DVTs are blood clots that form in the deep veins of the legs or arms. Part of the clot may break off and go to the lung, causing a PE.
Artificial or mechanical heart valves are very useful in replacing heart valves that do not work well. These valves are not a natural part of your body, so clotting can happen on them. If a clot forms and breaks off, a stroke can happen.
The upper heart chambers (atria) beat in a disorganized way and cause rapid, irregular heartbeats. This causes blood to pool, which may allow a clot to form. If these clots break loose, they may travel to the brain and cause a stroke.
