Ultrasoundcardiographic Studies of the Mitral Valve Region in Young Infants with Mitral Atresia, Mitral Stenosis, Hypoplasia of the Left Ventricle, and Cor Triatriatum

22 young infants, including 12 with congenital heart disease (2 with mitral atresia, 3 with mitral stenosis and aortic valvular atresia, 5 with mitral and aortic valvular stenosis, 1 with cor triatriatum, and 1 with severe aortic valvular stenosis with a normal mitral valve) and 10 infants without heart disease.
