Optical Hemodynamic Imaging of Jugular Venous Dynamics During Altered Central Venous Pressure [PDF]

arXiv, 2020
An optical imaging system is proposed for quantitatively assessing jugular venous response to altered central venous pressure. The proposed system assesses sub-surface optical absorption changes from jugular venous waveforms with a spatial calibration procedure to normalize incident tissue illumination.

Metabolic changes during cardiac regeneration in the axolotl

Developmental Dynamics, EarlyView.
Abstract Background The axolotl is a prominent model organism of heart regeneration due to its ability to anatomically and functionally repair the heart after an injury that mimics human myocardial infarction. In humans, such an injury leads to permanent scarring. Cardiac regeneration has been linked to metabolism and the oxygenation state, but so far,

Practical Aspects of Nontunneled and Tunneled Hemodialysis Catheters

Canadian Journal of Kidney Health and Disease, 2016
Nontunneled hemodialysis catheters (NTHCs) are typically used when vascular access is required for urgent renal replacement therapy. The preferred site for NTHC insertion in acute kidney injury is the right internal jugular vein followed by the femoral ...

Fat embolism in right internal jugular vein: incidental ultrasound finding during internal jugular vein cannulation

The Ultrasound Journal, 2019
Background We report a case study of fat embolism seen on ultrasound at right internal jugular vein during central venous cannulation in a patient diagnosed with fat embolism syndrome. This case demonstrates the importance of ultrasound for evaluation of

Internal jugular vein thrombosis in a warfarinised patient: a case report [PDF]

, 2007
Introduction Internal jugular vein thrombosis (IJVT) is a rare but potentially fatal condition. It usually arises following trauma to the internal jugular vein but is also seen in association with coagulopathies and advanced malignancies as part of a ...

Role for inflammatory markers in predicting right ventricular failure in mechanical assist device recipients

ESC Heart Failure, EarlyView.
Abstract Right ventricular failure (RVF) is a common complication following left ventricular assist device (LVAD) implantation and increases patient morbidity and mortality. Due to the complex and limited understanding of RVF pathophysiology, efforts to prognosticate RVF after LVAD have been challenging.

3D printed realistic finger vein phantoms [PDF]

arXiv, 2023
Finger vein pattern recognition is an emerging biometric with a good resistance to presentation attacks and low error rates. One problem is that it is hard to obtain ground truth finger vein patterns from live fingers. In this paper we propose an advanced method to create finger vein phantoms using 3D printing where we mimic the optical properties of ...

Transthyretin amyloid cardiomyopathy in aortic stenosis patients scheduled for transcatheter aortic valve implantation

ESC Heart Failure, EarlyView.
Abbreviations: TAVI, transcatheter aortic valve implantation; ATTR‐CM, transthyretin cardiac amyloidosis. We aimed to diagnose occult ATTR‐CM in patients with severe aortic stenosis undergoing TAVI using bone scintigraphy. We verified a diagnosis of ATTR‐CM in 8 of 171 (4.7 %) consecutive aortic stenosis patients who underwent TAVI.

Numerical Modeling of Venous Outflow from the Cranial Cavity in the Supine Body Position

Applied Sciences
The hemodynamic relevance of differently located stenoses of the internal jugular veins remains undetermined. It particularly concerns nozzle-like strictures in the upper parts of these veins and stenotic jugular valves located at the end of these veins.
