Acute Myocardial Infarction Following Right Coronary Artery Dissection due to Blunt Trauma.

Despite the frequent occurrence of blunt chest trauma, associated cardiac injuries are relatively rare. The most common presentation of blunt cardiac injury is benign arrhythmia (e.g., sinus tachycardia), followed in decreasing frequency by increasingly severe arrhythmias and finally physically evident injuries to the heart muscle, the conducting system, cardiac valves, and/or coronary vessels. Here we present an unusual case of a patient who sustained a right coronary artery dissection and associated acute myocardial infarction following a motor vehicle crash.
