Fig. 2From: Global and regional right ventricular mechanics in repaired tetralogy of Fallot with chronic severe pulmonary regurgitation: a three-dimensional echocardiography studyThe right ventricular (RV) longitudinal ejection fraction (LEF), radial ejection fraction (REF) and anteroposterior ejection fraction (AEF), and their relative contribution to global right ventricular function (RVEF) (LEF/RVEF, REF/RVEF and AEF/RVEF, respectively) in the two study groups. rToF patients demonstrated impaired LEF, REF and AEF comparing with controls. However, in rToF the relative contribution of LEF to RVEF was significantly decreased, whereas the contribution of REF and AEF to RVEF was similar to controls. * p < 0.0001Back to article page
