title: Long-term follow-up of coronary artery dissection due to blunt chest trauma with spontaneous healing in a young woman.
abstract: We report a previously healthy 17-year-old woman who experienced coronary artery dissection with an acute transmural anterior myocardial infarction and myocardial contusion following blunt chest trauma in a motorcycle accident. A chest roentgenogram on admission was normal, and an electrocardiogram showed an acute transmural anterior myocardial infarction with complete right-bundle-branch block. A 2D echocardiogram revealed an akinesis of the anterior wall and a hypokinesis of the posterior wall in the left ventricle. Initial coronary angiography demonstrated severe stenosis with delayed antegrade filling in the proximal left anterior descending artery. Technetium-99m pyrophosphate myocardia scintigraphy demonstrated diffuse tracer uptake in the left ventricular wall. Follow-up coronary angiography performed 1 year after the accident showed a minor stenosis without any filling defects. We describe long-term follow-up of the coronary artery dissection following blunt chest trauma with spontaneous healing.
