title: Phonocardiographic study of sounds produced by a circulatory assist device: report of a patient with a ruptured ventricular system.
abstract: A patient had a ruptured ventricular septum due to an acute anterior myocardial infarction. An aortic balloon pump was inserted and a subsequent phonocardiographic study was made showing inflation and deflation sounds and the diastolic pulse wave generated. This study defines the extra sounds and pulses generated by such a device so that they may be better understood for clinical interpretation.
