What is Truncus Arteriosus

Truncus arteriosus is a rare congenital heart defect that occurs during fetal development. It is characterized by a single large blood vessel, known as the truncus arteriosus, arising from the heart instead of the normal two separate vessels (aorta and pulmonary artery). This condition occurs when the embryonic heart fails to develop normally.

Truncus arteriosus leads to mixing of oxygenated and deoxygenated blood, resulting in inadequate oxygen supply to the body. Infants with this condition often experience symptoms such as difficulty breathing, poor feeding, and bluish skin coloration.

Early diagnosis and prompt treatment are crucial for managing truncus arteriosus. Surgical intervention is typically required to repair the defect and separate the aorta and pulmonary artery. This procedure involves creating a new pulmonary artery and closing the ventricular septal defect, if present.

Long-term outcomes for individuals with truncus arteriosus depend on various factors, including the severity of the defect, associated complications, and the success of surgical intervention. Regular follow-up care and monitoring are essential to ensure optimal heart function and overall well-being.
