Usefulness of Dobutamine Stress Echocardiography with Tissue Doppler Imaging for the Evaluation and Follow-Up of Patients with Repaired Tetralogy of Fallot

In patients with RTOF, impaired RV contractile reserve can be documented with TDI of tricuspid annular motion during DSE and is predicted by TDI indices at rest. Its serial estimation may contribute to optimal timing of reoperation.
