BACKGROUND In patients with tetralogy of Fallot (TOF), left ventricular (LV) dysfunction is an important factor associated with poor clinical outcome. OBJECTIVE The purpose of this study was to investigate the torsion and multidirectional strain of the LV in patients with TOF. METHODS Echocardiographic images were prospectively acquired in 29 patients who underwent TOF repair (age range, 5-25 years) and in 29 normal controls. Torsion and circumferential and longitudinal strain of the LV… CONTINUE READING
