Norwood Procedures

Notice: Undefined index: in /var/www/html/model/Concept.php on line 545

A set of surgical procedures performed to establish sufficient outflow to the systemic circulation in individuals with univentricular congenital heart malformations, such as HYPOPLASTIC LEFT HEART SYNDROME, and MITRAL VALVE atresia, associated with systemic outflow obstruction. Follow-on surgeries may be performed and consist of a HEMI-FONTAN PROCEDURE as the stage 2 Norwood procedure and a FONTAN PROCEDURE as the stage 3 Norwood procedure. A complex cardiac surgical procedure done on individuals with univentricular congenital heart malformations to establish sufficient outflow to the systemic circulation. This operation (Norwood procedure stage 1) involves disconnecting the PULMONARY ARTERY from the heart so that the right ventricle can be connected to the AORTA instead, and the creation of an alternative path for the pulmonary blood flow. The new path for arterial blood flow to the lungs is created by a systemic-to-pulmonary arterial shunt such as a MODIFIED BLALOCK-TAUSSIG SHUNT.
