Editing Thrombus (section)

===Mural thrombi===
{{Further|Left ventricular thrombus}}
Mural thrombi form and adhere on the inner wall of a large [[blood vessel]] or [[heart chamber]], often as a result of blood stasis.<ref name="Singh" /> They are most commonly found in the [[aorta]], the largest [[artery]] in the body, more often in the [[descending aorta]], and less often in the [[aortic arch]] or [[abdominal aorta]].<ref name="Singh"/> They can restrict blood flow but usually do not block it entirely. Mural thrombi are usually found in vessels already damaged by [[atherosclerosis]].<ref name="Karaolanis"/>

A mural thrombus can affect any heart chamber. When found in the [[left ventricle]] it is often a result of a heart attack complication. The thrombus in this case can separate from the chamber, be carried through arteries and block a blood vessel.<ref name="Singh"/> They appear grey-red with alternating light and dark lines (known as [[lines of Zahn]]) which represent bands of white blood cells and red blood cells (darker) entrapped in layers of [[fibrin]].{{citation needed|date=September 2022}}
