What atherosclerosis findings can CT see in sudden coronary death: Plaque rupture versus plaque erosion.

Sudden death is the most abrupt clinical presentation of acute coronary syndrome. The presence of acute luminal thrombosis is the histopathological hallmark of sudden coronary death. There are 3 main etiologies that can give rise to an acute luminal thrombus: plaque rupture, plaque erosion and, less frequently, eruptive calcified nodules. Coronary computed tomography angiography (CCTA) has the ability to identify high-risk plaque features of coronary artery disease that are associated with future adverse cardiac events. In this report, we illustrate 2 cases of suspected sudden coronary death with a thorough description of how CCTA can be employed to detect high-risk plaque features using histopathology as a gold standard.
