Introduction The evaluation of right ventricular (RV) function in patients with tetralogy of Fallot (TF) is important as it could impact outcome. Further exhaustive assessments with exercise might offer added information. We aimed to evaluate different parameters of RV function and their changes during exercise echocardiography (ExE) in patients with TF, and to correlate them with functional capacity Methods Treadmill ExE was performed in 31 consecutive patients with corrected TF (mean age 36 ± 11, 22 male), all of them asymptomatic. Left ventricular function was studied at peak exercise, whereas RV function parameters were acquired during the immediate post-exercise period ( Results Only 1 patient had symptoms during ExE (dyspnea). Achieved METs were 13 ± 3.5 and 10 patients (32%) had BFC. LV ejection fraction (%) changed with exercise from 58 ± 10 to 63 ± 9 (p = 0.05) and E/e´ from 11 ± 4 to 10 ± 3 (p = 0.04). TAPSE did not change (19 ± 5 at rest; 21 ± 7 at exercise; p = NS), neither RV area change (41 ± 11 cm2 at rest; 39 ± 12 cm2 at exercise; p = NS), whereas TDI-S increased from 10.5 ± 2.8 to 13.8 ± 3.1 cm2/s (p In conclusion, TDI-S assessment at the tricuspid annulus is a useful parameter for assessing RV function during exercise in subjects with TF.
