• Fetal diagnosis

  Usually, doctors can diagnose double-outlet right ventricle when a baby is in the womb using a fetal echocardiogram (fetal echo). This is a special ultrasound that uses sound waves to view and make pictures of a developing baby’s heart during pregnancy. The results are interpreted by a pediatric heart doctor (cardiologist) who specializes in fetal congenital heart disease.

  Your obstetrician may refer you for a fetal echo if your family has a history of congenital heart disease or if a routine prenatal ultrasound shows a problem.

  Our Fetal Care and Treatment Center team can care for you when you are pregnant if your developing baby has a known or suspected problem.

• Diagnosis after birth

  To diagnose this condition, your child’s doctor will examine your child, check their heartbeat and pulse and listen to their heart. In children with double-outlet right ventricle, doctors might be able to hear a heart murmur – the sound of blood moving in the heart in a way that’s not normal.

  The doctor will ask for details about your child’s symptoms, their health history and your family health history.

  Your child will need tests that provide more information about how their heart looks and works. These will most likely include:

  • Echocardiography
  • Chest X-rays
  • Electrocardiography (ECG or EKG)

  Your child may also need these tests: 

  • MRI (magnetic resonance imaging)
  • CT (computed tomography) scan
  • Cardiac catheterization

Children with double-outlet right ventricle need surgery to correct the condition. The exact procedures and timing depend on your child’s condition, how severe it is and whether they have other heart defects too. Usually, surgery is done within the first several days to months after birth. Often children need more than 1 surgery or procedure.

• Surgery

  In general, children need surgery to do the following: 

  • Direct oxygen-rich blood, which comes from the lungs, into the aorta. From there, it can be carried to the rest of their body.
  • Keep oxygen-poor blood, which comes back from the body, out of the aorta. This blood needs to go to your child’s lungs first to pick up oxygen.
  • Close any other abnormal holes in the heart. This step keeps oxygen-rich blood from mixing with oxygen-poor blood. 

  How doctors achieve these goals depends on the kind of double-outlet right ventricle your child has. The cardiologist and surgeon taking care of your child will talk with you about the best approach for your child’s heart.

  Most children have surgery that allows both ventricles to pump blood where it needs to go. For children with some complex defects, the best approach is surgery that allows one ventricle to do all the pumping. The team in our Single Ventricle Program provides specialized care for these children.

  All children with double-outlet right ventricle will need lifelong follow-up with a cardiologist who specializes in congenital heart defects.

• Medicine

  To get ready for surgery, your child may need medicines like these: 

  • Diuretics, which help the kidneys rid the body of extra water
  • Angiotensin-converting enzyme (ACE) inhibitors, which lower blood pressure
  • Digoxin, which makes the heart beat slower and with more force
• Transplant

  In rare cases, the heart cannot be repaired, and doctors may recommend a heart transplant. The heart transplant team at Seattle Children’s is one of the best in the nation, caring for children with this or other heart problems that cannot be controlled using other treatments.
