Article Abstract

Postoperative pulmonary artery stenosis: current options and future directions

Authors: David Kalfa


This study by Kim et al. (1) addresses an important and frequent issue in pediatric cardiac surgery, which is the management of postoperative pulmonary artery (PA) branches stenoses. Different options are currently available to treat a PA branch stenosis, including a conventional surgical plasty using (or not) a biological patch (autologous pericardium, human cryopreserved pericardium, bovine or equine pericardium, or decellularized porcine intestinal submucosa extracellular matrix) or a synthetic patch (polytetrafluoroethylene, terephtalate, ...), percutaneous procedures (balloon dilation, stent placement, cutting balloon dilation, ...) and hybrid procedures.
