In Tunisia,although the prevalence of Q fever among blooddonors is high (26%) [1], this disease is rarelydiagnosed. The aim of this study was to describeepidemiological and clinical features of acute Qfever in adults in central Tunisia.PATIENTS AND METHODS

The coronary fistula is a rare abnormality making communicate a coronary artery with a cardiac cavity or a great vessel, so bypassing the myocardial capillary network. The majority of these fistulas are congenital but can nevertheless arise after a cardiac surgery. The right coronary artery and the left anterior descending coronary artery are mostly concerned. The circumflex coronary artery is rarely involved. The most frequent site of drainage is the right ventricle. We report the case of a 2-year-old child, brought by his parents for dyspnoea of effort. The diagnosis of coronary fistula was confirmed by the coronary angiography which showed an aneurysmal circumflex artery, draining into the right ventricle. The intervention was led under cardiopulmonary bypass. We proceeded to the longitudinal opening of the aneurysm then to the blindness of the fistula. The postoperative course was simple.
