Tricuspid Atresia: Causes, Symptoms, and Treatment

What kind of doctor treats Tricuspid Atresia?
A pediatric cardiologist, a doctor specializing in children's heart problems, treats tricuspid atresia. Heart surgeons perform the operations. A primary care doctor helps with everyday health and coordinates care with the heart team. Adults who had surgery as children need a cardiologist specializing in adult congenital heart disease.
What it is
Tricuspid atresia is a heart problem that babies are born with. The tricuspid valve is a door between two chambers of the heart. In tricuspid atresia, that door never formed. Babies with this condition need surgery in stages in the first few years of life.
Symptoms
Signs often appear in the first days or weeks of life, most commonly a bluish tint to the skin, lips, or nails, called cyanosis. Babies may breathe fast, tire easily during feeding, and gain weight slowly.
Causes and who gets it
Tricuspid atresia happens while the baby's heart is forming during pregnancy. Doctors do not know exactly why it happens. Some babies with heart defects have genetic conditions such as Down syndrome. Maternal diabetes or certain medicines may raise the risk.
How doctors diagnose it
Many cases are found before birth during a routine pregnancy ultrasound. After birth, doctors check the baby's color and oxygen levels. The main test is an echocardiogram, an ultrasound of the heart. Other tests include an electrocardiogram or chest X-ray.
Treatment
All babies with tricuspid atresia need surgery. Before surgery, a medicine may keep a natural blood vessel open so blood flows to the lungs. Surgeons usually perform a series of operations over the first two to four years of life to reroute blood to the lungs. Most will need follow-up heart care for life.
When to see a doctor
A newborn with a bluish color, trouble breathing, or poor feeding needs medical care right away. Call a doctor if a baby breathes fast, sweats during feeds, or is not gaining weight. Any sudden worsening of breathing or color is an emergency.
How a direct primary care or concierge doctor fits in
A direct primary care doctor is paid with a flat monthly fee instead of billing insurance for each visit. A concierge doctor works similarly but usually charges more. This kind of doctor can manage general health needs like checkups and vaccines and keep easy communication with the heart specialist. They cannot manage complex heart problems and would refer the patient to a cardiologist for heart-related care.
Common questions
Can tricuspid atresia be cured?
Surgery does not create a normal heart. But it can reroute blood so the body gets the oxygen it needs. Most people need lifelong checkups with a heart specialist. Outcomes differ from person to person.
Can it be found before birth?
Yes. Many cases are seen on a routine pregnancy ultrasound around the middle of pregnancy. Finding it early lets the medical team plan for care right after delivery.
Can children with tricuspid atresia be active?
Many children who have completed surgery can be active. Some may need to limit certain intense activities. The cardiologist gives guidance based on each person's heart. Parents should ask the heart team what is safe.
Will adults need more treatment?
Some people need additional procedures or medicines years after childhood surgery. Regular follow-up with a cardiologist who treats adult congenital heart disease helps find problems early. What each person needs depends on their own history.
