INTRODUCTION
Motor vehicle accidents are the most common cause of blunt chest trauma
(1). A study showed that 34% of the fatalities resulting from blunt
chest trauma were from thoracic aortic injury and 80% at the crash
scene had mortality from exsanguination into the mediastinum (2). While
myocardial contusion leading to troponin leak is the most common injury
and may lead to impaired ventricular systolic function, valve injury is
rare (3).
