[Surgical repair of pseudoaneurysms with complete atrioventricular block after aortic valve replacement; report of a case].

Aortic pseudoaneurysm is a late complication after cardiac surgery. The patient was a 63-year-old female who had undergone aortic valve replacement 3 years before. She complained of syncope and underwent pacemaker implantation for complete atrioventricular block. Aortic root pseudoaneurysms were accidentally detected by computed tomography, and 1 of them was 50 mm in size. She underwent aortic root replacement with a modified Bentall technique. Although there was no definite infection or inflammation, careful follow-up was considered to be mandatory.
