Improvement of left ventricular systolic function after intervention on right ventricular hemodynamics

Annals of Pediatric Cardiology
Background: The importance of right–left ventricular interactions is increasingly recognized in patients with congenital heart disease. Interventions to improve right ventricular volume/pressure overloading may result in improvement of left ventricular ...

Combined pressure and volume loading for left ventricular training in patients with congenitally corrected transposition of the great arteriesCentral MessagePerspective

JTCVS Open
Objective: Patients with congenitally corrected transposition of the great arteries may require left ventricular training before the double switch operation. We evaluated the effects of combined pressure and volume loading.

Structure-based finite strain modelling of the human left ventricle in diastole [PDF]

, 2013
Finite strain analyses of the left ventricle provide important information on heart function and have the potential to provide insights into the biomechanics of myocardial contractility in health and disease. Systolic dysfunction is the most common cause

Norepinephrine and dobutamine improve cardiac index equally by supporting opposite sides of the heart in an experimental model of chronic pulmonary hypertension

Intensive Care Medicine Experimental, 2021
Background Pulmonary hypertension is a significant risk factor in patients undergoing surgery. The combined effects of general anaesthesia and positive pressure ventilation can aggravate this condition and cause increased pulmonary blood pressures ...

Perfusion of the interventricular septum during ventilation with positive end-expiratory pressure (PEEP) [PDF]

, 1991
Objective: To determine whether regional hypoperfusion of the interventricular septum occurs during ventilation with positive end-expiratory pressure. Design: Animal study. Animals: Anesthetized, closed chest dogs (n = 8).

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

, 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 ...

Left ventricular end‐diastolic pressure in evaluating left ventricular function [PDF]

Clinical Cardiology, 1981
AbstractThere are several factors that could affect the left ventricular end‐diastolic pressure. These include heart rate, preload, afterload, pericardial or pleural pressure, diastolic properties of the left ventricle, and the left ventricular inotropic state.

Portable Low‐Field Magnetic Resonance Imaging in People With Human Immunodeficiency Virus

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The aging population of people with HIV (PWH) raises heightened concerns regarding accelerated aging and dementia. Portable, low‐field MRI (LF‐MRI) is an innovative technology that could enhance access and facilitate routine monitoring of PWH.
