Cette grosse artère se trouve sur le dessus des ventricules gauche et droit, et elle est généralement accompagnée d’une communication interventriculaire. Ce trouble fait en sorte qu’une trop grande quantité de sang est acheminée vers les poumons, alors le cœur doit travailler beaucoup plus fort pour fournir une quantité normale de sang au corps.

Truncus is usually accompanied by a ventricular septal defect, resulting in blood from both ventricles mixing together. Due to this mixing, oxygen levels are lower than normal in blood that is delivered to the body. Also, because of the single trunk, extra blood flows to the lungs, and less blood reaches the body.</figcaption> </figure> <h2>What are the symptoms of truncus arteriosus?</h2><p>Symptoms include congestive heart failure and heart murmur. </p><p>A diagnosis is usually made by way of an echocardiogram or cardiac catheterization. </p><h2>How is truncus arteriosus treated?</h2><p>This defect generally requires surgery early in life. This involves closing the ventricular septal defect, separating the pulmonary arteries from the large common artery, and connecting the pulmonary arteries to the right ventricle by way of an artificial connection, or conduit. </p><h2>What is the long-term outlook for children with truncus arteriosus?</h2><p>With surgery, about 90% of children survive. The outlook is good, though additional surgery to replace the conduit may be needed later in life as your child grows. </p>Truncus arteriosus
