Hypoplastic left heart syndrome: Prognosis and management options

Area of Science:

• Pediatric Cardiology
• Congenital Heart Disease
• Neonatal Surgery

Background:

• Hypoplastic left heart syndrome (HLHS) is a severe congenital heart malformation.
• Historically, HLHS had a >95% mortality rate within the first month of life.
• Recent decades introduced palliative surgery and cardiac transplantation as management options.

Purpose of the Study:

• To describe current risk factors, diagnosis, treatment, and outcomes for infants with HLHS.
• To highlight the challenges in decision-making due to unknown long-term results of new therapies.
• To emphasize the need for further research on long-term outcomes of surgical interventions.

Main Methods:

• Review of current literature on HLHS management.
• Analysis of risk factors, diagnostic approaches, and treatment modalities.
• Discussion of ethical, social, and economic implications.

Main Results:

• Prenatal diagnosis allows for informed family counseling and decision-making.
• Surgical interventions offer survival hope but lack defined long-term outcomes.
• Comfort care remains a viable option, with or without home/hospital support.

Conclusions:

• Long-term outcomes for palliative surgery and transplantation in HLHS infants are not well-established.
• Further research is crucial to define standards of care for HLHS.
• Informed decision-making, considering all options including comfort care, is essential for affected families.
