Acute myocardial infarction (AMI) is caused by thrombus formation over a disrupted plaque occluding an epicardial coronary artery. Mechanical thrombectomy is effective in removing thrombus burden from native vessels and saphenous vein grafts. Here we report a case of an aneurysmatic dilatation of an infarct-related artery (IRA) referred to our Institute for rescue PCI, after failed fibrinolysis, successfully treated with only rheolytic thrombectomy (AngioJet, Possis Medical, Minneapolis, Minnesota, USA) without the need for adjunctive balloon or stent implantation.

Mediastinal irradiation can induce coronary artery disease characterized by fibrous lesions developing in the absence of lipid/foam cell accumulation. We document several consecutive cases of acute coronary artery occlusion developing over radiation-induced lesions in patients who were relatively young, without evidence of classical risk factors for atherosclerosis, and in whom the coronary vasculature was otherwise apparently free of disease. The finding of acute coronary artery occlusion at the site of a fibrous lesion lends further support to the hypothesis that acute coronary syndromes may not necessarily be identifiable with ulceration/disruption of the atherosclerotic plaque as the underlying mechanism of acute thrombus formation.

In this paper a new computer aided ECG and VCG data handling is analized. It is based on an optimum estimation of dipole moment, which is used as the main diagnosis parameter. Already known diagnostical methods (available in present literature) are compared with this new technique. The available diagnostical range has been increased widely. The sensitivity of such a program is being analyzed both for normal and abnormal cases.
