Where is the truncus arteriosus?

Truncus arteriosus is a rare type of heart disease in which a single blood vessel (truncus arteriosus) comes out of the right and left ventricles, instead of the normal 2 vessels (pulmonary artery and aorta). It is present at birth (congenital heart disease).

What are the causes of truncus arteriosus?

Truncus arteriosus occurs when your baby’s heart is developing in the womb, and is, therefore, present at birth (congenital). In most cases the cause is unknown.

What is the most common type of truncus arteriosus?

Type I/A1 is the most common form, found in ~60% of patients with Truncus Arteriosus. Surgical repair is required due to likely development of congestive heart failure.

What are the signs and symptoms of truncus arteriosus?

Signs and symptoms of truncus arteriosus

  • Blue or purple tint to lips, skin and nails (cyanosis)
  • Poor eating and poor weight gain.
  • Rapid breathing or shortness of breath.
  • Profuse sweating, especially with feeding.
  • More sleepiness than normal.
  • Unresponsiveness (the baby seems “out of it”)

What is the function of truncus arteriosus?

The left side of the heart pumps oxygen-rich blood through the aorta to the rest of the body. In babies with a truncus arteriosus, oxygen-poor blood and oxygen-rich blood are mixed together as blood flows to the lungs and the rest of the body.

How long can you live with truncus arteriosus?

Results: The median age at follow-up was 23.6 years (range, 12.4 to 44.5 years). The median follow-up duration was 23.4 years (range, 12.3 to 40.7 years). The actuarial survival rate was 97% at 10 years and 93% at both 20 years and 40 years after the initial operation.

Is truncus arteriosus genetic?

The exact cause of truncus arteriosus is not known. It has been suggested that some cases may develop due to the interaction of many genetic and environmental factors (multifactorial inheritance). The malformation is the result of an error in embryonic development.

Is truncus arteriosus curable?

There are several procedures to correct truncus arteriosus. The most common procedure is called a Rastelli repair. The surgery involves: Using a patch to close the VSD, or hole in the heart.

Is truncus arteriosus life threatening?

A baby with truncus arteriosus has one large artery (instead of the usual two arteries) for blood to flow in and out of the heart. These babies also have a single truncal valve instead of two valves to control this blood flow. Truncus arteriosus is a life-threatening condition. It requires surgery shortly after birth.

Is there a cure for truncus arteriosus?

Infants with truncus arteriosus must have surgery. Multiple procedures or surgeries might be necessary, especially as your child grows. Medications might be given before surgery to help improve heart health.

What does truncus arteriosus mean in babies?

If you or your baby has truncus arteriosus, it means that one large blood vessel leads out of the heart. Normally, there are two separate vessels coming out of the heart. In addition, there is usually a hole — known as a ventricular septal defect — between the two lower chambers of the heart.

What is truncus arteriosus (Trung)?

Truncus arteriosus pronounced TRUNG-kus ahr-teer-e-O-sus), also known as common truncus, is a rare defect of the heart in which a single common blood vessel comes out of the heart, instead of the usual two vessels (the main pulmonary artery and aorta). What is Truncus Arteriosus. Truncus arteriosus is a birth defect of the heart.

How does truncus arteriosus affect the heart?

As a result, too much blood goes to the lungs and the heart works harder to pump blood to the rest of the body. Also, instead of having both an aortic valve and a pulmonary valve, babies with truncus arteriosus have a single common valve (truncal valve) controlling blood flow out of the heart. The truncal valve is often abnormal.

Is truncus arteriosus a CCHD?

What is Truncus Arteriosus. re is also usually a hole between the bottom two chambers of the heart (ventricles) called a ventricular septal defect. Because a baby with this defect may need surgery or other procedures soon after birth, truncus arteriosus is considered a critical congenital heart defect (CCHD).
