Mustard or Senning procedure

Measure right (systemic) ventricular size and assess function
Assess systemic atrioventricular (tricuspid) regurgitation
Use colour flow imaging to assess systemic or venous baffle obstruction
Use colour flow imaging to determine presence of baffle leak
If appropriate use contrast to look for obstruction or leak
Assess pulmonary pressure from velocity of mitral regurgitation
Exclude left ventricular outflow tract obstruction
Use transoesophageal imaging if precordial ones are not satisfactory
Remember the right ventricle is the systemic one and the left the pulmonary
