[Bentall operation for the annuloaortic ectasia which merged liver cirrhosis and pericarditis; report of a case].

We report a case of successful aortic root replacement using a stented bioprosthetic valved conduit and pericardiectomy in a patient with liver cirrhosis and constrictive pericarditis. A 72-year-old man treated for alcoholic liver cirrhosis was referred for the aortic regurgitation and dilatation of sinus of Valsalva. He underwent Bentall operation using a stented bioprosthetic valved conduit and pericardiectomy successfully. For patients whose anticoagulation is contraindicated, aortic root replacement using valved conduit with bioprosthesis is useful option. Concomitant pericardiectomy for constrictive pericarditis may provide better long-term results.
