Background: Aortic root aneurysms are traditionally treated by open surgery methods, which significantly increase the risk of postoperative complications. Elderly patients with a history of previous cardiac surgery have a higher risk of postoperative events and demand more careful supervision during hospitalization. Materials & Methods: We report a case of a 72‐year‐old female patient with aortic root aneurysm and a previous history of cardiac surgery (CABG) with a high risk for EuroSCORE II (15,52%). The postoperative period was uneventful. Discussion and Conclusion: We use this case to discuss the effectiveness and short‐term results of this procedure in patients with high risk. Keywords: aortic aneurysm, CABG, hemiarch reconstruction
