RESUMO
BACKGROUND: Coronary artery aneurysms (CAAs) represent a rare pathology occurring in 1.5%-5% of routine coronary angiograms. Limited data exist on the management of CAA at the time of cardiac surgery. MATERIALS AND METHODS: A single-institution retrospective review was performed on 53 patients who underwent cardiac surgery in the setting of atherosclerotic CAA between 1993 and 2015. Patients were stratified based on treatment strategy: exclusion and distal bypass (n = 26) versus revascularization alone (n = 27). Comparisons were made with respect to mortality, need for further/concomitant interventions, and long-term cardiac function including myocardial infarctions and congestive heart failure. RESULTS: A total of 53 patients underwent cardiac surgery in the setting of CAA disease. Management strategies included ligation and bypass in 26 patients and distal bypass only in 27 patients (with four of the patients in this group undergoing coronary stenting across the aneurysm). There were no significant differences in patient demographics between the two groups. No significant difference was found in either 30-d (P = 0.74) or long-term mortality when exclusion of the CAA was performed compared with revascularization alone (P = 0.20). More exclusion procedures were performed earlier in the experience (median surgical date 2000), whereas revascularization alone predominated later in the experience (median surgical date 2007; P ≤ 0.001). CONCLUSIONS: The practice of CAA exclusion, while still performed in selected cases, has largely been supplanted in patients undergoing revascularization. Exclusion does not appear to offer any advantage over isolated revascularization, supporting the current trends in managing this rare condition.
