(F)utility of preoperative pulmonary function testing in pectus excavatum to assess severity

Topic overview

Key takeaways

• 48% of pectus excavatum patients failed to complete preoperative PFT, questioning its routine utility in surgical assessment.
• PFT completion status did not correlate with pectus severity indices, cardiac deformation, or patient symptoms.
• Inability to complete PFT should not be interpreted as a marker of more severe pectus excavatum deformity.
• Cardiac MRI and cardiopulmonary exercise testing may be more reliable than PFT for preoperative PE assessment.
• Routine preoperative PFT in pectus excavatum has limited clinical utility given high non-completion rates and lack of severity correlation.
