The local signs of valvular disease may be absent or present. Signs of cardiac enlargement with dilatation of the chambers of the heart are present and may usually be recognized. These phenomena are usually present in varying degrees of severity, in an incompetent heart. When due to intrinsic heart disease a valvula...
The Heart: The heart is one of the first organs that people hear and learn about. It is located in the centre of the chest and must beat continuously throughout a lifetime to keep us alive. Answer and Explanation:1 The four chambers of the heart: ...
However, with a sustained hemodynamic load, maladaptive hypertrophy will proceed, which is associated with dilatation of the heart chambers, accumulation of collagen in the extracellular matrix (interstitial fibrosis), loss of cardiac myocytes (apoptosis), and cardiac dysfunction (Fig. 1). Consequently...
cell death pathways, and heart diseases. By delving into the potential roles of IFI16 in heart pathogenesis, particularly in the context of PANoptosis, we aim to shed light on its multifaceted contributions to disease progression. As the pieces of this puzzle come together, we unveil a new per...
(Physiology) the dilatation of the chambers of the heart that follows each contraction, during which they refill with blood. Comparesystole [C16: via Late Latin from Greek: an expansion, fromdiastelleinto expand, from dia- +stelleinto place, bring together, make ready] ...
1.PhysiologyThe normal rhythmically occurring relaxation and dilatation of the heart chambers, especially the ventricles, during which they fill with blood. 2.The lengthening of a normally short syllable in Greek and Latin verse. [Greekdiastolē,dilation, separation, fromdiastellein,to expand:dia-,...
Aneurysms are persistent, localized dilatations of the vessel wall, classified according to shape or etiology. True aneurysms are formed by the dilatation of the constituents of the vessel wall which exhibits profound structural alterations. In contradis

Non-pathological findings in a pregnant woman include mild dilatation of all four chambers (which may be more marked in the right atrium and ventricle), transient trivial mitral regurgitation (MR), physiological pulmonary and tricuspid regurgitation (TR),7 and increases in CO and left and right ...
Atrial fibrillation is a common supraventricular arrhythmia characterized by rapid and irregular electrical activity in the upper chambers of the heart (atria). This arrhythmia can have various etiologies, including structural heart abnormalities, hypertension, heart valve disorders, coronary artery disease ...
