Bilateral pulmonary artery banding is considered an option for initial palliation in high-risk patients with hypoplastic left heart syndrome or related anomalies. However, there are potential interim morbidities, including ductal constriction, compromised growth of the ascending aorta, and pulmonary artery stenosis at the banding site. In addition, there are still controversies regarding the optimal timing and choice of the second-stage operation. Between February 2003 and October 2005, twelve high-risk patients with hypoplastic left heart syndrome or related anomalies underwent bilateral pulmonary artery banding. An atrial septal defect was created simultaneously when the septum was intact or the defect was restrictive. After the procedure, intravenous prostaglandin E(1) was continuously administered. The median weight was 3.0 kg (range 1.8-3.6 kg), and the median age was 16 days (range 0-27 days). Atrial septum defect creation was performed simultaneously in two patients. Ten of the twelve patients were discharged from the hospital. One patient died of progressive multiple organ failure and another patient died of cerebral hemorrhage. Eight patients developed various degrees of ductal constriction and required dose adjustment...Continue Reading
Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
