Validation of Noninvasive Derivation of the Central Aortic Pressure Waveform from Fingertip Photoplethysmography Using a Novel Selective Transfer Function Method
Autor: James R. Cox, Ehad Akeila, Alberto P. Avolio, Mark Butlin, Catherine Liao, Gisele J. Bentley, Ahmad Qasem
Publikováno v: Pulse, Vol 12, Iss 1, Pp 95-105 (2024)
Introduction: Central aortic pressure waveform analyses can provide clinically relevant information beyond conventional brachial blood pressure (BP) assessment. This waveform can be reproduced noninvasively through application of a generalized transf

Aortic Pressure Control Based on Deep Reinforcement Learning for Ex Vivo Heart Perfusion
Autor: Shangting Wang, Ming Yang, Yuan Liu, Junwen Yu
Publikováno v: Applied Sciences, Vol 14, Iss 19, p 8735 (2024)
In ex vivo heart perfusion (EVHP), the control of aortic pressure (AoP) is critical for maintaining the heart’s physiologic aerobic metabolism. However, the complexity of and variability in cardiac parameters present a challenge in achieving the ra

Discrepancy between two invasive blood pressure measurements in patients receiving intra-aortic balloon pump therapy
Autor: Lijuan Lu, Shiyi Zhang, Yu Zhang, Xiaoyan Zhao
Publikováno v: BMC Cardiovascular Disorders, Vol 23, Iss 1, Pp 1-11 (2023)
Abstract Background Hemodynamic monitoring is imperative for patients with cardiogenic shock undergoing Intra-aortic Balloon Pump (IABP) therapy. Blood pressure monitoring encompasses non-invasive, invasive peripheral arterial pressure (IPAP), and in

Publikováno v: Journal of Cardiovascular Magnetic Resonance, Vol 26, Iss 1, Pp 101030- (2024)
ABSTRACT: Background: Ascending thoracic aortic aneurysm (ATAA) is a silent and threatening dilation of the ascending aorta (AscAo). Maximal aortic diameter which is currently used for ATAA patients management and surgery planning has been shown to i

BackgroundUp to one-fifth of patients continue to have poor quality of life after transcatheter aortic valve implantation (TAVI), with an additional similar proportion not surviving 1 year after the procedure. We aimed to assess the value of a new me

Direct estimation of central aortic pressure from measured or quantified mean and diastolic brachial blood pressure: agreement with invasive records
Autor: Daniel Bia, Federico Salazar, Luis Cinca, Marcos Gutierrez, Alvaro Facta, Yanina Zócalo, Alejandro Diaz
Publikováno v: Frontiers in Cardiovascular Medicine, Vol 10 (2023)
BackgroundRecently it has been proposed a new approach to estimate aortic systolic blood pressure (aoSBP) without the need for specific devices, operator-dependent techniques and/or complex wave propagation models/algorithms. The approach proposes ao

Development and characterization of canine‐specific computational models to predict pulsatile arterial hemodynamics and ventricular‐arterial coupling
Autor: Julia C. Hotek, Julio A. Chirinos, Theodore J. Detwiler, Hillary K. Regan, Christopher P. Regan
Publikováno v: Physiological Reports, Vol 11, Iss 11, Pp n/a-n/a (2023)
Abstract Pulsatile hemodynamics analyses provide important information about the ventricular‐arterial system which cannot be inferred by standard blood pressure measurements. Pulse wave analysis (PWA), wave separation analysis (WSA), and wave power
