Short answer · Medically reviewed summary · Last updated: 2026-05-08
Truncus arteriosus is a rare congenital heart defect where a single large blood vessel leaves the heart instead of the two separate vessels (the aorta and pulmonary artery) seen in a healthy heart. It is most commonly referred to by this name in modern clinical settings, though it is historically known as persistent truncus arteriosus or common arterial trunk. What are the alternative names for Truncus Arteriosus? While truncus arteriosus is the standard medical term, you may encounter several synonyms in older medical records, textbooks, or international literature.

While truncus arteriosus is the standard medical term, you may encounter several synonyms in older medical records, textbooks, or international literature. These variations often reflect historical efforts to describe the anatomy before modern imaging. Common synonyms include:
The naming of truncus arteriosus has evolved alongside our understanding of cardiac embryology. Historically, the term "persistent" was often added to emphasize that the fetal structure failed to divide into the aorta and pulmonary artery. Modern classification systems, such as the International Classification of Diseases (ICD-10 code Q20.0), now prefer the simpler, more direct term truncus arteriosus. These names describe the same underlying condition, but the shift toward simplified terminology helps standardize communication between international cardiologists and surgeons.
For patients and researchers seeking data, it is helpful to know how truncus arteriosus is categorized in authoritative registries. Using these codes can help when searching for specific clinical literature:
