Interventional closure of patent ductus arteriosus in infants smaller than 5000 g - single center experience of thirteen consecutive cases over 2 years

Introduction: Occlusion of patent ductus arteriosus (PDA) in small infants is in many centers still a domain of cardiac surgery that can be performed with little technical effort but still bares the risks of any open surgical therapy. Interventional therapy has recently evolved in the field of PDA occlusion. New device technology with miniaturized devices and softer, more flexible equipment require smaller introducer sheathes, may prevent distortion of the anatomy during implantation and therefore is more suitable in smaller infants.
