biostudies-literatureUnknown7Kanza REHerein, we present a case of a right coronary artery proximal occlusion and acute myocardial infarction with absence of the reverse attenuation gradient sign that was incidentally identified in the emergency room with non-gated computed tomography angiography of the aorta performed to rule out aortic dissection. This case highlights the importance of assessing the heart and coronary arteries even on non-gated computed tomography angiography.European journal of radiology open100245https://www.ebi.ac.uk/biostudies/studies/S-EPMC7352071biostudies-literatureIncidental, non-gated thoracic CT angiographic detection of proximal right coronary artery total occlusion associated with acute myocardial infarction.PMC7352071Bonenfant FAyoub SKanza REfalseIncidental, non-gated thoracic CT angiographic detection of proximal right coronary artery total occlusion associated with acute myocardial infarction.Herein, we present a case of a right coronary artery proximal occlusion and acute myocardial infarction with absence of the reverse attenuation gradient sign that was incidentally identified in the emergency room with non-gated computed tomography angiography of the aorta performed to rule out aortic dissection.
