Tetralogy of Fallot
Explanation: BIRTH DEFECT RISK FACTOR SERIES:
CONOTRUNCAL HEART DEFECTS
Conotruncal heart defects are also known as outflow tract defects. Common types of conotruncal heart defects are truncus arteriosus, transposition of the great arteries, double outlet of the right ventricle, and tetralogy of Fallot. In truncus arteriosus, also known as common truncus, there is a single outflow tract instead of a separate aorta and pulmonary artery. Transposition of the great arteries consists of the great arteries being switched so that the aorta arises from the right ventricle and the pulmonary artery from the left ventricle. In double outlet of the right ventricle, both the pulmonary artery and aorta originate from the right ventricle. Tetralogy of Fallot involves a ventricular septal defect, right ventricular outflow tract obstruction such as pulmonary atresia or stenosis, aorta overriding the ventricular septum, and right ventricular hypertrophy. Other types of conotruncal defects include pulmonary atresia with ventricular septal defect and aortopulmonary window. http://www.tdh.state.tx.us/tbdmd/risk/risk15-conotrncl.htm
