Mustard & Senning Procedure
|
|
|
The Mustard’s operation is
undertaken for transposition of the great arteries and is sometimes known as the “trouser” graft. A pair of
trousers are fashioned from pericardial tissue. The atrial septum is
removed. One leg collects the SVC flow and the other the IVC flow. The
waistband is stitched over the mitral valve thus directing the
desaturated systemic venous return into the LV and thence to PA
The fully
oxygen saturated pulmonary venous return cannot
drain across the mitral valve and thus passes around the trousers to
the RA, through the tricuspid valve to the RV and thence to aorta.

| The original concept of this operation was Senning's (1958) who instead of using pericardial baffle created the baffles by reshaping the atrial walls. Mustard's modification was undertaken to allow it to be performed in younger babies but unfortunately the pericardium often shrank and the pathways became stenosed. For the most part both operations were superceded by the arterial switch procedure. |

| The baffles used to steer the blood in the right direction may become stenosed. They usually respond to balloon dilation as seen here but stent implantation may be required. |
