Chronic disease of the ascending aorta. Surgical treatment and long-term results.
Between January 1979 and December 1991, we operated on 339 patients for chronic disease of the ascending aorta. The operation was elective in all. Endocarditis and its sequelae have been excluded. Thirty-one patients had a previous operation on the ascending aorta or the aortic valve; 268 patients had aneurysms of the ascending aorta without dissection; 72 had chronic aortic dissections, of whom 33 had a preexistent aneurysm. The patients included 272 men and 67 women. Mean age was 53.58 +/- 7 years. Eight percent of the patients had clinical stigmata of Marfan's disease. A tubular graft replacement was used in 7 patients, a tubular graft and valve replacement in 72 patients, and a composite valve graft replacement with reattachment of the coronary arteries using a 8 mm Dacron graft was performed in 260 patients. Concomitant procedures were used in 74 patients: coronary artery bypass grafts in 25, mitral valve replacement in 9, and aortic arch reconstruction in 40. The 30-day mortality rate was 7.6% (n = 26). For the whole group, multivariate analysis using stepwise logistic regression showed that operative risk factors were concomitant coronary artery bypass grafting, age (increased), aortic valve regurgitation, and previous cardiac surgery. Follow-up was conducted in 303 patients, and risk factors for late mortality were studied. Long-term survival was 59.6% +/- 3.7% at 9 years. It was 67% +/- 3.5% at 9 years for patients without aortic arch reconstruction and 56% +/- 4.5% for patients with aortic arch reconstruction (p = 0.0018). Reoperation was needed in 14 patients. Actuarial freedom from reoperation was 90% +/- 0.2% at 9 years for all the patients. Only one patient with composite valve graft replacement and reattachment of the coronary arteries had required reoperation for problems related to this procedure. This technique is used routinely by our team, especially in patients with large chronic aneurysms, dissected or not, and in those who had previous operations. The long-term results are good.
