What is the difference between truncus arteriosus and Conus arteriosus?

What is the difference between truncus arteriosus and Conus arteriosus?

The truncus arteriosus and bulbus cordis are divided by the aorticopulmonary septum. The truncus arteriosus gives rise to the ascending aorta and the pulmonary trunk. 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.

What are the different types of truncus arteriosus?

There are 4 types of truncus arteriosus (types I, II, III and IV). The type depends on where the pulmonary arteries are and whether they formed as a single artery or several arteries. This is a normal heart.

What are the symptoms of truncus arteriosus?

Infants with truncus arteriosus or other conditions causing cyanosis can have symptoms such as:

• Problems breathing.
• Pounding heart.
• Weak pulse.
• Ashen or bluish skin color.
• Poor feeding.
• Extreme sleepiness.

How do you fix truncus arteriosus?

The surgical repair of truncus arteriosus requires the use of heart-lung bypass machine support. It involves three major components: Separating the pulmonary arteries from the main truncus (the truncus will remain as the first part of the aorta) Closure of the ventricular septal defect using a patch.

How is truncus arteriosus treated?

Truncus arteriosus is treated with surgery to repair the heart defect. Surgery is usually performed in the neonatal period (1-2 weeks after birth). During the surgery, the ventricular septal defect (hole in the wall between the right and left ventricles) is closed with a patch.

Can truncus arteriosus be cured?

Truncus arteriosus is a serious condition. Unless it is treated, it usually results in death within the first year of life. Truncus arteriosus is treated with surgery, which is often successful, especially if it is performed before the infant is two months old.

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.

Can you live with truncus arteriosus?

Key points about truncus arteriosus The low levels of oxygen may not be enough to meet the body’s needs and sustain life. Truncus arteriosus must be treated with surgery. Most children who have had truncus arteriosus surgical repair will live healthy lives.

How serious is truncus arteriosus?

As a result of truncus arteriosus, oxygen-poor blood that should go to the lungs and oxygen-rich blood that should go to the rest of the body are mixed. This creates severe circulatory problems. Untreated, truncus arteriosus can be fatal.

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.

What does truncus arteriosus mean in medical terms?

Truncus arteriosus (TRUNG-kus ahr-teer-e-O-sus) is a rare heart defect that’s present at birth (congenital). 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.

What are the side effects of truncus arteriosus surgery?

Even with successful surgical repair of the heart during infancy, other complications associated with truncus arteriosus may occur later in life: 1 Progressive pulmonary hypertension. 2 Leaky heart valves (regurgitation). 3 Heart rhythm disturbances (arrhythmias). 4 Problems related to prior operation.

Where does truncus arteriosus exit the fetal heart?

The left ventricle, the lower left chamber, pumps the oxygen-rich blood through a large vessel called the aorta and on to the rest of the body. The formation of the fetal heart is complex. At a certain point, all babies have a single large vessel (truncus arteriosus) exiting the heart.

Can a person with truncus arteriosus live into adulthood?

In rare cases, a person with truncus arteriosus can survive infancy without surgical repair of the heart and live into adulthood. However, people with this condition will almost certainly develop heart failure and pulmonary hypertension (Eisenmenger syndrome).
