What are the symptoms of single ventricle defects?

In most cases, the symptoms of single ventricular defects are usually noted shortly after birth. The most common include:

  • blue color of the skin, lips and nailbeds (cyanosis)
  • rapid breathing
  • labored breathing
  • rapid heart rate
  • cool, clammy skin

What causes single ventricle defects?

Single ventricle defects occur within the first eight weeks of a baby’s development, when the heart is first formed. Most of the time, these types of heart defects occur with no clear reason. Some congenital heart defects may have a genetic link, causing heart problems to occur more often in certain families.
