Pulmonary function is significantly impaired in most patients after complete transposition repair, showing increased lung stiffness and reduced lung volumes. These changes may negatively impact long-term outcomes for these individuals.

Area of Science:

  • Cardiology
  • Pulmonary Medicine
  • Pediatric Surgery

Background:

  • Simple complete transposition of the great arteries is a congenital heart defect requiring surgical correction.
  • Intracardiac repair aims to restore normal blood flow but can affect pulmonary function.
  • Long-term pulmonary sequelae after surgical repair are not fully understood.

Purpose of the Study:

  • To assess pulmonary function in patients with simple complete transposition after intracardiac repair.
  • To identify specific patterns of lung dysfunction and their prevalence.
  • To explore correlations between lung function, patient age, and hemodynamic parameters.

Main Methods:

  • Pulmonary function tests were conducted in 35 patients (mean age 11.6 years) post-intracardiac repair.

  • Measurements included static recoil pressure, lung compliance, vital capacity, and total lung capacity.
  • Analysis involved comparing patient data to normal values and assessing correlations.

    • Main Results:

    • 88% of patients exhibited abnormal pulmonary function.
    • Increased static recoil pressure (66%) and decreased static lung compliance (75.1% of predicted) were common.
    • Reduced vital and total lung capacity, with increased residual volume and hyperinflation, were observed.

    Conclusions:

    • Significant pulmonary dysfunction, including lung stiffness and restricted volumes, is prevalent post-transposition repair.
    • These functional changes may adversely affect long-term outcomes.
    • Further research is needed to understand the clinical implications of these findings.
