2024年11月21日 · Truncus arteriosus (TRUNG-kus ahr-teer-e-O-sus) is a rare heart condition present at birth. That means it's a congenital heart defect. In this condition, one large blood vessel leads out of the heart, instead of two.

Truncus arteriosus occurs when the two large arteries carrying blood away from the heart don’t form properly and one large artery is present instead. This artery (the truncus) sits over a large opening or hole in the wall between the two pumping chambers (ventricular septal defect).

Truncus arteriosus is a rare congenital heart defect that affects how blood flows out of your baby’s heart. Instead of a separate pulmonary artery and aorta, your baby has a single vessel called a truncus.

Truncus arteriosus, also known as TA, is a congenital (present at birth) heart defect. It occurs when there is one main blood vessel leaving the heart instead of two, which means that the oxygenated and deoxygenated blood is combined.

2024年11月21日 · Tests to diagnose truncus arteriosus include: Pulse oximetry. A sensor placed on the fingertip records the amount of oxygen in the blood. Too little oxygen may be a sign of a heart or lung problem. Chest X-ray. This test shows the condition of the heart and lungs. It can show the size of the heart.

2024年3月10日 · Truncus arteriosus is a rare, congenital, cyanotic cardiac anomaly characterized by a ventricular septal defect (VSD), a single truncal valve, and a common ventricular outflow tract. Systemic and pulmonary venous blood mix at the VSD and desaturated blood is ejected into the outflow tract.

Truncus arteriosus happens when the blood vessel from the heart in the developing baby fails to separate completely during development. This leaves a connection between the aorta and pulmonary artery. There are several different types of truncus, depending on how the arteries remain connected.

This congenital heart disease is known as truncus arteriosus or persistent truncus arteriosus (the trunk "persists"). The undivided trunk is attached to the heart as one artery straddling the bottom chambers and then divides into arteries taking blood to the lungs and body.

In truncus arteriosus, a baby is born with only one great artery leaving the heart, instead of two. Read about symptoms, diagnosis and treatments.

Truncus arteriosus is a rare birth defect that occurs when the two main arteries of the heart don’t form correctly during fetal development. Patients with this condition have one large, wide blood vessel where two separate ones should be located.
