Figure 2. Significant relationships were found between APC flow and enddiastolic (r=0.40, p=0.002), endsystolic (r=0.29, p=0.026) and stroke volume (r=0.36, p=0.005) of the single ventricle (n = 60 patients).

There was no relationship between the degree of APC flow and ventricular function expressed as ejection fraction (r=-0.07, p=0.57).
