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 ]
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]
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 ...
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 ...
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.
Examples of congenital cardiac malformations in which this procedure may be used include hypoplastic left heart syndrome, tricuspid atresia, double-inlet left ventricle and double-outlet right ventricle. [3] The natural history of congenital univentricular cardiac malformations results in cyanotic heart failure at an early age. Staged ...
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.

The Yasui procedure is a pediatric heart operation used to bypass the left ventricular outflow tract (LVOT) that combines the aortic repair of the Norwood procedure and a shunt similar to that used in the Rastelli procedure in a single operation.
