Univentricular heart is a type of congenital heart defect in which the heart has only one ventricle instead of two. This type of heart defect is usually associated with other complex heart defects and can cause serious health problems. Treatment for univentricular heart typically involves surgery to repair the defect and medications to help manage symptoms.

The most common symptoms of univentricular heart include:

-Poor growth and development
-Breathing difficulties
-Cyanosis (blue skin color)
-Fatigue
-Poor feeding
-Poor weight gain
-Heart murmur
-Arrhythmias
-Heart failure
-High blood pressure in the lungs (pulmonary hypertension)

Univentricular heart is a congenital heart defect that occurs when a baby is born with only one ventricle instead of two. The causes of this condition are not fully understood, but it is believed to be caused by genetic and environmental factors. Genetic factors may include chromosomal abnormalities, such as Down syndrome, or mutations in certain genes. Environmental factors may include exposure to certain medications, alcohol, or drugs during pregnancy.

1. Surgery: The most common treatment for univentricular heart is a series of surgeries. The first surgery is a Norwood procedure, which is done in the first few weeks of life. This procedure creates a single pumping chamber out of the two ventricles. The second surgery is a bidirectional Glenn procedure, which is done at around 4-6 months of age. This procedure connects the single pumping chamber to the pulmonary artery and the aorta. The third surgery is a Fontan procedure, which is done at around 18 months of age. This procedure connects the single pumping chamber to the pulmonary veins and the vena cava.

2. Medications: Medications may be prescribed to help manage symptoms of univentricular heart. These medications may include diuretics to reduce fluid buildup, ACE inhibitors to reduce blood pressure,

There is no cure for univentricular heart, but there are treatments available to help manage the condition. These treatments include medications to help manage symptoms, such as diuretics to reduce fluid buildup, and medications to help control the heart rate. Surgery may also be necessary to repair or replace the affected heart valve. In some cases, a heart transplant may be necessary.
