What is truncus repair?

Also known as: truncus arteriosus repair, repair of truncus arteriosus.

Truncus arteriosus is a heart defect present at birth. Babies with the defect only have one large artery carrying blood to the body and lungs, rather than the two vessels (the aorta and pulmonary artery) that they should have. This great vessel usually has one large valve which may have between two and five leaflets.

Truncus arteriosus is also present with a ventricular septal defect (VSD), or a hole between the heart’s ventricles. Truncus repair is a surgery to solve these problems.
