Bentall operation was performed for the ascending aortic dissection in the patient of a 70-year old man, who had undergone aortic valve replacement (AVR) for aortic valve regurgitation 7 years ago. At the AVR, the diameter of the ascending aorta was 50 mm on CT. ⋯ These situations suggested that the aortic dissection might be occurred just or early after AVR, and the reinforcement of aortotomy using felt-strips and AVR could not prevent progression of aortic root enlargement and dissection. From some previous reports about ascending aortic dissection after AVR, an adequate surgical treatment for a dilated ascending aorta (40-50 min) should be required at the same time of AVR.
