Figure 1 The right ventricular outflow tract (RVOT) after repair of tetralogy of Fallot assessed with cardiovascular magnetic resonance. Short axis-cardiovascular magnetic resonance TrueFISP images, end-systole, and end-diastole, at the RVOT level. (A, B) Lack of systolic thickening and inward motion of the RVOT in a tetralogy patient with transannular patch repair and RVOT akinesia (open arrows). The pulmonary valve is not visible. Black arrowhead = pulmonary regurgitant jet. (C, D) Systolic thickening and inward movement of the RVOT in a patient without patch repair (white arrows). Gray arrow = intact and competent pulmonary valve. LV = left ventricle; RV = right ventricle.
