Abstract
This report represents a retrospective analysis of the St Vincent''s Hospital (Australia) experience with combined replacement of the aortic valve and ascending aorta using a composite conduit and coronary artery reimplantation, in 44 patients, from 1 January 1981 to 30 June 1988. The mean age at operation was 48 years. Annuloaortic ectasia was the most common indication for operation in 24 patients (54%). There were three hospital deaths (7%). Forty-one patients were discharged from hospital and were followed up for a total of 1106 patient months (mean = 26.5 months). There were three late deaths (7%). One death was due to a new dissection, one to a cerebrovascular accident and one to a drug overdose. So far, no patients have required reoperation. Of the 36 surviving patients available for follow-up, 28 are in New York Heart Association class I, seven patients are in class II and one in class III. Composite graft replacement reduces the risk of recurrent dissection and aneurysm formation and of periprosthetic leak. In the present experience, it is the method of choice in patients with degenerative lesions in the ascending aorta and aortic valve and particularly for annuloaortic ectasia. The exact surgical technique currently used has been the result of an evolution of different techniques.
