Heart Failure in Humans Reduces Contractile Force in Myocardium From Both Ventricles [PDF]

JACC Basic To Translational Science, 2020
This study measured how heart failure affects the contractile properties of the human myocardium from the left and right ventricles. The data showed that maximum force and maximum power were reduced by approximately 30% in multicellular preparations from

Heart transplant for the failing ischaemic ventricle

Cardiovascular Surgery, 1996
Clinical application of heart transplantation goes beyond 28 years' experience. Ischaemic heart diseases remain, with idiopathic cardiomyopathies, the main indications for cardiac transplant. A combination of haemodynamic, contractile and viability measurements may be useful to choose between transplant and coronary revascularization for the failing ...

Engineering Models of the Heart Left Ventricle

ACS Biomaterials Science & Engineering, 2022
Despite capturing the imagination of scientists for decades, the goal of creating an artificial heart for transplantation proved to be significantly more challenging than initially anticipated. Toward this goal, recent ground-breaking studies demonstrate the development of functional left ventricular (LV) models.

The anatomy of hearts with double inlet ventricle

Cardiology in the Young, 2006
In the past, hearts with double inlet ventricle have been amongst the most contentious of congenital cardiac malformations. This is because, although most examples found with this particular atrioventricular connection have one big and one small chamber within the ventricular mass, for many years the variant most frequently encountered, with a dominant

Fat in the right ventricle of the normal heart

Histopathology, 2005
Aims : Fibrofatty replacement of the right ventricle wall, often with associated inflammation, is the hallmark of arrhythmogenic right ventricular cardiomyopathy (ARVC), a rare but established cause of sudden cardiac death in young adults. Fatty infiltration of the right ventricle alone without fibrosis may also occur but its relation to sudden death ...

ANEURYSM OF THE VENTRICLE OF THE HEART

JAMA: The Journal of the American Medical Association, 1941
The prevalence of coronary occlusion and myocardial infarction as a disease entity has led to widespread interest in this condition, its complications and the sequelae. Among the less common end results of infarct of the heart is the formation of ventricular aneurysm.

The Right Ventricle in Congenital Heart Diseases

2014
Right ventricular function is an important determinant of prognosis and outcome in congenital heart diseases. Right ventricular (RV) adaptation to congenital heart diseases (CHD) has many faces as there is a wide variety in defects involving the right ventricle as well as in treatment strategies.

Adding a Ventricle instead of transplanting a Heart

Nature, 1970
IN heart transplant operations, as practised at present, an unpaired vital organ is excised and another of doubtful viability and doubtful compatibility is substituted. It is no surprise to find that these operations are looked on with some disfavour and have a high mortality rate and poor long term results.

Regional analysis of the left ventricle of the heart

Computerized Medical Imaging and Graphics, 2006
This paper presents a method to analyze the local wall motion of the left ventricle of the heart. Data are sets of points (obtained from various medical imaging modalities) corresponding to surfaces of the left ventricle, which evolve as a function of time.

[Fibrillation of the heart ventricles].

Anesteziologiia i reanimatologiia, 1997
During ventricular fibrillation, extra feedback may form in the myocardial structure due to specific features of such fibrillation, specifically, because of highly asynchronous contractions of some parts of the myocardium; these newly forming feedback is conducive to a persistent development of such arrhythmia.
