Epidemiology of Noncomplex Left Ventricular Outflow Tract Obstruction Malformations (Aortic Valve Stenosis Coarctation of the Aorta Hypoplastic Left Heart Syndrome) in Texas 1999 –2001

摘要

BACKGROUNDThe left ventricular outflow tract (LVOT) malformations aortic valve stenosis (AVS), coarctation of the aorta (CoA), and hypoplastic left heart syndrome (HLHS) contribute significantly to infant mortality due to birth defects. Previous epidemiology data showed rate differences between male and female and white and black ethnic groups. The Texas Birth Defects Registry, an active surveillance program, enables study in a large, diverse population including Hispanics.
