Long-term results of Bentall and modified Bentall procedure in aortic root replacement

Between 1976 and 1994, sixteen patients who had annulo-aortic ectasia required aortic root replacements. Ten patients had annulo-aortic ectasia and 6 patients had aortic dissections. The operative techniques included Bentall procedure in 6, Cabrol procedure in 3 and Carrel patch procedure in 7. No hospital death was noted, although there were three major late complications and two of them died. First patient having Bentall procedure died from acute myocardial infarction because of the compressed left coronary artery by the wrapping aneurysmal wall. Second patient having Bentall procedure had enlargement of residual false lumen. Third patient having Cabrol procedure developed false aneurysm at the ostial anastomosis and died of cerebral haemorrhage. In contrast, no late complication has been noted in patients having Carrel patch procedure. Although further long-term follow-up is required, our experience suggests that Carrel patch procedure has less late complication.
