Intracardiac phonocardiography, the recording of sounds from within the heart, has been carried out with 63 patients with congenital heart disease. Studies have also been done with 11 patients in the pediatric age range who did not have heart disease. This new technique of recording heart sounds has been shown to provide a degree of localization of heart sounds and murmurs not heretofore obtainable. It is by virtue of this property that intracardiac phonocardiography has an important place in the diagnosis of congenital heart disease. Records from several lesions are shown to illustrate this point.

It is believed that intracardiac phonocardiography should be made a part of the routine studies done at the time of cardiac catheterization.

The prospects for intracardiac phonocardiography are discussed.
