What is Hypoplastic Left Heart Syndrome (HLHS)?

A child born with a rare cardiac condition is known as hypoplastic left heart syndrome (HLHS). It is, therefore, a congenital cardiac defect. In this condition, the left half of the heart is underdeveloped and undersized. Thus, its blood-pumping ability is poor. Instead, blood must be pumped to the lungs and the rest of the body by the right side of the heart, causing severe breathing problems.

What can I expect if my child has hypoplastic left heart syndrome?

  • Your child will require follow-up appointments with a cardiologist (heart doctor) at least once a year for the rest of their life. These checkups guarantee that their lungs, hearts, and other organs still function correctly. An adult congenital heart disease expert will treat your child once they reach adulthood.
  • The majority of kids with hypoplastic left heart syndrome will require cardiac medications. Antibiotics must also be taken before any other procedures, including dental procedures. These medications decrease the risk of endocarditis or heart infection.

What are the Common Symptoms of Hypoplastic Left Heart Syndrome (HLHS)?

Cyanosis is a darkening of the skin, lips, and nails that can be greyish for dark-skinned persons or bluish for light-skinned people.

  • Having trouble breathing.
  • Feeding difficulties.
  • Lethargy, or a lack of vitality.
  • Fast heartbeat.
  • Cold, sweaty, or clammy skin.
  • Weak heartbeat.

If left untreated, this disease might cause a newborn to go into shock.

  • Shock symptoms include cold, clammy skin that may be pale, grey, or blue lips.
  • A weak and rapid pulse.
  • Breathing, which could be shallow and slow or extremely fast.
  • Dull eyes.

Causes, Risk Factors and Complications of Hypoplastic Left Heart Syndrome (HLHS)

Causes

  • A baby's left side of the heart may not fully grow during pregnancy, leading to hypoplastic left heart syndrome (HLHS), which impairs the heart's ability to pump blood to the body.
  • The aorta, left ventricle, and aortic and mitral valves are all impacted by this illness. The ductus arteriosus and foramen ovale allow the right side to pump blood to the body and lungs after birth.
  • Babies with HLHS need medicine to keep their blood flowing until heart surgery since their left side has trouble pumping blood.

Risk Factors

  • The likelihood of having another kid with hypoplastic left heart syndrome (HLHS) or a related condition is increased for those who have a child with this ailment.

Complications

HLHS complications might include:

  • Getting tired more quickly while exercising or playing sports
  • Arrhythmias (irregular heartbeats)
  • Edema is a fluid buildup in the legs, feet, stomach, and lungs
  • Not developing properly
  • Conditions relating to brain and nervous system development
  • More heart surgery or a heart transplant is required

Latest Research and Technologies in the Treatment of Hypoplastic Left Heart Syndrome (HLHS) in Turkey

  • In Turkey, treatment for Hypoplastic Left Heart Syndrome (HLHS) is based on typical staged operations such as the Norwood, Glenn, and Fontan procedures, with ongoing research into stem cell therapy, regenerative medicine, and genetic investigations to improve results.
  • Turkish medical centres significantly contribute to global advances in pediatric cardiology, emphasising improving patient survival and quality of life.

Hypoplastic Left Heart Syndrome (HLHS) Prevention Tips

A lot of HLHS instances lack a clear cause. Nonetheless, healthcare professionals always advise healthy practices throughout pregnancy, such as

  • Avoid smoking and alcohol.
  • Taking care of any illnesses, including diabetes.
  • Consuming a nutritious diet.
  • Taking folic acid as a daily prenatal vitamin

Treatment options for Hypoplastic Left Heart Syndrome (HLHS)

Norwood procedure: The Norwood procedure is a heart surgery performed in the first two weeks of life. It involves rebuilding the aorta, connecting it to the heart, and adding a lung shunt.


Cost Start From USD 18000 - USD 25000Explore Options

Fontan procedure: The Fontan procedure, typically performed in children aged 3-4, involves creating a pathway for oxygen-poor blood to flow directly into the pulmonary arteries, resulting in minimal mixing of oxygen-rich and oxygen-poor blood in the heart.


Cost Start From USD 16000 - USD 27000Explore Options

Heart transplant: A heart transplant is necessary for many infants with hypoplastic left heart syndrome. To prevent their bodies from rejecting the donor's heart, children who have heart transplants must take medications for the rest of their lives.


Cost Start From USD 95000 - USD 170000Explore Options

  • Prenatal Diagnosis:
    • Pregnancy ultrasound: If the infant has HLHS, it may usually be determined by a routine ultrasound examination performed during the second trimester of pregnancy.
  • Postnatal Diagnosis:
    • Echocardiogram: This test creates images of the heart using sound waves.
    • Chest X-ray: An X-ray of your baby's chest can reveal the size and form of their heart and lungs.
    • Electrocardiogram (EKG): An EKG measures a heartbeat's electrical alterations.
    • Pulse oximetry screening: Measures the amount of oxygen in your baby's blood.

A baby with hypoplastic left heart syndrome may receive medication and undergo the following therapies while awaiting surgery or a heart transplant:

  • Breathing help: A ventilator is breathing equipment that can help babies with breathing problems.
  • Feeding tube: A feeding tube can feed babies who struggle to eat or get tired while eating.
  • The ductus arteriosus is kept open by the medication. It typically closes in all babies soon after birth. However, the ductus must remain open in infants with hypoplastic left heart syndrome for blood to flow to the rest of the body.

HLHS can occasionally be detected while the infant is still in the womb during a routine ultrasound. A heart ultrasound, often known as an echocardiogram, or other testing can be performed after birth to confirm the diagnosis.

Although every child's experience is unique, many children with HLHS grow up healthy, though they may require lifelong medical care and cardiac care. Even though they may have heart health or activity issues, some people can still lead normal lives.
