Between January, 1977, and March, 1990, 84 consecutive patients underwent graft replacement of an ascending aortic aneurysm. There were 22 women and 62 men patients, ranging in age from twenty-two to sixty-nine years (mean 44.3). Surgical procedures employed were as follows: composite graft replacement with coronary reimplantation in 53 cases, supracoronary graft replacement (SGR) in 23 cases, SGR + aortic resuspension in 2 cases, and SGR + aortic valve replace ment in 1 case. Twenty-eight patients (33%) underwent concomitant aortic arch replacement. Five cases were operated on by "elephant-trunk" technique for extensive aneurysms involving the ascending, arch, and descending thoracic aorta. In 71 cases, a shunt was inserted between the periprosthetic space and the right atrium.

Hospital (thirty-day) mortality was 15.5%. Contemporary (1987-1990) mortality rate was 8.7%. After a mean follow-up period of 42.6 months (range three to one hundred eighteen), there were 2 late deaths (1.1%/patient-year). Late reoperation was necessary in 2 cases (1.1%/patient-year). Ninety-one per cent of the survivors were in NYHA class I or II. The long-term survival rate was 76% ± 12%. The type of operation (ie, composite graft replacement or SGR) or concomitant aortic arch replacement had no influence on surgical outcome. The periprosthetic right atrial shunt was found to be effective in avoid ing complications related to blood accumulating between the aortic graft and the aortic wraparound.
