The embolism from cardiac origin represent the second cause by order of frequency of stroke. Among the accidents of ischemic type, 20 per cent are related to an embolism of cardiac origin and are accessible to an effective prevention thanks to a quick diagnosis of the heart defect. The purpose of our work is to determine the epidemiological profile, clinical, para-clinical heart disease emboligenes and assess their complex support on ground of ischemic stroke in a hospital environment.

We conducted a retrospective study of descriptive type in the cardiology department of the hospital Ibn Rochd of Casablanca during a period of three years (January 2012 -December 2014).

Have been included in our study all patients with this clinical manifestations suggestive of a stroke that the ischemic nature has been confirmed to the brain scanner by a hypodensity with or without flaw. Patients had to be carriers of a proven heart disease high-risk of embolism as defined by the classification TOAST (Total Occlusion Angioplasty Study) and hospitalized during these past three years in the service.

102 exhibited an ischemic heart disease with high risk of embolism giving a prevalence of 9.5 per cent or 48 men and 54 women. There was, overall a predominantly male before 65 years and then a predominantly female from 65 years ago. The peak occurred in the male is located between 55 and 64 years.

The heart disease encountered are: AF (46%) on valve disease, ischemic heart disease (27%), dilated cardiomyopathy (9%).

In the Transoesophageal Echocardiography (TEE), a spontaneous contrast with a thrombus in the left atrial appendage in 4 cases, a dysfunction of pros-theses in 6 cases, an infective endocarditis. The support has been carried out on a case-by-case basis with consultation with the medical team neurological. However, approximately 9% of the cases are complicated by haemorrhage including 5% of deaths.

Stroke is a major complication of heart disease. This work has highlighted the high frequency and the role of cardiac sources of embolism (AF; AF on mitral valve disease, mechanical valve prosthesis; the myocardial infarction,) in the occurrence of a stroke especially Ischemic.

The association of heart disease with stroke is a public health problem in Morocco. The support for this association requires an interdisciplinary collaboration (cardiologists, neurologists, radiologists) and prevention remains the only effective measure.
