What is the prognosis (outlook) for children who have double inlet left ventricle?

Factors that affect how well a baby with double inlet left ventricle does include:

  • How severe the defect is.
  • The overall condition of the baby when the diagnosis is made.
  • Whether other heart defects are present.
  • Genetic syndromes.

Many babies with double inlet left ventricle live to adulthood as a result of advances in surgical procedures. Many people with double inlet left ventricle need regular follow-ups. In addition, they can face various complications and their physical activity can be limited.
