Congenital Anomalies of the Heart: Causes, Symptoms, and Treatment

What kind of doctor treats Congenital Anomalies of the Heart?
Heart defects are usually treated by a cardiologist, a doctor who specializes in the heart; children often see a pediatric cardiologist. Heart surgeons repair some defects. An ENT doctor does not treat the heart itself but may care for children with congenital heart problems who also have breathing, airway, or feeding issues.
What it is
Congenital anomalies of the heart are problems with the way the heart forms before a baby is born. If parts of the heart do not form the right way, the walls, valves, or blood vessels may be shaped differently than normal. Some problems are mild; others need treatment soon after birth.
Symptoms
Symptoms depend on the type of heart problem and how serious it is. Some babies have no symptoms at all. Others may have bluish lips or skin, fast breathing, poor feeding, tiredness, or slow weight gain. Older children may tire easily.
Causes and who gets it
Doctors do not always know why a heart defect happens. It often comes from changes in genes, sometimes passed down from parents. Exposures during pregnancy can also play a role, such as certain medicines, uncontrolled diabetes, alcohol, or rubella. These defects affect about 1 in 100 babies.
How doctors diagnose it
Many defects are found before birth with a fetal ultrasound. After birth, doctors may hear a heart murmur or notice symptoms. The main test is an echocardiogram, which uses sound waves to create a moving picture of the heart. Other tests include an electrocardiogram, chest X-ray, or pulse oximeter.
Treatment
Treatment depends on the type of defect and how severe it is. Some mild defects need only regular checkups. Others are treated with medicines or procedures. Cardiac catheterization uses a thin tube threaded through a blood vessel to repair some defects without open surgery. Serious defects may need surgery.
When to see a doctor
A baby or child should see a doctor quickly for bluish lips or skin, fast or hard breathing, or poor feeding with unusual sleepiness. Older children and adults should be seen for chest pain, fainting, or strong shortness of breath. Anyone treated for a heart defect with new symptoms should tell their doctor.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance; a concierge doctor usually charges more and often works alongside insurance. Either one can be a steady partner for these families, handling routine checkups and everyday needs. But they will refer the patient to a cardiologist or heart surgeon for testing and procedures.
Common questions
Can a congenital heart defect be cured?
Many defects can be repaired with surgery or a tube-based procedure. Some mild ones never need treatment. Many people need lifelong checkups with a heart specialist.
Can congenital heart defects be found before a baby is born?
Yes, often. A fetal ultrasound during pregnancy can show many heart problems. Some defects are not found until after birth or later in life.
Can adults have congenital heart problems?
Yes. Some defects cause no symptoms for years and are found in adulthood. Most children born with heart defects now live well into adulthood.
Do all heart murmurs mean a defect?
No. Many heart murmurs, extra sounds heard with a stethoscope, are harmless and common in children. A doctor may order an echocardiogram to be sure.
