Acoustic Spectrograms and Detection of Early LVAD Thrombosis

Overview

About this study

The purpose of this study is to characterize the acoustic features of normal left ventricular assist device (LVAD) pump function using spectrography and fast Fourier transformation. The study will also identify abnormalities seen in the acoustic spectrograms of those patients presenting with LVAD thrombosis. Furthermore, the study aims to follow patients where abnormalities are seen in order to ascertain which features are predictive of the development of pump thrombosis and may be considered early markers thereof.
