Trombus

Thrombus is an aggregation of blood cells in which the blood flow becomes so slow that the blood solidifies. Thrombi may occur anywhere in the body. In this article, only intracardiac thrombi is highlighted. Thrombus is the most common source of cardiac embolism. At least 10-20% of all strokes/TIAs are of cardiac origin. Pulmonary embolism (90-95%) originates in the deep venous system of the lower extremities.
