Three-dimensional echocardiography in congenital heart disease: a continuum of unfulfilled promises? No. A presently clinically applicable technology with an important future? Yes.

Three-dimensional echocardiography has important clinical applications to congenital heart disease. Such applications include assessment of ventricular volumes, and unique imaging planes and projections of septae and atrio-ventricular and semi-lunar valves. Advances in ultrasound and computer technology will improve the process of three-dimensional echocardiography to continue to bring it to everyday clinical utility application.
