Echocardiography in congenital heart disease.

The combination of M-mode and two-dimensional echocardiography provides precise anatomic and helpful functional information for most types of congenital heart defects. Great strides have been made in the past ten years in ultrasound technology and its applications. The examination of the congenitally deformed heart by echo methods is now an intrinsic component of patient evaluation; a remarkable array of important clinical decisions concerning such patients depends, at least in part, on the results of echocardiographic study.
