Simultaneous acute occlusion of right and anterior descending coronary arteries in acute myocardial infarction

摘要

To the Editor: Acute ST segment elevation myocardial infarction (STEMI) is usually caused by the abrupt complete occlusion of a single epicardial coronary artery due to rupture or erosion of an unstable coronary atherosclerotic plaque. Simultaneous acute total occlusion of more than one epicardial vessel is quite rare and it has been described in only a few cases in the current literature; it is always life threatening because of rapid hemody-namic deterioration leading to cardiogenic shock. The incidence of simultaneous occlusion of more than one major coronary arteries is not known and, to our knowledge, the most numerous series (five cases) reported in the literature is the one by Maagh et al.
