Recurrent PDA refers to the reopening of the ductus arteriosus after it has initially closed. This may occur due to several factors, such as:
- Prematurity: Incomplete development of the heart and blood vessels. - Genetic Factors: Certain genetic conditions may predispose infants to PDA. - Infections: Neonatal infections can exacerbate or trigger the reopening of the ductus arteriosus. - Respiratory Distress Syndrome (RDS): This common condition in preterm infants can lead to increased pulmonary blood flow and pressure, contributing to PDA.
