Pectus excavatum (PE) can cause mild lung issues, but surgery doesn't improve lung function. Post-surgery, patients show slightly better exercise tolerance, suggesting minor cardiac improvements.

Area of Science:

  • Cardiology
  • Pulmonology
  • Thoracic Surgery

Background:

  • Pectus excavatum (PE) is a chest wall deformity that may affect cardiopulmonary function.
  • Adolescents with PE often experience symptoms impacting their quality of life.

Purpose of the Study:

  • To assess cardiopulmonary abnormalities in adolescents with PE.
  • To evaluate the impact of surgical repair on these abnormalities.

Main Methods:

  • Pulmonary function tests and exercise testing were conducted on 36 adolescents with PE and 10 controls.
  • Fifteen PE patients and six controls were reassessed postoperatively.

Main Results:

  • Preoperatively, PE patients exhibited significantly lower forced vital capacity (81% vs. 98% predicted).

  • Exercise capacity was similar, but PE patients reported more exercise limitations.
  • Post-surgery, lung function remained unchanged, while exercise tolerance and O2 pulse showed modest improvements.

    • Conclusions:

    • PE can be associated with mild restrictive lung disease, unaffected by surgical correction.
    • Surgical repair may offer slight improvements in cardiac function during exercise.
    • The clinical significance of these modest postoperative gains remains uncertain.
