Truncus Arteriosus is a rare congenital heart defect characterized by a single large blood vessel arising from the heart, instead of the normal two separate vessels (aorta and pulmonary artery). It accounts for approximately 1-3% of all congenital heart defects. The prevalence of Truncus Arteriosus is estimated to be around 1 in every 10,000 live births. It is more commonly observed in males than females. Early diagnosis and surgical intervention are crucial for the management of this condition.
Truncus arteriosus is a rare congenital heart defect characterized by a single large blood vessel arising from the heart, instead of the normal two separate vessels (aorta and pulmonary artery). This condition occurs during fetal development when the heart does not form correctly.
The prevalence of truncus arteriosus is estimated to be around 1 in every 10,000 live births. It accounts for approximately 1-3% of all congenital heart defects. Although it is considered a rare condition, it is one of the most common types of cyanotic congenital heart diseases, which are characterized by low oxygen levels in the blood.
Truncus arteriosus is more commonly observed in certain populations, such as individuals with DiGeorge syndrome or 22q11.2 deletion syndrome. Additionally, it is slightly more prevalent in males than females.
Early diagnosis and prompt medical intervention are crucial for managing truncus arteriosus. Treatment typically involves surgical repair to separate the single blood vessel into the aorta and pulmonary artery, allowing for improved blood flow and oxygenation.
