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.

2021年8月17日 · Truncus arteriosus (TRUN-kus are-teer-e-OH-sus) is a congenital heart defect (heart condition that’s present at birth). 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.

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.

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).

2024年10月21日 · 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.

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.

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.

The truncus arteriosus is a structure that is present during embryonic development. [clarification needed] It is an arterial trunk that originates from both ventricles of the heart that later divides into the aorta and the pulmonary trunk. [1]

Truncus arteriosus, a rare congenital heart defect, occurs during fetal development when the main pulmonary artery and the aorta artery remain connected as a single common blood vessel instead of separating into two separate arteries.
