It is defined as a coronary artery dilatation exceeding the diameter of the normal adjacent segment or the diameter of the patient s largest coronary vessel by to 2 times. Coronary artery aneurysms are typically diagnosed by coronary angiography. The prognosis of coronary artery aneurysm is not well known and the management is challenging. Case presentation A 68-year-old Italian-Caucasian man presented to our hospital with angina. Coronary angiography revealed a large coronary aneurysm of the right coronary artery which was successfully treated by the percutaneous implantation of an MGuard stent. Conclusion This case report provides evidence that coronary artery aneurysms even if very large can be safely treated by MGuard stent implantation. We strongly emphasize the high flexibility and good deliverability of this device which leads to the complete exclusion of the aneurysm mediated by the process of endothelization of its thin mesh sleeves. Introduction Coronary artery aneurysm is a rare disorder characterized by an abnormal dilatation diameter 50 of the normal adjacent segments of a localized or diffuse portion of the coronary artery 1 2 . The detected incidence on angiography varies from to in large studies 1 2 . Atherosclerosis is the most common etiology estimated at 50 of cases diagnosed in adults independent of the etiology the aneurysmal segment produces turbulent blood flow with an increased incidence of myocardial ischemic manifestations acute coronary syndromes thromboembolism rupture or .
