Summary
Early reparative surgery for congenital heart disease in newborns has improved outcomes. However, single-ventricle defects, like hypoplastic left heart syndrome, still present challenges in neonatal intensive care units.
Area of Science:
- Pediatric Cardiology
- Neonatal Surgery
- Critical Care Medicine
Background:
- Early reparative surgery for congenital heart disease (CHD) in neonates and infants is now standard practice.
- Advancements in cardiopulmonary bypass, surgical techniques, and perioperative management have reduced mortality and morbidity.
- While successful for two-ventricle repairs, early repair strategies face challenges in newborns with single-ventricle defects, particularly hypoplastic left heart syndrome (HLHS).
Purpose of the Study:
- To review recent literature (past 12 months) on the management of newborns with single-ventricle defects.
- To identify predictors of early and late outcomes and guide patient management strategies.
- To summarize emerging research on attenuating the inflammatory response to bypass and managing postoperative complications.
Main Methods:
- Literature review of articles published within the last 12 months.
- Synthesis of findings related to classification, prenatal diagnosis, treatment options, and outcome predictors for single-ventricle defects.
- Summary of research on inflammatory response, necrotizing enterocolitis, lactate as a perfusion index, markers of injury, and mechanical circulatory support.
Main Results:
- Significant progress has been made in early reparative surgery for CHD, extending to premature and low-birth-weight infants.
- Newborns with single-ventricle defects, especially HLHS, experience higher mortality compared to two-ventricle repairs.
- Research is focusing on identifying outcome predictors and strategies to mitigate adverse responses, including inflammation, necrotizing enterocolitis, and organ injury.
Conclusions:
- While early repair has transformed CHD care, single-ventricle defects remain a critical challenge in neonatal cardiac surgery.
- Continued research into predictive markers and management strategies is essential for improving outcomes in high-risk neonates.
- Addressing the heightened inflammatory response and specific complications like necrotizing enterocolitis is crucial for advancing neonatal cardiac critical care.
