Patent Ductus Arteriosus in Preterm Infants

Despite extensive research in basic science and in clinical settings with thousands of infants over decades, uncertainty and controversy persist regarding the significance, assessment, and management of the patent ductus arteriosus (PDA) in preterm infants, resulting in substantial variability in clinical approach. This clinical report aims to succinctly review the available evidence to guide evaluation and treatment of preterm infants with prolonged ductal patency.
