Indexed RV EDV Plotted Against Indexed Neoaortic Stroke Volume

Indexed right ventricular (RV) end-diastolic volume (EDV) plotted against indexed neoaortic stroke volume showing an upward and leftward shift in the curve (which resembles the Frank-Starling curve) after hemi-Fontan (HF), suggesting improved efficiency. Curves are calculated using fractional polynomial regression based on the 58 paired magnetic resonance imaging (MRI) scans; solid lines = predicted fit, dashed lines = 95% confidence intervals. MRI1 is pre-HF; MRI2 is pre-total cavopulmonary connection.
