Hypoplastic left heart syndrome (HLHS) is a rare congenital heart defect in which the left side of the heart is severely underdeveloped and incapable of supporting the systemic circulation. [2] It is estimated to account for 2-3% of all congenital heart disease. [ 3 ]
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.
William Imon Norwood Jr., also Bill Norwood (April 21, 1941 – December 13, 2020), was an American pediatric cardiac surgeon and physician. He was known for the Norwood procedure, a pioneering cardiac operation named after him for children born with Hypoplastic left heart syndrome.
4-year-old who received new heart after waiting 1,025 days goes home from hospital. According to Cleveland Clinic Children's, John-Henry was born with hypoplastic left heart syndrome, or HLHS, a ...
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]
Collins, 31, tells PEOPLE that he was born with hypoplastic right heart syndrome, which means he was missing a right ventricle. By the time he received the transplant, he had about 10 heart surgeries.
The Fontan Kreutzer procedure is used in pediatric patients who possess only a single functional ventricle, either due to lack of a heart valve (e.g. tricuspid or mitral atresia), an abnormality of the pumping ability of the heart (e.g. hypoplastic left heart syndrome or hypoplastic right heart syndrome), or a complex congenital heart disease where a bi-ventricular repair is impossible or ...
[1] [2] It is used to repair defects that result in the physiology of hypoplastic left heart syndrome even though both ventricles are functioning normally. These defects are common in DiGeorge syndrome and include interrupted aortic arch and LVOT obstruction (IAA/LVOTO); aortic atresia - severe stenosis with ventricular septal defect (AA/VSD ...
