[Complications of myocardial infarction].

Most acute complications of myocardial infarction do not need emergency imaging, since they often result in death prior to hospital admission: ventricular fibrillation and tachycardia, papillary muscle or septal rupture, fissuration and tamponade. Imaging can play a role at distance of the acute phase (papillary muscle dysfunction, false aneurysm, development of a mural thrombus associated to left ventricular apical dyskinesis, with potential embolic complications).
