Twisted atrioventricular connections in double inlet right ventricle: evaluation by magnetic resonance imaging [PDF]

open access: yes, 2008
Twisted atrioventricular connections occur almost exclusively in the hearts with biventricular atrioventricular connections. Only one example of double inlet left ventricle has been illustrated in which the axes of the two atrioventricular valves crossed

Altered Oxygen Utilisation in Rat Left Ventricle and Soleus after 14 Days, but Not 2 Days, of Environmental Hypoxia. [PDF]

open access: yes, 2015
The effects of environmental hypoxia on cardiac and skeletal muscle metabolism are dependent on the duration and severity of hypoxic exposure, though factors which dictate the nature of the metabolic response to hypoxia are poorly understood.

Neuroinflammation induced by intracerebroventricular injection of microbial neuraminidase

open access: yesFrontiers in Medicine, 2015
In the present paper we describe the facts that took place in the rat brain after a single injection of the enzyme neuraminidase from Clostridium perfringens into the right lateral ventricle.

Analysis of left ventricular behaviour in diastole by means of finite element method [PDF]

open access: yes, 1979
The human left ventricle in diastole can be modelled as a passive structure with incremental internal pressure change being considered as the load. Recent developments in engineering stress analysis provide techniques for predicting the behaviour of ...

The effect of repolarization duration on the indices of the pump function of the heart ventricles in animals with different types of activation of the myocardium under ectopic excitation of ventricles

open access: yesRussian Open Medical Journal, 2018
Background — The aim of the work was to study the influence of myocardial repolarization on the indices of the pump function in animals with different types of the myocardial activation (dog, amphibians) under ectopic excitation of the ventricles ...

Multimodal Simulation of a Novel Device for a Safe and Effective External Ventricular Drain Placement

open access: yesFrontiers in Neuroscience, 2021
BackgroundExternal ventricular drain (EVD) placement is mandatory for several pathologies. The misplacement rate of the EVD varies widely in literature, ranging from 12.3 to 60%.

Evidence that conflict regarding size of haemodynamic response to interventricular delay optimization of cardiac resynchronization therapy may arise from differences in how atrioventricular delay is kept constant. [PDF]

open access: yes, 2014
Aims: Whether adjusting interventricular (VV) delay changes haemodynamic efficacy of cardiac resynchronization therapy (CRT) is controversial, with conflicting results.

A parallel interaction potential approach coupled with the immersed boundary method for fully resolved simulations of deformable interfaces and membranes [PDF]

open access: yes, 2016
In this paper we show and discuss the use of a versatile interaction potential approach coupled with an immersed boundary method to simulate a variety of flows involving deformable bodies.

Ischemia Enhances the Acute Stretch-Induced Increase in Calcium Spark Rate in Ventricular Myocytes

open access: yesFrontiers in Physiology, 2020
Introduction: In ventricular myocytes, spontaneous release of calcium (Ca2+) from the sarcoplasmic reticulum via ryanodine receptors (“Ca2+ sparks”) is acutely increased by stretch, due to a stretch-induced increase of reactive oxygen species (ROS).
