Effective hemodynamic monitoring

open access: yesCritical Care, 2022
AbstractHemodynamic monitoring is the centerpiece of patient monitoring in acute care settings. Its effectiveness in terms of improved patient outcomes is difficult to quantify. This review focused on effectiveness of monitoring-linked resuscitation strategies from: (1) process-specific monitoring that allows for non-specific prevention of new onset ...

Non-invasive hemodynamic analysis for aortic regurgitation using computational fluid dynamics and deep learning [PDF]

open access: yesarXiv, 2021
Changes in cardiovascular hemodynamics are closely related to the development of aortic regurgitation, a type of valvular heart disease. Metrics derived from blood flows are used to indicate aortic regurgitation onset and evaluate its severity. These metrics can be non-invasively obtained using four-dimensional (4D) flow magnetic resonance imaging (MRI)

Hemodynamics of hyperuricemia

open access: yesSeminars in Nephrology, 2005
Prolonged hyperuricemia is associated with the development of hypertension, renal arteriolosclerosis, glomerulosclerosis, and tubulointerstitial injury. It confers a greater risk than proteinuria for developing chronic renal disease and is associated with the development of hypertension.

Decompressive Craniectomy for Traumatic Brain Injury: Postoperative TCD Cerebral Hemodynamic Evaluation

open access: yesFrontiers in Neurology, 2019
Background: There are no studies describing the cerebral hemodynamic patterns that can occur in traumatic brain injury (TBI) patients following decompressive craniectomy (DC). Such data have potentially clinical importance for guiding the treatment.

Photoacoustic vector tomography for deep hemodynamic imaging [PDF]

open access: yesarXiv, 2022
Non-invasive imaging of deep blood vessels for mapping hemodynamics remains an open quest in biomedical optical imaging. Although pure optical imaging techniques offer rich optical contrast of blood and have been reported to measure blood flow, they are generally limited to surface imaging within the optical diffusion limit of about one millimeter ...

Transient cerebral hypoperfusion and hypertensive events during atrial fibrillation: a plausible mechanism for cognitive impairment [PDF]

open access: yesScientific Reports, 6: 28635, 2016, 2016
Atrial fibrillation (AF) is associated with an increased risk of dementia and cognitive decline, independent of strokes. Several mechanisms have been proposed to explain this association, but altered cerebral blood flow dynamics during AF has been poorly investigated: in particular, it is unknown how AF influences hemodynamic parameters of the distal ...

Cerebral hemodynamics on MR perfusion images before and after bypass surgery in patients with giant intracranial aneurysms [PDF]

open access: yes, 2001
Preoperative assessment of the anatomy and dynamics of cerebral circulation for patients with giant intracranial aneurysm can improve both outcome prediction and therapeutic approach.

Percutaneous pulmonary valve implantation alters electrophysiologic substrate [PDF]

open access: yes, 2016
BACKGROUND: Percutaneous pulmonary valve implantation (PPVI) is first‐line therapy for some congenital heart disease patients with right ventricular outflow tract dysfunction.

Conducting Polymer Microelectrode Arrays for Simultaneous Electrophysiology and Advanced Brain Imaging

open access: yesAdvanced Functional Materials, EarlyView.
A flexible micro‐electrocorticography array with PEDOT:SS electrodes is shown to be compatible with ultra‐high magnetic field MRI up to 9.4 T. Multimodal brain monitoring is demonstrated by performing simultaneous blood oxygen level‐dependent functional MRI in parallel with electrophysiology.

Randomized preclinical study of machine perfusion in vascularized composite allografts

open access: yesBJS (British Journal of Surgery), EarlyView., 2020
This study was designed to identify the optimum machine perfusion parameters for preservation of limbs before transplantation, and determine whether this was better than cold storage. Normothermic machine perfusion at a pressure of 70 mmHg (NMP‐70) provided superior preservation to cold storage after transplantation.
