[Long-term results of operation in patients with annuloaortic ectasia]

From 1974 to 1990, 24 patients were operated on for annuloaortic ectasia. We chose Bentall's technique for 17 patients with great displacement of coronary ostium, but Cabrol's one for 6 patients since coronary displacement was not great. The hospital mortality was 8.3% (2 deaths). The late mortality has been 5/22 (22.7%). Nevertheless, all the patients employed Cabrol's technique have been free from death, events and reoperation. These results were remarkably better than those of primary isolated AVR. It is considered that poor results were caused not by the operating mode using a composite graft but by the connective tissue disorder as primary pathology of annuloaortic ectasia. We conclude that the patient with annuloaortic ectasia must be observed for a long-term after operation.
