Q20.1: Double outlet right ventricle

Your main artery (aorta) and pulmonary artery both originate from the right lower chamber (ventricle) of the heart. This condition is congenital, which means you were born with it.

The heart pumps blood through the body. Inside the heart are 4 chambers. There are 2 heart atria and 2 ventricles. Both heart atria and both ventricles are separated from each other by a partition. Major, important blood vessels branch out of the heart. The main artery (aorta), originating from the left lower chamber (ventricle) of the heart, supplies the whole body with oxygen-rich blood. The right ventricle pumps oxygen-poor blood through the pulmonary artery to the lungs, where the blood is then enriched with oxygen.

Your main artery (aorta) and pulmonary artery both originate from the right lower chamber (ventricle) of the heart. You also have a hole in the wall (cardiac septum) between your ventricles. This has altered the blood flow in your heart. The blood from both ventricles mixes. This blood is a mixture of oxygen-poor and oxygen-rich blood.

The symptoms depend on factors such as where the hole in the cardiac septum is located and whether the entrance to the pulmonary artery is also narrowed. The symptoms may begin shortly after birth. Shortness of breath and becoming tired quickly are common symptoms. A low level of oxygen in the body can make the skin appear bluish in color. Normal growth may also be affected.

Additional indicator

On medical documents, the ICD code is often appended by letters that indicate the diagnostic certainty or the affected side of the body.

  • G: Confirmed diagnosis
  • V: Tentative diagnosis
  • Z: Condition after
  • A: Excluded diagnosis
  • L: Left
  • R: Right
  • B: Both sides
