Impaired Dynamic Cerebral Autoregulation in Cerebral Venous Thrombosis [PDF]

Frontiers in Neurology, 2020
Background: Cerebral autoregulation is crucial in traumatic brain injury, which might be used for determining the optimal intracranial pressure. Cerebral venous thrombosis (CVT) is a cerebral vascular disease with features of high intracranial pressure ...

Determining Thresholds for Three Indices of Autoregulation to Identify the Lower Limit of Autoregulation During Cardiac Surgery. [PDF]

, 2021
OBJECTIVES: Monitoring cerebral autoregulation may help identify the lower limit of autoregulation in individual patients. Mean arterial blood pressure below lower limit of autoregulation appears to be a risk factor for postoperative acute kidney injury.

Transfer function analysis of dynamic cerebral autoregulation: A CARNet white paper 2022 update

Journal of Cerebral Blood Flow and Metabolism, 2022
Cerebral autoregulation (CA) refers to the control of cerebral tissue blood flow (CBF) in response to changes in perfusion pressure. Due to the challenges of measuring intracranial pressure, CA is often described as the relationship between mean arterial

Perspective on Cerebral Autoregulation Monitoring in Neonatal Cardiac Surgery Requiring Cardiopulmonary Bypass

Frontiers in Neurology, 2021
The autoregulation of cerebral blood flow protects against brain injury from transient fluctuations in arterial blood pressure. Impaired autoregulation may contribute to hypoperfusion injury in neonates and infants.

Modeling of Cerebral Blood Flow Autoregulation Using Mathematical Control Theory

Mathematics, 2022
A mathematical model of cerebral blood flow in the form of a dynamical system is studied. The cerebral blood flow autoregulation modeling problem is treated as a nonlinear control problem and the potential and applicability of the nonlinear control ...

Cognitive function in late‐stage HFpEF patients with tricuspid regurgitation undergoing transcatheter tricuspid valve intervention

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1323-1330, December 1, 2022., 2022
Abstract Objectives This study evaluates the impact of transcatheter tricuspid valve interventions (TTVI) on cognitive function (CF), quality of life (QOL), and exercise capacity in late‐stage heart failure with preserved ejection fraction (HFpEF) and relevant tricuspid regurgitation (TR).

Review of studies on dynamic cerebral autoregulation in the acute phase of stroke and the relationship with clinical outcome

Journal of Cerebral Blood Flow and Metabolism, 2021
Acute stroke is associated with high morbidity and mortality. In the last decades, new therapies have been investigated with the aim of improving clinical outcomes in the acute phase post stroke onset.

Comparison of Different Metrics of Cerebral Autoregulation in Association with Major Morbidity and Mortality after Cardiac Surgery [PDF]

, 2022
BACKGROUND: Cardiac surgery studies have established the clinical relevance of personalised arterial blood pressure management based on cerebral autoregulation. However, variabilities exist in autoregulation evaluation.
