Example of microvascular obstruction after anterior ST-segment elevation myocardial infarction.
Panel A shows a short-axis late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) image of an anterior ST-segment elevation myocardial infarction (STEMI) with microvascular obstruction (MVO). Panel B is the corresponding end-systolic cine frame. Panel C is the long-axis 2-chamberview LGE image of the same patient, showing MVO, and panel D is the corresponding cine frame. MVO is arrowed in all LGE CMR frames. Abbreviations: CMR: Cardiac Magnetic Resonance, LGE: Late gadolinium enhancement, MVO: Microvascular obstruction, STEMI: ST-segment elevation myocardial infarction.
