On the regional metabolism of beef heart ventricles.
Acta Physiologica Scandinavica, 1973AbstractThe concentrations of some oligoelements (iron, copper, zinc) and electrolytes (calcium, magnesium, potassium) and the activity of the succinate‐cytochrome c reductase system were determined in various regions of the ventricles of beef heart. In the subepicardial layers of the ventricles and in the upper part of the septum a higher content of ...

Heart transplant for the failing ischaemic ventricle
Cardiovascular Surgery, 1996Clinical 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, 2022Despite 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, 2006In 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

The Right Ventricle in Congenital Heart Disease
Cardiology Clinics, 1992An increasing number of children with congenital heart disease are surviving into adulthood, creating new, unusual patients with different physiologic and anatomic problems for the adult cardiologist. This article discusses those lesions affecting primarily the right ventricle.

Fat in the right ventricle of the normal heart
Histopathology, 2005Aims : 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 ...

Regional analysis of the left ventricle of the heart
Computerized Medical Imaging and Graphics, 2006This 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, 1997During 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.

Actomyosin content of rabbit heart ventricle
American Journal of Physiology-Legacy Content, 1964The requirements for quantitative extraction of rabbit cardiac actomyosin were investigated. Extraction of the tissue was carried out at pH 6.5. Under these conditions, precipitation of actomyosin from the soluble tissue extract showed a plateau between pH 6.9 and 7.1.

ANEURYSM OF THE VENTRICLE OF THE HEART
JAMA: The Journal of the American Medical Association, 1941The 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.
