Introduction : The presence of a high flow of arteriovenous fistula further complicates hemodynamic alterations in patients with terminal renal failure.
Purpose of The Study: To study the heart disease in  chronic hemodialysis patients and to objectively the characteristics of those with an arteriovenous fistula in highflow.
Patients and Methods: an observational study; descriptive; analytical work carried out in collaboration between the two departments of cardiology and nephrology of the university hospital of Marrakech over a period of 6 months including chronic hemodialysis patients who have benefited from a doppler echo of arteriovenous fistula objecting an highflow and transthoracic echocardiography.

Results: 15 patients were pooled with arteriovenous fistula highflow (27.2% of chronic hemodialysis patients at the University Hospital Hemodialysis Center). The mean age was 50.4+/-15.08 years. Hemodialysis age was an average of 5.5+/- 5.01 years. 53.3% were hypertensive; 26.7% were diabetic. This is a brachiocephalic fistula in 80% of cases. The hemodialysis session was uneventful in 53.3% of cases. A heart failure table was objectified in 26.7% of cases. An aneurysmal appearance of arteriovenous fistula was found in 46.7% of cases. Fistula output averaged was 2.4 +/- 0.6 l/min. Left ventricular hypertrophy was found in 60% of cases; cardiac output averaged was 8.4+/- 3.7/min and pulmonary hypertension was found in 33.3% of cases. 

Conclusion: Heart failure is a serious complication of a highflow arteriovenous fistula. The reduction of arteriovenous fistula does not compromise the adequacy of dialysis, hence the need for careful selection of appropriate patients and techniques to act in a timely manner to delay cardiovascular complications.
