Symptoms of Double Inlet Left Ventricle

Double inlet left ventricle allows oxygen-rich (red) and oxygen-poor (blue) blood to mix in the heart and get pumped out to your child’s body. So this heart defect causes symptoms linked to poor oxygen supply.

Blood may back up in your child’s veins, too. This happens because there’s only one ventricle, instead of two, to do the work of pumping blood.

Your child may have symptoms like these:

  • Getting tired easily
  • Bluish skin, lips or nailbeds (cyanosis) or pale skin
  • Trouble feeding
  • Trouble gaining weight and growing
  • Fast breathing or trouble breathing
  • Sweating more than normal
  • Edema, or swelling, in the legs and abdomen

Double Inlet Left Ventricle Diagnosis

To diagnose this condition, your doctor will examine your child, check their heartbeat and listen to their heart. In children with double inlet left ventricle, doctors can often 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 also need tests that provide more information about how their heart looks and works. These may include chest X-rays or MRI (magnetic resonance imaging) of the heart, cardiac catheterization, echocardiography and electrocardiogram.
