Cardiogenic embolism can be identified in at least 15% of ischemic stroke patients,
left atrial appendage is believed to be the place where thrombi is performed, then goes to
systemic circulation causing embolic accident .
In this search we study
the function of left atrial appendage by pulse Doppler within
the proximal third of the appendage in patients with ischemic stroke. Thrombus was
defined as a discrete echocardiographically dens mass within the body of atrium or the
appendage, with a different echocardiographically density than the adjacent endothelium .
Spontaneous echo contrast was defined as high density flow due to low flow
condition , which remains stable with changes in gain setting .
In conclusion , the velocities which recorded in patients with ischemic stroke were
lower in comparison with other patients , and it was significant lower in patients with
spontaneous echo contrast or atrial fibrillation .
