Living with Congenital pulmonary venous return anomaly

A heart development difference in which some or all of the lung veins drain to the wrong place.

Understanding Congenital pulmonary venous return anomaly

Congenital pulmonary venous return anomaly is a rare heart development difference in which some or all of the lung veins drain into the wrong part of the circulation.

The veins drain into the right upper heart chamber or into body veins instead of the correct place. There may or may not be a blockage in the veins. It has two main types: partial (only one or a few veins are affected) and total (all of the lung veins are affected).

Signs & symptoms

Symptoms vary from person to person. GARD's summary mentions these:

  • Tiring easily (fatigue)
  • Shortness of breath with activity
  • High blood pressure in the lung arteries
  • Bluish skin color (cyanosis)
  • Heart failure that gets worse over time

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include heart and blood vessel specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
