RESUMO
Coronary artery and valvular injuries after blunt chest trauma are an unusual condition. This diagnosis is very difficult to estabilish, but prompt diagnosis and proper management are important in life saving. We report one patient who develop left main coronary artery dissection, tricuspid insufficiency, mitral insufficiency and pericardial rupture following blunt chest trauma. One year ago, he had suffered a frontal impact in a traffic accident and recieved anti-tuberculosis medication for 10 months for chest discomfort. The correct diagnosis was confirmed noninvasively by transesophageal echocardiography and the patient was treated left main coronary artery dissection flap removal, mitral valve replacement, tricuspid valvuloplasty and repair of ruptured pericardium. The postoperative course was uneventful and the patient was fully recovered.
