-
- Idiopathic Dilatation of the Pulmonary Artery (IDPA) is a rare congenital
- defect characterized by a wider than normal main pulmonary artery in the
- absence of any apparent anatomical or physiological cause.
-
- Symptoms
-
- Idiopathic Dilatation of the Pulmonary Artery commonly doesn't produce
- symptoms because there is no circulation abnormality. Clinical signs are
- minimal and consist of a palpable pulmonary ejection sound which disappears
- when one inhales, a soft pulmonary ejection systolic murmur (abnormal heart
- sound) and splitting of the second sound on breathing in. Idiopathic
- Dilatation of the Pulmonary Artery does not cause pulmonary valve disease,
- nor does bacterial endocarditis occur in patients with this condition. The
- electrocardiogram is normal, and diagnosis is made when chest X-rays reveal a
- dilated pulmonary artery without cardiac chamber enlargement.
-
- Causes
-
- The cause of Idiopathic Dilatation of the Pulmonary Artery is unknown. A
- defect in the normal development of pulmonary artery elastic tissue before or
- after birth has been postulated. The dilatation may also be a consequence of
- a generalized connective tissue disease as it is occasionally found in
- Marfan's syndrome or Ehlers-Danlos syndrome. (For more information on these
- disorders, choose "Marfan" and Ehlers-Danlos" as your search terms in the
- Rare Disease Database.
-
- Therapies: Standard
-
- Treatment for Idiopathic Dilatation of the Pulmonary Artery is not required.
- People with this condition have a normal life expectancy, provided they have
- no cardiac lesions.
-
- Therapies: Investigational
