Diagnostic Considerations

Important considerations

It is important to recognize symptoms and signs of coexistent aortic arch obstruction.

Clinicians should also be able to recognize inadequately relieved subaortic stenosis, aortic stenosis, or both.

Children with single ventricle cardiac physiology often require airway evaluation and intervention, and those with high-risk cardiac procedures are at greater risk for recurrent laryngeal nerve injury. [53] The best predictor for need of a tracheostomy in these patients appears to be the presence of subglottic stenosis. [53]

Other problems to be considered

Also consider the following conditions when evaluating patients with suspected single ventricle:

  • Pulmonary stenosis or complex heart malformation with pulmonary stenosis as a component

  • Arch obstruction or complex heart malformation with aortic stenosis, arch obstruction, or both as a component

  • Neonatal sepsis
