Living with Aortic arch defects

Differences in how the curved part of the main heart vessel formed before birth, sometimes pressing on the airway or food pipe.

Understanding Aortic arch defects

Aortic arch defects are differences present from birth in how the curved part of the aorta (the main blood vessel from the heart) developed.

They happen when parts of the early blood vessel system in the embryo shrink or stay when they shouldn't. This leads to many possible differences. Some cause physical problems and some do not. Problems can include pressure on the windpipe or food pipe and unusual blood flow. GARD lists onset in childhood.

Signs & symptoms

GARD doesn't list specific symptoms for this condition, but its summary describes these possible problems:

  • Pressure on the windpipe and airways (tracheobronchial compression)
  • Pressure on the food pipe (esophageal compression)
  • Unusual blood flow patterns

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 and lung and breathing specialists.

  3. Ask which tests can help

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