[Myocardial infarction due to buckshot lodged in the right coronary artery (author's transl)].
A rare case of myocardial infarction produced by a buckshot lodged in the right coronary artery is presented. It resulted from a shotgun blast aimed at the right side of the chest. The patient was admitted to an Intensive Care Unit in a state of shock 1 hour after the accident. The diagnosis was suspected from the first moment because of ECG disturbances and it was later confirmed by coronary angiography. Hemodynamic studies were carried out simultaneously. The patient also presented hemothorax requiring pleural drainage. X-rays revealed a lung contusion with an intraparenchymatous hematoma the whole length of the projectile pathway. During the clinical course a slight hemopericardium was demonstrated by echocardiography; it was originally suspected on the basis of the X-rays. Drainage was not necessary. The patient left the Intensive Care Unit 7 days after entry and was discharged from the Hospital 5 days later. His clinical and hemodynamic condition was good and ECG indicate cicatrization of the myocardial infarction of the diaphragmatic face. The diagnosis and treatment of open or closed traumas of the thorax with similar cardiac involvement in emergency conditions are discussed. The authors prefer not to operate immediately in these cases.
