The Right Ventricle in Congenital Heart Diseases
2014Right 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, 1970IN 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, 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.

Calcium fluxes in frog heart ventricles
Pfl�gers Archiv European Journal of Physiology, 1969Calcium fluxes in frog heart ventricles are determined both during quiescence and during periods of activity. The two main results: (a) calcium influx is much increased by activity; (b) a net release of calcium from the cells occurs immediately after activity, in parallel with, and probably related to, the decline in tension of the downward “staircase”.

Double-chambered left ventricle – a “heart within a heart”
Forensic Science, Medicine and Pathology, 2018A 20-year-old previously well man drowned after performing a back-flip off a bridge into a river. At autopsy no significant injuries or organic illness were identified. An unusual incidental finding was a double chambered left ventricle, or so-called "heart within a heart", with the left ventricle subdivided into two separate chambers by a muscular ...

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.

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 ...

Diastolic shape of the right ventricle of the heart
The Anatomical Record, 1998Knowledge of right ventricular (RV) shape is important to the understanding of RV mechanical function and for the improvement of clinically important RV volume estimation techniques. Refinements to the simplest conceptions of RV shape are presented statistically here, based on a quantitative analysis of three-dimensional magnetic resonance (MR) images ...
