Trauma-induced occlusion of the left anterior descending artery following a snowmobile accident in a man without prior coronary artery disease.

Blunt chest trauma can cause several forms of heart injuries, of which myocardial infarction (MI) is recognized as a rare complication. An unusual case of occlusion of the left anterior descending artery following a snowmobile accident, with two episodes of sustained ventricular tachycardia, is presented here. Management of the occluded artery included angioplasty and stenting, less than 5 h following the trauma. The resultant decreased ejection fraction following the event emphasizes the importance of rapid intervention in the setting of acute MI following nonpenetrating trauma.
