Summary
Ultrasoundcardiography (UCG) studies have been performed in about three hundred children. The age of the children varied between 1 day and 16 years. Most of the studies have been performed without premedication and all without discomfort.
The UCG‐technique has been found valuable for demonstration of dilatation of the right ventricle both in cyanotic and acyanotic congenital heart disease. In studies of lesion affecting the tricuspid valve pathological UCG‐findings have been obtained in patients with tricuspid atresia and Ebsteins anomaly.
The method has also been found useful in evaluation of the state of the mitral valve. Pathological findings have been obtained in congenital mitral stenosis, mitral atresia and other forms of hypoplastic left heart syndrome, in endocardial cushion defects and in mitral regurgitation.
The UCG‐technique also provides information about the outflow tract of the left ventricle. Pathological findings have been obtained in cases with membraneous subvalvular aortic stenosis and hypertrophic obstructive cardiomyopathy.
Pericardial effusion and thrombosis in the right atrium may be demonstrated by this technique. No complications have been observed.
In the early 1950's, research was started at the University of Lund on the use of ultrasound as a diagnostic tool in cardiology, neurology, and gynecology. The results of this work provided impetus for the later development of the ultrasonic echo method into a routine procedure in many fields of medicine. A historical review of this fundamental work is given in this paper which also stresses the importance of a stimulating and free atmosphere for the development of new ideas in research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
