Rivero-Carvallo Sign in Bioprosthetic Tricuspid Valve Stenosis [PDF]

open access: yesJACC: Case Reports, 2023
In a case with bioprosthetic tricuspid stenosis, simultaneous phonocardiogram and Doppler recordings revealed that the louder diastolic rumble in inspiration (Rivero-Carvallo sign) is related to increased tricuspid gradient caused by less prominent ...

Time-frequency scaling transformation of the phonocardiogram based of the matching pursuit method.

open access: green, 1998
International audienceA time-frequency scaling transformation based on the matching pursuit (MP) method is developed for the phonocardiogram (PCG). The MP method decomposes a signal into a series of time-frequency atoms by using an iterative process. The

A multimodal parallel method for left ventricular dysfunction identification based on phonocardiogram and electrocardiogram signals synchronous analysis

open access: yesMathematical Biosciences and Engineering, 2022
Heart failure (HF) is widely acknowledged as the terminal stage of cardiac disease and represents a global clinical and public health problem. Left ventricular ejection fraction (LVEF) measured by echocardiography is an important indicator of HF ...

Phonocardiogram Signal Based Multi-Class Cardiac Diagnostic Decision Support System

open access: yesIEEE Access, 2021
A Phonocardiogram (PCG) signal represents murmurs and sounds signals made by vibrations caused for the period of a cardiac cycle. Acoustic wave generated through the beat of the cardiac cycle propagates through the chest wall.
