Early diagnosis of Truncus Arteriosus saves your life

Learn about Truncus Arteriosus, its causes, symptoms, treatment options, and expert advice to manage this rare congenital heart defect effectively.

12 September, 2025

Truncus Arteriosus is a rare congenital heart defect that affects newborns. Early detection and proper treatment can improve outcomes and save lives.

What are the main causes of truncus arteriosus?

  • A genetic mutation affecting heart development during pregnancy can lead to truncus arteriosus, altering the structure of the major blood vessels.
  • Maternal health conditions, such as poorly controlled diabetes or viral infections, may significantly increase the risk of this congenital heart defect.
  • Environmental exposures, including certain medications or alcohol during pregnancy, can disrupt normal fetal cardiac development and contribute to truncus arteriosus.

Key symptoms of truncus arteriosus to watch for

  • Infants may present with bluish skin color (cyanosis) due to poor oxygen circulation, signaling an urgent congenital heart defect needing immediate evaluation.
  • Rapid breathing, shortness of breath, or frequent respiratory infections are common signs indicating truncus arteriosus and require prompt medical attention.
  • Poor feeding and inadequate weight gain in newborns are frequent early warning signs that may point toward an underlying heart defect.

How can you prevent truncus arteriosus effectively?

  • Maintaining optimal maternal health before and during pregnancy, including controlling diabetes and avoiding harmful exposures, lowers the risk of congenital defects.
  • Prenatal care with regular ultrasounds and genetic counseling helps detect potential abnormalities early, allowing for informed decisions and timely medical interventions.
  • Avoiding alcohol, smoking, and unsafe medications during pregnancy significantly decreases the likelihood of truncus arteriosus and other congenital heart issues.

Truncus arteriosus is a rare congenital heart defect where a single blood vessel arises from the heart instead of two separate arteries, causing mixed oxygen-rich and oxygen-poor blood.
