Device deformation and left pulmonary artery obstruction after transcatheter patent ductus arteriosus closure in preterm infants

摘要

Background: Transcatheter closure of patent ductus arteriosus (PDA) is an effective alternative to surgical ligation in preterm infants. However, data on device deformation and risk of left pulmonary artery (LPA) obstruction remain scant. This study describes the outcomes and complications of transcatheter closure of PDA in preterm infants weighing <2500 g.
