Comparisons of Pre-Fontan Hemodynamic Data by Cardiac Catheterization Between Survivors and Nonsurvivors

Nonsurvivors (n = 15)Survivors (n = 63)p Value
Pulmonary artery pressure (mm Hg)17 ± 713 ± 40.03
Transpulmonary gradient (mm Hg)7 ± 26 ± 30.17
LVEDP (mm Hg)8 ± 38 ± 30.84
BVF gradient (mm Hg)14 ± 229 ± 140.28
Pulse oximetry (%)85 ± 683 ± 70.37
Qp/Qs ratio1.8 ± 1.01.3 ± 0.70.15

Data are presented as the mean value ± SD.

BVF = bulboventricular foramen; LVEDP = left ventricular end-diastolic pressure; Qp/Qs = pulmonary blood flow to systemic blood flow ratio.
