Is truncus arteriosus life threatening?

Untreated, truncus arteriosus can be fatal. Surgery to repair truncus arteriosus is generally successful, especially if the repair occurs before your baby is 1 month old.

How do you test for truncus arteriosus?

Diagnosis and Tests If an ultrasound indicates a potential problem, you may get a fetal echocardiogram. This type of ultrasound produces images of the baby’s heart. After your baby is born, a healthcare provider may use an echocardiogram to diagnose truncus arteriosus.

What type of blood is carried by 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.

What is the difference between truncus arteriosus and Conus arteriosus?

The caudal end of the bulbus cordis gives rise to the smooth parts (outflow tract) of the left and right ventricles (aortic vestibule & conus arteriosus respectively). The cranial end of the bulbus cordis (also known as the conus cordis) gives rise to the aorta and pulmonary trunk with the truncus arteriosus.

How long do people with truncus arteriosus live?

The actuarial survival rate was 97% at 10 years and 93% at 20 years, 30 years, and 40 years after the initial operation (Figure 1). Actuarial survival among hospital survivors after truncus arteriosus repair.

What are the characteristics of truncus arteriosus?

Truncus arteriosus (TA) is an uncommon congenital cardiovascular anomaly that is characterized by a single arterial trunk arising from the normally formed ventricles by means of a single semilunar valve (ie, truncal valve).

What is the survival rate of truncus arteriosus?

Over 90 percent of children survive repair of truncus arteriosus.

Is truncus arteriosus a heart disease?

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).

When is truncus arteriosus diagnosed?

Usually truncus arteriosus is diagnosed before the baby leaves the hospital if the doctor hears a murmur or sees a blue tint to the lips or skin.

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 & Symptoms Symptoms of truncus arteriosus include rapid breathing (tachypnea), lethargy, a bluish tint to the skin (cyanosis), poor feeding, difficulty breathing (dyspnea), and broadening of the fingertips (clubbing).
