Case in brief
A man who had undergone right upper lobectomy for congenital pulmonary airway malformation (CPAM) at 6 months of age presented in adulthood with restrictive ventilatory impairment, including markedly reduced FVC and FEV₁ with elevated FEV₁/FVC. Minor arrhythmia, pectus excavatum, and mild mitral valve prolapse were also noted. Once-weekly aerobic training was added to his ongoing resistance program under supervision and was feasible and generally well tolerated. Afterwards, submaximal walking heart rate, estimated strength, and selected St. George’s Respiratory Questionnaire scores improved; the activity domain was essentially unchanged. The single-case observations do not establish causality.
What made this case unusual
The report describes exercise-training responses in an adult with persistent ventilatory limitation after early-life lobectomy for CPAM, a population for which the authors note that evidence is scarce.
Diagnostic / clinical pearl
After lobectomy for CPAM, persistent low FVC and FEV₁ with an elevated FEV₁/FVC may indicate restrictive ventilatory impairment; supervised exercise responses can be assessed without assuming that observed changes are caused by the added training.
