Tricuspid Atresia

Galvan, 3rd Period

Identify the Problem

Tricuspid atresia is a heart defect present at birth (congenital) in which one of the valves (tricuspid valve) between two of the heart's chambers — the upper right chamber (right atrium) and the lower right chamber (right ventricle) — isn't formed. Instead, there's solid tissue between the chambers.

Who is most likely to get it

Tricuspid atresia occurs during fetal growth when your baby's heart is developing. While some factors, such as heredity or Down syndrome, may increase your baby's risk of congenital heart defects such as tricuspid atresia, the cause of congenital heart disease is unknown in most cases.

Describe the Symptoms

Additional Symtoms

  • Tiring easily, especially during feedings

  • Slow growth and poor weight gain

  • Fatigue and weakness

  • Shortness of breath

  • Sudden weight gain from fluid retention

How can it be diagnosed?

Echocardiogram - A test in which ultrasound is used to examine the heart.

Electrocardiogram - A test that checks for problems with the electrical activity of your heart.

Pulse oximetry - A test used to measure the oxygen level/saturation of the blood.

Chest X-ray - produces images of your heart, lungs, blood vessels, and many other things

Cardiac catheterization - a medical procedure used to diagnose and treat some heart conditions.

Treatment Methods

Tricuspid atresia is treated with multiple surgeries. Most babies with tricuspid atresia who have surgery may live well into adulthood, though follow-up surgeries are often needed.

Atrial septostomy.

Shunting.

Pulmonary artery band placement.

Glenn procedure.

Fontan procedure.

Prognosis

After birth a child can undergo 1st stage surgery called modified Blalock-Taussig (BT) and then heart surgery by the age of 3 to 6 months called a bidirectional Glenn. Between the ages of 2 and 5 years, the third surgery is called, Fontan procedure. Expected survival through all three stages of 75 percent to 95 percent depending on the exact malformations and surgery for any individual
