Can transcatheter PDA closure be performed in neonates ≤1000 grams? The Memphis experience.

Advancements in transcatheter technology have now made it possible to safely close patent ductus arteriosus (PDA) in extremely low birth weight (ELBW) infants. The objective of this article is to describe our technique for transcatheter PDA closure (TCPC) in ELBW infants. The techniques employed are very specific to this population and are drastically different when compared to the procedure performed in patients weighing >5 kg. A multidisciplinary team approach should be taken to evaluate and manage ELBW infants in order to achieve success. It is important that specific techniques with venous-only approach outlined in this article be followed to achieve optimal results with low risk of complications. To date, in Memphis, 55 ELBW infants have had successful TCPC at a weight of ≤1000 g with minimal procedure-related complications. It is important that specific techniques with venous-only approach outlined in this article be followed to achieve optimal results with low risk of complications. This procedure entails a steep learning curve and should be limited to specialized centers with expertise in these thanscatheter procedures. There has been 100% procedural success of performing TCPC in children ≤1000 g. There have been only two procedure-related complications which happened to the first two patients, ≤1000 g, that we performed TCPC on. It is feasible and probably safe to perform TCPC in children ≤1000 g. The techniques described in this article represent our institutional experience and have helped us improve clinical outcomes in ELBW infants.
