The pericardium (pl.: pericardia), also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. [1] It has two layers, an outer layer made of strong inelastic connective tissue (fibrous pericardium), and an inner layer made of serous membrane (serous pericardium).
The coronary arteries are the arterial blood vessels of coronary circulation, which transport oxygenated blood to the heart muscle. The heart requires a continuous supply of oxygen to function and survive, much like any other tissue or organ of the body. [1] The coronary arteries wrap around the entire heart.
If the effusion is compromising heart function and causing cardiac tamponade, it will need to be drained. [1] Fluid can be drained via needle pericardiocentesis as discussed above or surgical procedures, such as a pericardial window. [2] The intervention used depends on the cause of pericardial effusion and the clinical status of the patient.
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
The deep part of the cardiac plexus is situated in front of the bifurcation of the trachea (known as the carina), above the point of division of the pulmonary artery, and behind the aortic arch.
Hillary Rodham Clinton took a celebratory lap around Washington on Friday, reveling in signs Democrats are coalescing around her White House candidacy.
Interruptions of coronary circulation quickly cause heart attacks (myocardial infarctions), in which the heart muscle is damaged by oxygen starvation. Such interruptions are usually caused by coronary ischemia linked to coronary artery disease , and sometimes to embolism from other causes like obstruction in blood flow through vessels.
[4] [5] Diagnosis is based on the presence of chest pain, a pericardial rub, specific electrocardiogram (ECG) changes, and fluid around the heart. [6] A heart attack may produce similar symptoms to pericarditis. [1] Treatment in most cases is with NSAIDs and possibly the anti-inflammatory medication colchicine. [6]
