Managing Congenital Lobar Overinflation Associated with Congenital Heart Disease

The incidence of congenital lobar overinflation (CLO) is reported at 1 in 20,000-30,000 live births and represents 10% of all congenital lung malformations. The occurrence of concomitant congenital heart disease (CHD) and CLO ranges from 12% to 20%. There are diverging views in the management as to whether early lobectomy or repair of the cardiac defect, with the assumption that respiratory symptomatology would gradually resolve, or a combined lung and cardiac repair would be the ideal first step in the management. In concomitant CLO and CHD, the surgical decision has to be individualized. Prior to surgical intervention a thorough evaluation may be needed with contrast computed tomography (CT) or magnetic resonance imaging (MRI), bronchoscopy, and if needed cardiac catheterization. CLO improves with management of many left to right shunts and in those with anomalous vessels, but early lobectomy or combined approach may be considered in those symptomatic patients with more complex CHD
