Their results were compared to RV indexed end‐diastolic volume (EDV), indexed end‐systolic volume (ESV), and RV ejection fraction (EF) at MRI.</p> </sec> <sec id="echo12386-sec-0003" sec-type="section"> <title>Results</title> <p>Twenty‐two pts (16 M) aged 11–62 years (mean 23.2 ± 10.8) were included. Parameters of RV systolic function were as follows: RVFAC = 40 ± 10%, TAPSE = 18 ± 4 mm, S‐wave = 10 ± 0.2 cm/sec, and RV EF at MRI = 43 ± 11%. Global RV systolic strain was −15.5 ± 4.2%, free wall strain was −15.1 ± 6.3%, and septal strain was −15.8 ± 3.8% on average for the whole group. Echo indexed RV end‐diastolic area correlated with EDV at MRI (r = 0.73), as well as echo indexed RV end‐systolic area and ESV at MRI (r = 0.71). Global RV 2D strain correlated well with RV EF at MRI: r = 0.68; P < 0.05, and with ESV at MRI: r = 0.63. Feasibility, intra‐ and inter‐observer reproducibility of 2D strain were adequate.</p> </sec> <sec id="echo12386-sec-0004" sec-type="section"> <title>Conclusions</title> <p>Speckle tracking is a promising method to estimate RV systolic function in pts operated on for TOF.</p> </sec> </abstract>
