Left anterior descending artery occlusion secondary to blunt chest trauma diagnosed by comprehensive echocardiography and coronary angiography.

Blunt chest trauma can cause serious complications, but coronary artery occlusion is rare. In a 19-year-old man, 40 days after a motorcycle accident, comprehensive echocardiography detected left anterior descending artery occlusion and left ventricular dysfunction, which was confirmed by coronary angiography and ventriculography. Echocardiography was also able to confirm restored left anterior descending artery flow and improved left ventricular function after coronary artery bypass grafting.
