Abstract
Thirty cases of atrial septal defect proved by cardiac catheterization, surgery, or postmortem examination have been investigated with the technic of intracardiac phonocardiography, which provided precise localization of the source of heart sounds and murmurs. The site and mechanism of origin of the many auscultatory signs in uncomplicated atrial septal defect and in cases of Lutembacher's syndrome, tricuspid atresia, and persistent atrioventricular canal were elucidated by direct intracardiac sound recordings and simultaneous external chest phonocardiograms.
