Contrast-enhanced cardiac MRI in blunt chest trauma: differentiating cardiac contusion from acute peri-traumatic myocardial infarction.
Blunt cardiac trauma most commonly manifests as a myocardial contusion. These contusions can cause cardiac enzyme leaks, electrocardiographic abnormalities, and cardiac contractile dysfunction making it difficult to differentiate a myocardial contusion from a peri-traumatic myocardial infarction. We present a case in which delayed contrast-enhanced cardiac magnetic resonance imaging was used to differentiate between contusion and myocardial infarction, leading to conservative management with subsequent complete restitution of myocardial function.
