Why the study?
A digital tool was needed to facilitate emergency intervention and patient follow-up by preprocessing PCG signals from mechanical heart valves.
A novel medical platform utilizing Hilbert-Huang Transform for PCG signal preprocessing provides a digital tool to assist in the monitoring and diagnosis of patients with mechanical heart valves.

May assist PCG monitoring in mechanical valve patients; leaves open prospective clinical validation.
In this work, we present the implementation of a platform for the pre-processing of a PCG signal from a double-winged mechanical heart valve.This platform is essential for the treatment of a patient undergoing a valve replacement operation.This application facilitates the intervention in case of emergency as well as the follow-up of the patient's health condition.Indeed, this approach will help cardiologists and scientific researchers to design a simple, secure, and intelligent digital tool, allowing them to have an additional source of information in the field of digital processing of cardiac signals.Finally, we tested and validated this platform with a cardiac signal from a patient with a blocked valve.
