Hybrid endovascular repair of Kommerell diverticulum and aberrant right subclavian artery in a patient with repaired coarctation of the aorta

A 65-year-old Caucasian man was admitted to the Cardiothoracic Department for elective coronary artery bypass graft (CABG). At pre-operative bidimensional transthoracic echocardiography (TTE), a narrowing of the ascending aorta was observed: the inner lumen was reduced by a circumferential, bulky ridge of tissue projecting from the aortic wall and causing a mild supravalvular stenosis (mean PG 20 mmHg) (Figure 1, A-B).
