Abstract :Objective: Approximately 20% of all Ischemic strokes are the result of an embolus originating from the heart. Transthoracic echocardiography insert ignore into journalissuearticles values(TTE); has long been used to evaluate the cardiac source of emboli but recently transesophageal echocardiography insert ignore into journalissuearticles values(TEE);, which has higher yield for detecting left atrium, aortic arch and left atrial appendage lesions, Is recommended for the assessment of patients with clinical risk factors for cardioembolism or unexplained stroke. Methods: In this study, the diagnostic yield of TTE and TEE for detecting potential cardiac sources of the embolus was compared in 46 consecutive patients insert ignore into journalissuearticles values(26 men and 20 women, aged 23-84 years); with transient ischemic attack insert ignore into journalissuearticles values(TIA); or acute ischemic stroke. Results: TTE revealed a potential cardiac source of embolism in 12 insert ignore into journalissuearticles values(26%); patients, all of whom had clinical evidence of heart disease, TEE detected potential cardiac sources of embolism in 32 insert ignore into journalissuearticles values(69%); patients; 7 insert ignore into journalissuearticles values(21%); of these had no clinical evidence of heart disease. Conclusion: TEE is a superior technique to TTE for identifying potential cardiac source of the embolus and should be recommended for early management and prevention of further stroke in patients with underlying heart disease or unexplained cerebrovascular accident. Key Words: Ischemic stroke, Transthoracic echocardiography, Transesophageal echocardiography, Cardiac source of embolism.
