Implication

Observational study reveals impaired lung diffusing capacity and air trapping in children with Fontan circulation, indicating pulmonary abnormalities reduce physical capacity.

Key Points

To investigate the pattern of pulmonary function impairment and evaluate its association with decreased exercise capacity in children who underwent total cavopulmonary connection.
Assessed 33 eligible children in Norway (aged 8 to 16 years) with a total cavopulmonary connection (Fontan circulation).
Conducted spirometry, whole-body plethysmography, carbon monoxide single-breath testing, and peak treadmill exercise testing.
Corrected diffusing capacity averaged 66.5% of predicted (z-score -2.88) and peak treadmill exercise capacity averaged 70.0% of predicted (z-score -3.07).
Residual volume was 146.8% of predicted (z-score 2.46) by plethysmography compared to 102.4% (z-score 0.43) by single-breath testing, demonstrating air trapping, while mean forced vital capacity was 85.7% (z-score -0.92).
