Maldistribution of pulmonary blood flow in patients after the Fontan operation is associated with worse exercise capacity

Table 3 Multivariable Model for % Predicted VO₂ (n = 140)

Variable	Standardized β coefficient	Parameter Estimate ± SE	P value
Maldistribution of pulmonary blood flow	−0.20	−5.4 ± 2.6^a	0.03
Time since Fontan (year)	−0.32	−0.67 ± 0.18^b	0.002
Ventricular mass-to-volume ratio (g/ml)	−0.24	−19.38 ± 6.60^b	0.02

^aMean difference ± SE for presence vs. absence of maldistribution of pulmonary blood flow
^bSlope ± SE.SE = standard error
