What is the most common cause of underdevelopment of the left ventricle?
The reason that this occurs is not fully understood. Conditions that limit blood flow from the right to left atrium during fetal development may result in underdevelopment of the left heart. Such conditions may include premature closure of the foramen ovale and fetal heart muscle disease (cardiomyopathy).
Is hypoplastic left heart syndrome considered heart failure?
Hypoplastic left heart syndrome is one type of congenital heart defect. Congenital means present at birth. Because a baby with this defect needs surgery or other procedures soon after birth, HLHS is considered a critical congenital heart defect (CCHD).
What is the survival rate of Hypoplastic Left Heart Syndrome?
It is fatal without surgical intervention and responsible for 25% to 40% of all neonatal cardiac mortality. Studies have shown 1-year survival for HLHS ranges from 20% to 60%,3–9 with relatively stable 5-year, 10-year, and 15-year survival of ∼40%.
What are the symptoms of hypoplastic left heart syndrome?
Hypoplastic left heart syndrome symptoms include: Grayish-blue skin color (cyanosis) Rapid, difficult breathing. Poor feeding. Cold hands and feet. Weak pulse. Being unusually drowsy or inactive.

How are mitral valves formed in hypoplastic left heart syndrome?
The mitral valves is not formed or is very small. The aortic valve is not formed or is very small. The ascending portion of the aorta is underdeveloped or is too small. Often, babies with hypoplastic left heart syndrome also have an atrial septal defect, which is a hole between the left and right upper chambers (atria) of the heart.
Can a person with mononucleosis have an enlarged spleen?
Complications of mononucleosis can occasionally be serious. The spleen is a small organ normally about the size of your fist. A number of conditions, including liver disease and some cancers, can cause your spleen to become enlarged. Mononucleosis may cause enlargement of the spleen.
