart are severely underdeveloped.

These conditions vary considerably in severity. Some may require only monitoring, while others require intervention early in life.

How Is Congenital Heart Disease Detected?

CHD can be diagnosed at different stages.

Some heart defects are identified before birth through prenatal ultrasound and, when indicated, fetal echocardiography. Detecting a significant heart condition before delivery can give families and medical teams time to prepare for specialized care immediately after birth.

After birth, CHD may be suspected because of findings on physical examination, such as an abnormal heart sound, low oxygen levels, or other signs of altered circulation.

Newborn pulse oximetry screening can also help identify certain critical congenital heart defects by measuring oxygen saturation.

However, not every congenital heart defect is detected during pregnancy or the newborn period. Some become apparent later when symptoms develop or during routine medical examinations.

Signs and Symptoms of Congenital Heart Disease

Symptoms vary depending on the type and severity of the defect.

In babies, possible signs of significant CHD may include:

• rapid or difficult breathing
• difficulty feeding
• tiring or sweating during feeds
• poor weight gain
• bluish or gray discoloration of the lips, tongue, or skin
• unusual sleepiness or decreased activity

Older children may experience unusual fatigue, shortness of breath with activity, fainting, or difficulty keeping up with peers.

These symptoms are not unique to congenital heart disease and can occur for many other reasons. Concerning symptoms should therefore be evaluated by a healthcare professional rather than interpreted in isolation.

Severe breathing difficulty, fainting, or blue or gray discoloration can require urgent medical evaluation.

How Is Congenital Heart Disease Treated?

Treatment depends on the specific heart defect and its severity.

Some children require only periodic monitoring. Others may need medications, catheter-based procedures, surgery, or a combination of treatments.

Advances in cardiac catheterization have made it possible to treat certain defects without open-heart surgery. For more complex conditions, one or more operations may be necessary to repair the heart or improve circulation.

For some children, treatment occurs primarily during infancy or childhood. For others, congenital heart disease remains an important part of medical care throughout life.

Successful treatment does not always mean that follow-up is no longer necessary. Even after childhood procedures have gone well, some individuals require continued monitoring by clinicians experienced in congenital heart disease.

Children With CHD Grow Up

One of the most encouraging developments in congenital heart care is that more children are surviving into adulthood.

This progress represents decades of advances in pediatric cardiology, cardiac surgery, intensive care, and long-term management.

It also means that congenital heart disease awareness must extend beyond childhood.

Adults born with CHD may need ongoing monitoring for concerns involving heart rhythm, heart function, valves, previous surgical repairs, exercise tolerance, pregnancy, or other cardiovascular issues.

Helping adolescents transition from pediatric care to appropriate adult congenital heart care can therefore be an important part of protecting long-term health.

Congenital heart disease may begin before birth, but for many people, it is a lifelong journey.

The Impact of CHD Goes Beyond the Heart

The effects of congenital heart disease are not limited to anatomy, tests, or procedures.

Families may face prenatal uncertainty, neonatal intensive care, repeated hospitalizations, surgeries, medications, frequent appointments, missed work or school, financial strain, and the emotional weight of wondering what the future may hold.

Children may experience procedures, scars, activity restrictions, anxiety surrounding medical care, or the feeling that their childhood is different from that of their peers.

Parents and caregivers may carry fear and responsibility that others do not always see. Siblings may also be affected by changes in routines, time away from home, or the emotional demands of a family member’s illness.

Supporting a child with CHD therefore means recognizing the needs of the whole family, not simply treating the heart.

Why Congenital Heart Disease Awareness Matters

Awareness matters because understanding can change the way people respond.

It helps others recognize that congenital heart disease is relatively common, even when an affected child appears completely healthy from the outside.

It highlights the importance of early diagnosis, specialized treatment, continued research, and appropriate long-term follow-up.

It also gives greater visibility to the experiences of children, adults, parents, siblings, and caregivers living with CHD.

Greater awareness can encourage support for children’s hospitals, research programs, family resources, and charitable organizations working to improve outcomes for children with heart disease.

Awareness alone cannot eliminate the challenges of CHD.

But awareness can lead to understanding.

Understanding can lead to compassion.

And compassion can inspire meaningful action.

How Pendants for a Cause Supports Children in Need

Supporting children facing serious medical conditions has been part of the mission behind Pendants for a Cause from its earliest days.

What began in 2019 as a small effort to turn handmade sea glass jewelry into support for people in need gradually grew into a broader mission centered on compassion. Among the causes supported through this work have been efforts to help fund life-saving heart surgery for children.

Today, Ocean of Hope Jewelry serves as the creative expression of that mission.

Through Pendants for a Cause, proceeds from purchases are donated to pediatric medical charities that support children and families facing serious health challenges.

The idea behind the mission has always been simple: something beautiful can also become an opportunity to help someone else.

A single pendant may be small. But when small acts of generosity are repeated, their impact can extend far beyond the object itself.

How You Can Help Raise Congenital Heart Disease Awareness

Helping does not always require a large gesture.

Learning about congenital heart disease is an important first step. Sharing accurate information can help others better understand CHD and the realities affected families may face.

Supporting reputable pediatric medical charities, congenital heart disease research, children’s hospitals, and family-support programs can help turn awareness into action.

It is equally important to listen to the people living with CHD.

Every family’s story is different. Giving children, adults, parents, siblings, and caregivers space to share their experiences in their own words is one of the most meaningful forms of awareness.

Compassion begins with understanding, and understanding often begins with listening.

Hope for Every Heart

Congenital heart disease can change the course of a child’s life and the lives of everyone who loves that child.

But the story of CHD is also a story of remarkable progress.

Children born with heart conditions that were once extraordinarily difficult to treat now have possibilities that did not exist generations ago. Researchers continue to expand knowledge. Medical teams continue to refine treatment. Families continue to advocate, persevere, and hope.

There is still much work to be done.

More research is needed. Access to specialized care remains essential. Families continue to need practical and emotional support. Children and adults living with CHD deserve to be understood, supported, and seen.

By increasing congenital heart disease awareness, supporting continued research and care, and standing beside the families affected by CHD, each of us can help carry that progress forward.

Every child deserves the opportunity for a healthier future.

And every heart deserves hope.
