Summary

This study tests if the drug milrinone can prevent a serious heart complication called post-ligation cardiac syndrome (PLCS) in very preterm infants after surgery to close a heart vessel. About 316 babies born before 28 weeks will receive either milrinone or standard care. The goal is to see if milrinone reduces death or PLCS within a week and improves survival and brain development at age two.
