Stroke is defined as the rapid loss of brain function due to the disturbance of blood supplied to the brain. Strokes are defined as either ischemic or hemorrhagic. Ischemic strokes, which are the more common type, occur when the blood supply to a portion of the brain is cut off and causes that portion of the brain to cease functioning. Hemorrhagic strokes are caused by bleeding in the brain, and are most often caused by anticoagulation medications.
Strokes caused by blood clots often cause more significant damage due to the size of the clot and the sudden nature of the of the loss of blood supply to the affected area.

- Studies have indicated that over 90% of clots that form in the heart come from the LAA
