title: Bilateral banding of malpositioned pulmonary artery branches.
abstract: This report presents two rare cases of malpositioned pulmonary artery branches managed by bilateral banding. The left-branch pulmonary artery, originating from and directly superior to the right branch, entered the posterior mediastinum before heading toward the left pulmonary hilum. The ostium of the left branch could not be visualized by midline sternotomy. Therefore, a double-subtraction technique was used to pass the banding tape around the left branch from the right side. The tape location was adjusted and confirmed by intraoperative echocardiography.
