Hypoplastic left heart syndrome can be diagnosed prenatally or after birth via echocardiography. Typical findings include a small left ventricle and aorta, abnormalities of the mitral and aortic valves, retrograde flow in the transverse arch of the aorta, and left-to-right flow between the atria.
Hypoplastic left heart syndrome (HLHS) is a rare congenital defect in which a part of the infant's heart is underdeveloped, making it difficult for the left side of the heart to pump enough blood ...
Hypoplastic left heart syndrome, or HLHS, is a congenital heart defect that affects the left side of the heart, specifically affecting the left ventricle and ascending aorta. Also, the aortic valve and mitral valve might be either too small to allow enough blood to flow through, or they might be absent altogether, called atresia.
Jacqueline Anne Noonan (October 28, 1928 – July 23, 2020) was an American pediatric cardiologist best known for her characterization of a genetic disorder now called Noonan syndrome. [ 1 ] [ 2 ] She was also the original describer of hypoplastic left heart syndrome .
Trent has hypoplastic left heart syndrome, or HLHS, a rare congenital birth defect that affects normal blood flow through the heart. “Basically, he was born with half a heart,” Holly Williams ...
Norwood procedure is most commonly performed to treat hypoplastic left heart syndrome, double outlet right ventricle, double inlet left ventricle, and other single ventricle congenital heart defects. [5] Variations are also used for palliation of mitral and tricuspid atresia [6] and subsets of transposition of great arteries (TGA). [7]
A number of genetic conditions are associated with heart defects, including Down syndrome, Turner syndrome, and Marfan syndrome. [3] Congenital heart defects are divided into two main groups: cyanotic heart defects and non-cyanotic heart defects , depending on whether the child has the potential to turn bluish in color. [ 3 ]
By the late 2000s, the procedure was employed in situations where the right ventricle is bigger than the left ventricle and the left ventricle connects to the pulmonary artery instead of the aorta; examples include double inlet left ventricle, TGA with tricuspid atresia and TGA with hypoplastic left heart syndrome.
