Assessment of ductal blood flow in newborns with obstructive left heart lesions by cardiovascular magnetic resonance

Table 3 CMR findings of patients according to the type of treatment: univentricular or biventricular

Variables	Univentricular	Biventricular	P
PDA flow* (L/min/m²)	1.70 (0.56 to 2.53)	0.61 (−1.48 to 3.23)	0.0147
AAo flow (L/min/m²)	0.56 (−0.19 to 1.08)	1.82 (−0.16 to 2.92)	0.0006
Contribution of PDA to Qs (%)	56.59 (39.77 to 100)	24.14 (−87.16 to 100)	0.0013
LVEDVi (ml/m²)	15.75 (11.8 to 30.3)	27 (17.7 to 71.2)	0.024
AR ratio	0.72 ± 0.14 (0.52 to 0.92)	0.54 ± 0.17 (0.28 to 0.89)	0.01

*negative values denote a left-to-right shunt.
^†negative percentages denote a contribution of aortic arch flow to pulmonary blood flow via a left-to-right shunt across the PDA.
AAo ascending Aorta, AR ratio antegrade/retrograde duration ratio, LVEDVi LV end-diastolic volume index, PDA patent ductus arteriosus.
