Implication

Lung mechanics may warrant evaluation in ASD without PH; leaves open whether changes predict outcomes or respond to intervention.

Structured PICO

P
Population
24 adult patients with atrial septal defect, divided into 3 groups according to mean pulmonary artery pressure: less than 19 mm Hg, 20 to 24 mm Hg, and greater than 25 mm Hg
O
Outcome
Mechanics of breathing and pulmonary diffusing propertiessurrogate

Increased pulmonary blood volume and high intravascular pressure in patients with atrial septal defect lead to significant abnormalities in lung mechanical behavior, likely due to compression of small airways.
