Fig. 2From: Right-left ventricular shape variations in tetralogy of Fallot: associations with pulmonary regurgitationModel-based LV and RV dimension calculations. Green: LV; Purple: RV; Maroon: Epicardium. A Biventricular model and intersecting planes. B Long axis plane showing how apical angle (β), tricuspid tilt (α), and basal bulge (d) were calculated. C Mid-ventricular short axis view showing LV and RV lateral to septal dimensions (D1 and D3 respectively) and RV and LV anterior–posterior dimensions (D2 and D4 respectively)Back to article page
