Tomographic, echocardiographic, and hemodynamic data in patients with diffuse cystic lung diseases (n = 34).

Computed tomography
Ao diameter (mm)	31 ± 4
PA diameter (mm)	29 ± 6
PA-Ao ratio	0.95 ± 0.24
Transthoracic echocardiogram
sPAP (mm Hg)∗	43 (33–46)
TRV (m/s)†	3.08 ± 0.68
Right heart catheterization
mPAP (mm Hg)	28.6 ± 10.1
PVR (wood units)	3.2 (2.4–4.1)
CO (L/min)	4.7 ± 1.0
Wedge pressure (mm Hg)	11.6 ± 4.9

Data are presented as mean ± SD or median (25th–75th percentile). Ao = ascending aorta, CO = cardiac output, mPAP = mean pulmonary artery pressure, PA = pulmonary artery, PVR = pulmonary vascular resistance, sPAP = systolic pulmonary artery pressure, TRV = tricuspid regurgitation velocity.
