Pulmonary artery banding using expanded polytetrafluoroethylene suture

Pulmonary artery banding (PAB) is essential for infants of complicated cardiac anomaly without pulmonary stenosis, especially those who require future Fontan type correction. In order to avoid pulmonary artery branch stenosis or uneven growth we utilize expanded polytetrafluoroethylene (E-PTFE) suture (Gore-Tex suture, CV-0) as a banding material. We performed three PABs (two newborns and one infant) with this suture. All children were doing well after the banding and no one revealed residual pulmonary hypertension or pulmonary artery distortion in the postoperative catheter study. One patient successfully underwent total cavopulmonary connection eight months after PAB. We believe E-PTFE suture is an advantageous material of PAB for newborns and young infants.
