Minimal invasive extracorporeal circulation an alternative to ECMO in ventricular tachycardia ablation

open access: yesThe Journal of ExtraCorporeal Technology, 2023
Background: The advantages of mechanical assistance during ventricular tachycardia (VT) ablation have not been clinically demonstrated. We propose and discuss a technique, set up by us, that makes use of minimally invasive extra-corporeal circulation ...

Physiology and prevention of heel ulcers: The state of science [PDF]

open access: yes, 2003
The prevalence of heel ulcers across settings is high and is increasing. Prevention of ulcers requires knowledge of their etiology and the scientific basis for preventive care. The interaction between external pressure and the heel vasculature is central

Inhibition of Trophoblast-Induced Spiral Artery Remodeling Reduces Placental Perfusion in Rat Pregnancy. [PDF]

open access: yes, 2010
Rats harboring the human angiotensinogen and human renin genes develop preeclamptic features in pregnancy. The preeclamptic rats exhibit a deeper trophoblast invasion associated with a reduced resistance index by uterine Doppler.

Mild hyperthermia enhances sensitivity of gastric cancer cells to chemotherapy through reactive oxygen species–induced autophagic death

open access: yesTumor Biology, 2017
Mild hyperthermia enhances anti-cancer effects of chemotherapy, but the precise biochemical mechanisms involved are not clear. This study was carried out to investigate whether mild hyperthermia sensitizes gastric cancer cells to chemotherapy through ...

Prediction of final infarct volume from native CT perfusion and treatment parameters using deep learning [PDF]

open access: yes, 2019
CT Perfusion (CTP) imaging has gained importance in the diagnosis of acute stroke. Conventional perfusion analysis performs a deconvolution of the measurements and thresholds the perfusion parameters to determine the tissue status.

Indexed oxygen delivery during pediatric cardiopulmonary bypass is a modifiable risk factor for postoperative acute kidney injury

open access: yesThe Journal of ExtraCorporeal Technology, 2023
Background: Acute kidney injury after pediatric cardiac surgery is a common complication with few established modifiable risk factors. We sought to characterize whether indexed oxygen delivery during cardiopulmonary bypass was associated with ...

Myocardial perfusion [PDF]

open access: yesJournal of Magnetic Resonance Imaging, 2006
AbstractNoninvasive cardiac magnetic resonance (CMR) imaging has progressed rapidly over the past few years and will most likely become an integral part of the diagnostic workup of patients with known or suspected coronary artery disease (CAD). In this article the rationale for using perfusion‐CMR is discussed, followed by a summary of current state‐of‐

High pressure excursion in a radial design oxygenator

open access: yesThe Journal of ExtraCorporeal Technology
Oxygenator high-pressure (HPE) is a phenomenon that can occur during cardiopulmonary bypass (CPB) in which the oxygenator inlet pressure increases rapidly, thereby limiting flow. Most perfusionists globally do not use inlet oxygenator pressure monitoring

Usefulness of a visual aid in achieving optimal positioning for spinal anesthesia: a randomized trial

open access: yesBMC Anesthesiology, 2018
Background Optimal patient positioning is perceived as an essential factor to increase the success of performing neuraxial blockade. The primary objective of this study was to evaluate the benefit of using a visual image in addition to verbal ...

Impaired coronary blood flow at higher heart rates during atrial fibrillation: investigation via multiscale modelling [PDF]

open access: yes, 2019
Background. Different mechanisms have been proposed to relate atrial fibrillation (AF) and coronary flow impairment, even in absence of relevant coronary artery disease (CAD). However, the underlying hemodynamics remains unclear.
