We report a case of coronary artery and aortic root aneurysms in a 50-year-old man with Marfan syndrome. The coexistence of these findings is uncommon and rarely reported. We underline the role of electrocardiographically gated computed tomography angiography in the diagnosis of coronary aneurysm in this category of patients.

| Introduction|| |
Coronary artery aneurysm is an uncommon finding, often clinically silent, whose correct diagnosis may prevent severe sudden cardiac events. The use of electrocardiographically (ECG) gated during computed tomography (CT) angiography is an indispensable technical requirement for the identification of these findings and should always be used in the follow-up of this category of patients.
| Case Report|| |
We present the case of a 50-year-old man who referred to the emergency department with sudden chest pain at rest. His blood pressure was 95/60 mmHg. The patient suffered from Marfan syndrome and he was followed in our Department of Clinical Medicine for some years. Routine blood, including cardiac enzymes, and urine analyses were within normal ranges, except C-reactive protein (252 mg/L) and erythrocyte sedimentation rate (84 mm/h). The patient was hospitalized in our cardiology unit and a CT of thorax was request. We chose to subject the patient to a CT angiography “Dual Source” ECG–synchronized to have an optimum viewing of aorta and coronary arteries. The CT scan identified a known aortic root dilatation (44 mm), it excluded the presence of coronary stenosis, but it also allowed finding an important new finding: a right coronary artery aneurysm (8 mm), in the middle and proximal tract, with craniocaudal extension of 4 cm [Figure 1]. Following heart surgeon consulting, according to the characteristics of the aneurysm and in absence of coronary thrombosis, surgical or interventional treatment of the aneurysm were deprecated. In addition to medical therapy with beta-blockers, we decided to treat our patient with aspirin.

| Discussion|| |
Our case confirms the importance of performing an ECG-gated CT, often not used and underestimated, to study pathologies of the thoracic aorta. In particular, in patients with Marfan syndrome, the clinical symptoms are sometimes caused by coronary disease rather than great vessels disease. We recommend as reported in the literature and in the most modern guidelines ,, to always perform, when it is possible, an ECG-gated CT of thoracic aorta to avoid unpleasant consequences which a late diagnosis or a not diagnosis can lead.
