Overview

Historical Perspective

Aortopulmonary window first described by Elliotson as a defect which causes communication between proximal aorta and main pulmonary artery. [1]

Classification

There are different ways of classifying aortopulmonary window. proximal defects are the most common between proximal aorta and sinus of valsalva. Distal types are located in the upper portion of the ascending before the aortic branches. Total defects are large and involve the majority of the ascending aorta between valsalva and aortic branches.[2]

Pathophysiology

  • Aortopulmonary (APW) window is a rare condition with presence of a communication between the ascending aorta and pulmonary artery with two separate semilunar valves.[3]
  • APW can present as an isolated phenomena but more over is assosiated with other congenital heart defects such as interrupted aortic arch, transposition of the great arteries and tetralogy of fallot.[4]

Causes

  • The cause of APW has not been identified.
  • It may be associated with some genetic disease such as DiGeorge syndrome(choromosome 22q11 deletion)[5]

Differentiating Aortopulmonary Window from other Diseases

Aortopulmonary Window must be differentiated from other diseases or conditions that cause continuous heart murmur. for further information click Here.

Epidemiology and Demographics

  • Since APW is a very rare congenital heart defect, there is very little known about epidemiology of the disease.

Risk Factors

There are no established risk factors for aortopulmonary window.

Screening

There is insufficient evidence to recommend routine screening for aortopulmonary window.

Natural History, Complications, and Prognosis

  • Clinical features of APW have been described differently due to their classification.
  • Manifestation of the disease is not specific, but majority of patients have a large left to right shunt.
  • patients with small defects may be asymptomatic.
  • If left untreated, large APW may cause symptoms of pulmonary hypertension and congestive heart failure such as tachypnea, diaphoresis, failure to thrive and recurrent respiratory difficulties.
  • pericardium is often hyperdynamic and a mitral valve rumble, causes continues heart murmur.
  • Bounding pulses happen due to decreased diastolic blood pressure secondary to aortic flow reversal in diastole.
  • If the diagnosis is not made until late in infancy or during childhood. APW may lead to eisenmenger syndrome.[6]
