echocardiography is a non-invasive diagnostic technique which provides information regarding cardiac function and hemodynamics. it is the most frequently used cardiovascular diagnostic test after electrocardiography and chest x-ray. however, in a patient with acute chest pain, transthoracic echocardiography is essential both for diagnosing acute coronary syndrome, zeroing on the evaluation of v...

Cardiac myxoma is usually a benign tumor in the left atrium that accounts for more than 50% of primary cardiac tumors. A 55-year-old female referred to our hospital with chest pain, referred pain to the left hand, and severe dyspnea. Transthoracic Doppler Echocardiography was performed and the results showed a large and mobile left atrial mass without any attachment to the interatrial septum. I...

A 42-year old male presented with chest pain. Left pneumonectomy had been performed 15 years before for tuberculosis. A chest X-ray showed small left-sided pneumothorax (Fig. 1).

With oxygen supplement, chest pain was relieved and the pneumothora...

The acute occlusion of a coronary artery without the evidence of myocardial infarction might immediately affect both the diagnosis and treatment of coronary artery disease. We present the case with a sudden occlusion of the left main coronary artery without typical chest pain following an exercise tolerance test and rapid spontaneous reperfusion of the left main coronary artery.
