Mustard operation
An atrial switch procedure using a pericardial baffle to redirect venous return in patients with transposition of the great arteries.
Full Definition
The Mustard operation is an atrial switch procedure developed to treat transposition of the great arteries by creating an intra-atrial baffle using pericardial or synthetic material. The baffle redirects systemic venous return to the left ventricle (which connects to the pulmonary artery) and pulmonary venous return to the right ventricle (which connects to the aorta). While historically important, the Mustard operation has been largely superseded by the arterial switch operation due to long-term complications including baffle obstruction, arrhythmias, and right ventricular dysfunction. Patients who underwent Mustard repair require lifelong cardiac follow-up.
Usage
Usage note: Historical procedure; patients require specialized adult congenital cardiac care.
