Summary: This week we explore the role of transcatheter closure of the PDA in the infant, particularly those < 2 kg and even < 1 kg. We review data from the IMPACT trial on closure of the PDA in small infants and also discuss an important paper by Dr. Evan Zahn on transcatheter closure of PDA's in the premature or very small infant. What are the outcomes when closing the PDA in a small infant? What are the possible benefits or risks? Dr. Zahn offers many answers and also gives us some insights into the near future of this rapidly developing approach to the transcatheter management of the large duct in a small child.
