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 ...

Sodium-Hydrogen Exchanger Isoform-1 Inhibition: A Promising Pharmacological Intervention for Resuscitation from Cardiac Arrest

open access: yesMolecules, 2019
Out-of-hospital sudden cardiac arrest is a major public health problem with an overall survival of less than 5%. Upon cardiac arrest, cessation of coronary blood flow rapidly leads to intense myocardial ischemia and activation of the sarcolemmal Na+-H ...

Ventricular interdependence in critically ill patients: from physiology to bedside

open access: yesFrontiers in Physiology, 2023
The review focuses on the mechanism of ventricular interdependence, a frequently encountered phenomena, especially in critically ill patients. It is explained by the anatomy of the heart, with two ventricles sharing a common wall, the septum, and nested ...

Evaluation of myocardial contraction fraction in transcatheter aortic valve replacement

open access: yesHeart Vessels and Transplantation, 2023
Objective: Myocardial contraction fraction (MCF), a costless, easy-to-perform echocardiographic measure, which estimates cardiac function through the volumetric measurement of myocardial shortening, may be a useful prognostic indicator in patients ...

BDNF contributes to the skeletal muscle anti-atrophic effect of exercise training through AMPK-PGC1α signaling in heart failure mice

open access: yesArchives of Medical Science, 2018
Introduction Exercise training is a coadjuvant therapy in preventive cardiology, and it delays cardiac dysfunction and exercise intolerance in heart failure (HF).

The tricuspid valve in hypoplastic left heart syndrome: Echocardiography provides insight into anatomy and function

open access: yesFrontiers in Pediatrics, 2023
Tricuspid regurgitation (TR) is commonly seen in surgically palliated patients with hypoplastic left heart syndrome, and when significant, is associated with an increase in both morbidity and mortality.

The Variation in the Diastolic Period with Interventricular Septal Displacement and Its Relation to the Right Ventricular Function in Pulmonary Hypertension: A Preliminary Cardiac Magnetic Resonance Study

open access: yesDiagnostics, 2022
Background: Pulmonary hypertension (PH) is known to alter the biventricular shape and temporal phases of the cardiac cycle. The presence of interventricular septal (IVS) displacement has been associated with the severity of PH.

The Functional Anatomy of Ventricular Contraction [PDF]

open access: yesCirculation Research, 1953
Changes in dimensions of the ventricular chambers and the displacement of specific points on the walls of the heart have been studied by the cinefluorographic technic. The contributions of the various myocardial layers to ventricular ejection have been considered in terms of the anatomic architecture of the heart.
