It has been demonstrated that intracardiac phonocardiography provides precise localization of the source of cardiovascular sounds. Can this technic be of practical help in the diagnosis of small or complicated ventricular septal defects? Is a ventricular septal defect ever silent? What mechanisms are responsible for the diastolic murmurs in ventricular septal defect? In an attempt to answer these problems, intracardiac phonocardiograms have been studied in 47 cases.
