It is the remnant of ductus arteriosus a blood vessel which bypassed the blood to the heart in foetus as the lungs are not functioning till the child is born. After birth once the lungs start functioning, it starts to close and is completely closed by second month.

What ligament holds the aorta?
The ligamentum arteriosum.
What are the foramen ovale and ligamentum arteriosum?
A foramen ovale is both a hole in the skull through which nerves pass and a fetal shunt between chambers of the heart. The ligamentum arteriosum is the connective tissue between the pulmonary artery and the aortic arch and is a closed vestige of a fetal duct known as the ductus arteriosus.
What do the ductus arteriosus and the foramen ovale become at birth?
Ligamentum arteriosum and the fossa ovalis. That is to say the arterial ligament and the oval depression (found in the left ventricle).
What exactly is Ligamentous Hypertrophy?
Hypertrophy of the ligaments in the vertebral canal of the spinal column can narrow the canal (stenosis) to the point that the spinal cord and/or nerve roots running through the canal are compressed. When the posterior longitudinal ligament in front and ligamentum flavum behind the spinal cord hypertrophy the cord is almost "circumferentially" surrounded and compressed.Hypertrophy of the ligamentum flavum laterally near the facet joint can also contribute to foraminal narrowing (stenosis) with potential nerve compression (pinching).Source(s):uscneurosurgerysearch.yahoo.com

What ligament holds the aorta?
The ligamentum arteriosum.
What structure is attached to pulmonary artery?
Ligamentum arteriosum
Where are the ligamentum arteriosum and the fossa ovalis located?
In the heart.
What is the ductus arteriosis called in adults?
Ligamentum Arteriosum
What is a fetal remnant associated with a healthy heart?
ligamentum arteriosum
What adaptive advantage is gained by the ductus arteriosus' closure at birth in a fetal pig?
The ductus arteriosus closes at birth in pigs and becomes the ligamentum arteriosum. This allows the pulmonary artery to function properly.
What were the ligamentum arteriosum and the fossa ovalis called in the fetal heart?
the fossa ovalis was the foramen ovale and the ligamentum arteriosum was the ductus arteriosus. They each contributed to shunting blood away from the non-functional lungs in the fetus.
What was the ligamentum arteriosum called in the fetal heart?
In the fetal heart it was called ductus arteriosis.
What is the difference between the foramen ovale and the ligamentum arteriosum?
The foramen ovale is the name given to the septal opening in the fetal heart which connects the two atria, whereas the ligamentum arteriosum is the remnants of the ductus arteriosus (which is the structure that connects the pulmonary trunk to the aorta in the fetus). The pressure in the lungs during the first breath, postnatally, causes blood to flow through the pulmonary artery and the ductus arteriosus regresses to a filled in tube, the ligamentum arteriosum.
What are the foramen ovale and ligamentum arteriosum?
A foramen ovale is both a hole in the skull through which nerves pass and a fetal shunt between chambers of the heart. The ligamentum arteriosum is the connective tissue between the pulmonary artery and the aortic arch and is a closed vestige of a fetal duct known as the ductus arteriosus.
Formen ovale Ductus arteriosus Ductus venosus what will these shunts become in a newborn?
The foramen ovale closes, becoming part of the interatrial septum. The Ductus arteriosus becomes the ligamentum arteriosum and the ductus venosus becomes the ligamentum venosum.
What do the ductus arteriosus and the foramen ovale become at birth?
Ligamentum arteriosum and the fossa ovalis. That is to say the arterial ligament and the oval depression (found in the left ventricle).
