Illustration depicting the layers of the heart wall including the innermost endocardium. The endocardium (pl.: endocardia) is the innermost layer of tissue that lines the chambers of the heart. Its cells are embryologically and biologically similar to the endothelial cells that line blood vessels. The endocardium also provides protection to the ...
The heart wall’s made up of three layers, the epicardium being the outermost layer, then the myocardium, and then the endocardium, which is the layer that gets inflamed. It turns out that most cases of endocarditis are due to a microbial infection of the endocardium, usually involving the endocardium lining the cardiac valves.
Whatever the case, the heart needs blood, and if we look at the heart wall, there’s three layers—the outermost layer, the epicardium, then the myocardium in the middle, and the endocardium inside the heart. The coronary arteries start up in the epicardium, and then dive down and supply all the heart tissue.
Heart disease symptoms depend on the type and severity of the heart disease but generally may include: ... which involves damage to the heart’s structure, cells, and tissues.
Infective endocarditis is an infection of the inner surface of the heart, usually the valves. [3] Symptoms may include fever, small areas of bleeding into the skin, heart murmur, feeling tired, and low red blood cells. [3] Complications may include valvular insufficiency, heart failure, stroke, and kidney failure. [4] [3]
The endocardial heart tubes derive from the visceral mesoderm and initially are formed by a confluence of angioblastic blood vessels on either side of the embryonic midline. The endocardial tubes have an intimate proximity to the foregut or pharyngeal endoderm .
Infective endocarditis is an infection of the inner surface of the heart (endocardium), usually the valves. [1] Signs and symptoms may include fever, small areas of bleeding into the skin, heart murmur, feeling tired, and low red blood cell count.
This notch is far less evident in cells from the endocardium, and the difference between the endocardium and epicardium are most clearly seen in the right ventricle. In those with Brugada syndrome, these differences are increased, creating a brief period within each cardiac cycle when current flows from the endocardium to the epicardium ...
