What Is HLHS?

Hypoplastic Left Heart Syndrome (HLHS) is a complex congenital heart defect that affects normal blood flow through the heart. This condition is characterized by the underdevelopment of the left side of the heart, which includes the left ventricle, aorta, and mitral valve. As a result, the heart struggles to pump oxygen-rich blood to the body, leading to serious health complications if not treated promptly.

HLHS is typically diagnosed shortly after birth, although some cases may be identified during prenatal ultrasounds. The exact cause of HLHS remains unclear, but it is believed to involve a combination of genetic and environmental factors. This condition occurs in approximately 1 in every 4,000 live births, making it one of the more common congenital heart defects.

Understanding the Heart’s Anatomy

To grasp the implications of HLHS, it’s essential to understand the heart’s anatomy. The heart has four chambers: two atria and two ventricles. In a healthy heart, the left side is responsible for pumping oxygenated blood to the body, while the right side pumps deoxygenated blood to the lungs. In HLHS, the left side is severely underdeveloped, which disrupts this vital function.

Types of HLHS

HLHS can be categorized into several types based on the specific structures affected. The most common type involves:

• Mitral Valve Atresia: The mitral valve is absent or malformed, preventing blood flow from the left atrium to the left ventricle.
• Aortic Atresia: The aorta is either absent or severely narrowed, limiting blood flow to the body.
• Hypoplastic Left Ventricle: The left ventricle is underdeveloped, which compromises its ability to pump blood effectively.

Each type presents unique challenges and requires tailored treatment approaches.

HLHS Symptoms

Recognizing the symptoms of Hypoplastic Left Heart Syndrome (HLHS) is crucial for early diagnosis and intervention. Symptoms can vary depending on the severity of the condition and may not be immediately apparent at birth. However, common signs to watch for include:

Common Symptoms in Newborns

• Cyanosis: A bluish tint to the skin, lips, and nails due to low oxygen levels in the blood.
• Rapid Breathing: Increased respiratory rate as the body struggles to get enough oxygen.
• Weak Pulse: A weak or absent pulse in the arms and legs, indicating poor blood circulation.
• Feeding Difficulties: Infants may have trouble feeding or may tire easily during feeding.
