Detailed explanation-1: -[6] HLHS can be detected on prenatal sonography between 18 and 22 weeks of gestation with a 4-chamber view of the fetal heart. HLHS carries a poor prognosis with a survival rate reported of 40%–55% after prenatal diagnosis.
Detailed explanation-2: -Diagnosis of HLHS Prenatal ultrasound can identify a problem with the baby’s heart. The diagnosis of HLHS is made by fetal echocardiogram as early as 16 weeks gestation.
Detailed explanation-3: -As a result, the body doesn’t receive enough oxygen-rich blood. In hypoplastic left heart syndrome, the left side of the heart can’t properly supply blood to the body. That’s because the lower left chamber (left ventricle) is too small or isn’t there.
Detailed explanation-4: -Hypoplastic left heart syndrome (HLHS) is a severe congenital heart defect in which the left side of the heart is underdeveloped. In a normal heart, the heart’s left side has the job of pumping oxygenated blood into the aorta, the large artery that carries blood to the body.
