Role of Stress Echocardiography in Operated Fallot: Feasibility and Detection of Right Ventricular Response

Ex-Echo is feasible in patients with repaired tetralogy of Fallot and allows the integrated assessment of variation in RV systolic pressure, area, and function during exercise, which usefully complement more conventional indices of hemodynamic burden in these patients. Longitudinal follow-up is needed to better delineate the prognostic value of the results of Ex-Echo.
