Fig. 3From: Left and right ventricular dyssynchrony and strains from cardiovascular magnetic resonance feature tracking do not predict deterioration of ventricular function in patients with repaired tetralogy of FallotChanges in LV (a) and RV (b) ejection fraction (EF) over time, with patients divided into 4 groups based on the four quartiles of baseline LV peak circumferential strain of the patients. ∆LVEF and ∆RVEF were calculated with respect to the baseline value for each subject. A straight line was fitted to each group using linear regression to facilitate visualizing group differences in changes in EF over timeBack to article page
