Diagnostic Considerations

Distinguishing characteristics for the diagnosis of pulmonary atresia with ventricular septal defect can be divided into two major groups, as summarized below.

Decreased pulmonary blood flow in a neonate with cyanosis

Associated defects may include the following:

Normal or increased pulmonary blood flow in a neonate with minimal cyanosis with or without heart failure

Associated defects may include the following:

  • Ventricular septal defect

  • Patent ductus arteriosus

  • AV canal defect

  • A double-outlet RV without significant pulmonary stenosis

  • A single ventricle without significant pulmonary stenosis

  • Persistent truncus arteriosus

  • Total anomalous pulmonary venous connection without pulmonary venous obstruction

Consult a pediatric cardiologist, a pediatric cardiothoracic surgeon, and a geneticist.
