Left ventricular systolic function in dogs with pulmonic stenosis [PDF]

open access: yesVeterinary World, 2020
Background and Aim: Pulmonic stenosis (PS) is the most common congenital heart disease in dogs. This condition causes right ventricle (RV) overload and disrupts overall systolic function.

Will the real ventricular architecture please stand up? [PDF]

open access: yes, 2017
Ventricular twisting, essential for cardiac function, is attributed to the contraction of myocardial helical fibers. The exact relationship between ventricular anatomy and function remains to be determined, but one commonly used explanatory model is the ...

Impact of Aortic Stenosis on Myofiber Stress: Translational Application of Left Ventricle-Aortic Coupling Simulation

open access: yesFrontiers in Physiology, 2020
The severity of aortic stenosis (AS) has traditionally been graded by measuring hemodynamic parameters of transvalvular pressure gradient, ejection jet velocity, or estimating valve orifice area.

Higher Ventricular-Arterial Coupling Derived from Three-Dimensional Echocardiography Is Associated with a Worse Clinical Outcome in Systemic Sclerosis

open access: yesPharmaceuticals, 2021
Primary myocardial involvement is common in systemic sclerosis (SSc). Ventricular-arterial coupling (VAC) reflecting the interplay between ventricular performance and arterial load, is a key determinant of cardiovascular (CV) performance.

Cardiac Chamber Quantification by Echocardiography in Adults: Recommendations from the Association of Cardiovascular Surgeons of Ukraine and Ukrainian Society of Cardiology

open access: yesУкраїнський журнал серцево-судинної хірургії, 2020
Fast technology development over the past decade as well as changes in practical echocardiography (EchoCG) lead to have given rise to a need in the update of previous guidelines for cardiac chambers quantification, which was the aim of this publication ...

Thyroid hormone levels within reference range are associated with heart rate, cardiac structure, and function in middle-aged men and women [PDF]

open access: yes, 2013
Background: Triiodothyronine (T3) has many effects on the heart, and marked changes in cardiac function and structure occur in patients with (subclinical) thyroid disease. We investigated whether between-subject variation in thyroid hormone levels within

Describing right ventricular function [PDF]

open access: yesEuropean Respiratory Journal, 2013
In pulmonary hypertension and other conditions, such as acute respiratory distress syndrome and left heart failure, right ventricular dysfunction is a prognostic determinant. Therefore, functional parameters pertaining to the right heart alone,i.e.independent of its loading conditions, should be used to quantify right ventricular disease progression ...

Synergistic Model of Cardiac Function with a Heart Assist Device [PDF]

open access: yes, 2019
The breakdown of cardiac self-organization leads to heart diseases and failure, the number one cause of death worldwide. The left ventricular pressure–volume relation plays a key role in the diagnosis and treatment of heart diseases.

Association of tricuspid annular plane systolic excursion (TAPSE) with survival time in Boxer dogs with ventricular arrhythmias [PDF]

open access: yes, 2015
BACKGROUND: Tricuspid annular plane systolic excursion (TAPSE) is a useful estimate of right ventricular function in humans. Reference intervals for dogs have been generated, but the value of measuring TAPSE in other diseases, or investigating the ...
