TL;DR: In this paper, the authors proposed a method for estimating systolic and mean pulmonary artery pressures of a patient, comprising the steps of (a) producing an electric signal xs(t) representative of heart sounds of the patient; (b) extracting second heart sound S2(t), from the signal produced in step (a); (c) extracting pulmonary and aortic components P2t and A2t from S2t; (d) extracting a signal representative of mean cardiac interval; (e) correlating the pulmonary and anaphyric components P

TL;DR: A new energy loss index has the potential to reflect the severity of aortic stenosis better than EOA and is more closely related to the increase in left ventricular workload than Eoa.

TL;DR: EOAproj provides a standardized evaluation of AS severity with DSE and improves the diagnostic accuracy for distinguishing TS and PS AS in patients with low-flow, low-gradient AS.

TL;DR: The application of spectral analysis and the potential of new time-frequency representations and cardiac acoustic mapping to resolve the controversies and better understand the genesis and transmission of heart sounds and murmurs within the heart-thorax acoustic system are reviewed.

TL;DR: Discrepancies between EOA (cath) and EOA(Dop) are largely due to the pressure recovery phenomenon and can be reconciled by calculating ELCo from the echocardiogram.
