Intravascular steerable guidewire for fiberoptic laser-heated metal cautery cap in dissolution of human atherosclerotic coronary disease

moment of her hospitalization, there were no hematologic data clearly consistent with ALL, and the chest x-ray film did not reveal lymph nodal enlargement. Therefore echocardiography was initially useful for locating an abnormal mass, leading to a rapid, accurate diagnosis. In fact, in similar cases, the exact diagnosis was delayed with regard to the onset of pericardial disturbances6 The disappearance of the mass after appropriate therapy, documented by echocardiography, is an additional interesting feature. In summary, the characteristic aspects of our case are represented by: (1) the onset of a T-ALL with a cardiac tamponade without signs of the hematologic disease and (2) the possible contribution of ,echocardiography to the diagnosis and follow-up of cases such as ours.
