Postoperative complete repair of tetralogy of Fallot

Measure right ventricular size and assess function
Assess septal motion and right ventricular hypertrophy
Image and colour of right ventricular outflow tract, pulmonary artery and branches
Measure maximum velocity at any areas of aliasing
Assess pulmonary and tricuspid regurgitation from colour signals
Measure right ventricular pressure from tricuspid regurgitation velocity
Look for a residual ventricular septal defect
Measure aortic root size and look for aortic regurgitation
Remember in distal obstruction imaging poor and spectral velocity unreliable
•  right ventricular pressure may give better indication of obstruction
