Abstract

Transcatheter closure of a patent ductus arteriosus (PDA) has always been considered risky for infants weighing <6 kg and preterms. We present our findings regarding transcatheter closures of PDA. The inclusion criteria were a weight of <6 kg and the presence of PDA symptoms. The study subjects were divided into two groups: <6 kg and premature infants. A total of 69 infants were included.
