Successful surgical treatment of a giant coronary aneurysm communicating with the right atrium.
Aneurysms of the coronary arteries are rare events. In most cases, such abnormalities are clinically silent and, when they cause symptoms, there are dyspnea and/or angina. Our report describes a case presenting with dyspnea; the admission electrocardiogram demonstrated largely spread ischemia in the lower-lateral leads and myocardial necrosis in the inferior wall. Selective coronary angiography disclosed severe three-vessel disease; aortic angiography revealed a large vascular neoformation, partly thrombosed, with multilobes and a wide communication with the ascending aorta; the oxygen run showed a slight, non-significant 'jump' at the level of the right atrium, confirming a possible left-to-right shunt. On open chest surgery, these alterations were confirmed. The principal aneurysm (6-7 cm) originating in right auricle gave rise to a localized pseudoaneurysm above the superior vena cava; the other three aneurysmal structures were situated along the course of the right coronary artery. After 2 years of clinical and echocardiographic control, the patient is symptom-free under conventional medical treatment.
