ACOUSTIC CHARACTERIZATION OF PROSTHETIC HEART VALVES

摘要

We demonstrated that the acoustic signatures of the functioning heart valves provide information as to the condition of the outlet strut. We developed advanced signal processing techniques to extract the acoustic signals and transform those signals into the frequency domain to provide features for classification of the heart valve. Our classification procedures have produced excellent results on a limited number of heart valves. We will increase the confidence in the predictive capabilities of the heart valve classification algorithms as we process additional data.
