What should be evaluated by echocardiography in patients after Tetralogy Fallotsurgery

<p>Evaluated by echocardiography in patients after TetralygFallot surgery  with 2D Echo / Colour Doppler repaired include:  assessment of the right ventricular size, systolic function (visual, TAPSE, MPI),  left ventricular  function,  paradoxical IV septal motion, suggesting right ventricular  volume overload, residual VSD, size, turbulence , aortic root size, aortic regurgitation, residual right ventricular outflow tract  obstruction, turbulence on color flow, degree of pulmonary regurgitation, degree of right ventricular hypertrophy, best seen from sub-costal views Doppler Measurements include: residual VSD V max,  restrictive/ unrestrictive jet right ventricular outflow tract  obstruction, sites, degree (using peak PG derived from Bernoulli : 4V2) : including branch pulmonary arteries, degree of pulmonary regurgitation,  CW jet intensity, , early diastolic jet termination, right ventricular  diastolic dysfunction (restrictive physiology) – antegrade late diastolic flow in mean pulmonary artery  on PW Doppler, coinciding with atrial systole. Utilize stand-alone CW Doppler to search for high velocity signals suggestive of peripheral pulmonary stenosis. Limitations: deriving on colour Doppler at severe pulmonary regurgitation  may be underestimated</p>
