摘要: CARDIAC rupture is a major cause of mortality after myocardial infarction. 1,2 In small percentage patients, cardiac not catastrophic event, but, rather, results in the formation pseudoaneurysm. Pseudoaneurysm result ventricular contained by adherent pericardium and fibrotic tissue. thus characterized absence tissue its wall relatively narrow ostium between ventricle paraventricular chamber (Fig 1). The plain-film finding paracardiac mass diaphragmatic or posterolateral location 2) conjunction with history previous infarction highly suggestive pseudoaneurysm sufficient indication for angiographic studies. 3,4 Left ventriculography will show filling via ostium. diagnosis confirmed demonstrating an avascular on coronary arteriography. 4 Report Case A 62-year-old man was admitted syncope
