A univentricular heart : tricuspid atresia [PDF]

, 2013
A two-year-three-month-old boy was diagnosed with tricuspid atresia. This condition requires three surgical interventions, of which he has already had two. He has now presented to hospital with shortness of breath.

Mixed Valvular Disease Following Transcatheter Aortic Valve Replacement: Quantification and Systematic Differentiation Using Clinical Measurements and Image-Based Patient‐Specific In Silico Modeling [PDF]

, 2020
Background: Mixed valvular disease (MVD), mitral regurgitation (MR) from pre‐existing disease in conjunction with paravalvular leak (PVL) following transcatheter aortic valve replacement (TAVR), is one of the most important stimuli for left ventricle (LV)

The Right Ventricle in Pulmonary Arterial Hypertension: Disorders of Metabolism, Angiogenesis and Adrenergic Signaling in Right Ventricular Failure

Circulation Research, 2014
The right ventricle (RV) is the major determinant of functional state and prognosis in pulmonary arterial hypertension. RV hypertrophy (RVH) triggered by pressure overload is initially compensatory but often leads to RV failure.

Improving organ dose sparing in left‐sided breast cancer with yaw‐limited volumetric modulated arc therapy: A dosimetric comparison to conventional and intensity modulated radiation therapy approaches

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background To assess the dose‐sparing capabilities of a yaw‐limited volumetric modulated arc therapy (YL_VMAT) beam setup for adjacent organs at risk (OAR) in comparison with 3D‐conventional radiation therapy (3D‐CRT), intensity‐modulated radiation therapy (IMRT) and conventional VMAT for radiation therapy in left‐sided breast cancer patients.

Post-traumatic hypoxia exacerbates neurological deficit, neuroinflammation and cerebral metabolism in rats with diffuse traumatic brain injury

Journal of Neuroinflammation, 2011
Background The combination of diffuse brain injury with a hypoxic insult is associated with poor outcomes in patients with traumatic brain injury. In this study, we investigated the impact of post-traumatic hypoxia in amplifying secondary brain damage ...

Reference Ranges of Fetal Cerebral Lateral Ventricle Parameters by Ultrasonography [PDF]

Revista Brasileira de Ginecologia e Obstetrícia, 2016
Objectives This study was done to evaluate the normal fetal cerebral lateral ventricle dimensions with transabdominal ultrasonography. The atrial width (AW), ventricle-tochoroid measurement (V-C), ventricle-to-hemisphere ratio (VHR), and combined ...

Association of Systemic Arterial Properties With Right Ventricular Morphology: The Multi‐Ethnic Study of Atherosclerosis (MESA)‐Right Ventricle Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundSystemic arterial stiffness is recognized as a major contributor to development of left ventricular dysfunction and failure; however, the relationship of systemic arterial properties and the right ventricle (RV) is unknown.

Pathways Regulating Establishment and Maintenance of Cardiac Chamber Identity in Zebrafish

Journal of Cardiovascular Development and Disease, 2021
The vertebrate heart is comprised of two types of chambers—ventricles and atria—that have unique morphological and physiological properties. Effective cardiac function depends upon the distinct characteristics of ventricular and atrial cardiomyocytes ...

Analysis of Growing Tumor on the Flow Velocity of Cerebrospinal Fluid in Human Brain Using Computational Modeling and Fluid-Structure Interaction [PDF]

arXiv, 2021
Cerebrospinal fluid (CSF) plays a pivotal role in normal functioning of Brain. Intracranial compartments such as blood, brain and CSF are incompressible in nature. Therefore, if a volume imbalance in one of the aforenoted compartments is observed, the other reaches out to maintain net change to zero.

Student Beats the Teacher: Deep Neural Networks for Lateral Ventricles Segmentation in Brain MR [PDF]

Proc. SPIE 10574, 105742U (2 March 2018), 2018
Ventricular volume and its progression are known to be linked to several brain diseases such as dementia and schizophrenia. Therefore accurate measurement of ventricle volume is vital for longitudinal studies on these disorders, making automated ventricle segmentation algorithms desirable.
