We present an interesting case on the management of a traumatic coronary artery fistula in a 39-year-old man who was stabbed by his wife. During emergency sternotomy, left lung and right ventricle injuries were repaired. On the second postoperative day, an acute myocardial infarction of the anterior wall was recognized. Coronary angiography revealed a rare case of a fistula between the left anterior descending coronary artery and the right ventricle of the heart, which was treated by a stent-graft to avoid a re-operation.
