Atypical Presentation of a Large Aortopulmonary Window in a Very Low Weight and Preterm Born Infant

of a Large Aortopulmonary Window in a Very Low Weight and Preterm Born Infant. 370-373. Abstract Background Aortopulmonary window represents 0.2-0.3% of all congenital cardiac malformations. Usually, aortopulmonary window results in left-to-right shunt. Thus, progressive pulmonary hypertension and its consequences are associated with this anomaly. Commonly, it is located in the ascending aorta. Case Presentation We are describing a premature low-birth-weight infant who was diagnosed with large aortopulmonary window between the pulmonary artery bifurcation and the ascending aorta extending to the aortic arch. Surgery was successfully performed at the age of 4 weeks due to progressive congestive heart failure. This report highlights the importance of early surgical repair in patients with complex aortopulmonary window configuration.
