The common arterial trunk (TAC), also called (persistent) arterial trunk , is a very rare congenital heart malformation with 1% , in which the aorta ( large body artery ) and pulmonary trunk (pulmonary artery) were not completely separated during fetal development, i.e. H. their spiral-shaped septum separating them is defective. Therefore, both arteries arise together from the heart as a persistent Truncus arteriosus communis. Often there is also a ventricular septal defect . The aortic valveis called the "trunk valve" for this heart defect. In many cases it is malformed and as a result it can be too wide or too narrow. There are different forms of this heart defect.
As part of the circulatory change after the birth , the resistance of the pulmonary vessels decreases. This increases the blood flow to the lungs ( with the resulting risk of developing pulmonary hypertension ), which can initially lead to breathing difficulties in the child and ultimately to heart failure due to the malfunctioning trunk valve . Therefore, an operation with the help of the heart-lung machine is usually necessary in infancy .
Echocardiography and cardiac catheterization are used for diagnosis .
Lifelong check-ups are necessary and strict attention must also be paid to endocarditis prophylaxis .
