Abstract :

Introduction: The echocardiography has an essential place in the surveillance of prostheses. The aim of our study was to describe the clinical and echocardiographic aspects of dysfunction of valvular prostheses. Materials & Methods: This is a retrospective study, which included all patients admitted for dysfunction of mechanical prosthesis double fin in the cardiology department of Marrakech during a period of 2 years. Results: We included 11 patients. Seven cases were carrying a mitral prosthesis, 3 patients with aortic prosthesis and one case a double valve. The average age of prostheses was 3.7 years. The prosthesis dysfunction was revealed by an infectious syndrome (27%), acute heart failure (18%), ischemic stroke (18%), while 36% were asymptomatic. The transthoracic echocardiography (TTE) was pathological in 10 cases: A reduction in the functional surface prostheses with increased transprosthetic gradient (54%) significant paraprosthetic leak (45%), a thrombus in one case, an anomaly of the movements of fins (18%). The echo-transesophageal (TEE) made in 8 patients, objectified images of thrombi (3 cases), paraprosthetic leaks (6 patients), abnormal of the movements of fins (4 cases). Conclusion: Echocardiography is the gold standard for the diagnosis of prosthetic dysfunction with superiority of TEE over TTE.
