A 57-year-old man complained of dyspnea, and his echocardiography showed diffuse severe left ventricular dysfunction. Five days after admission and starting the treatment for congestive heart failure, a computed tomography pointed out DeBakey type 1 aortic dissection with a patent false lumen incidentally. The ostium of the left coronary artery was compressed with the false lumen, and this finding was thought to be a cause of development of left ventricular dysfunction. A modified Bentall procedure with bioprosthesis and total arch replacement were performed. The patient was discharged on the 28th postoperative day without any complications.
