Objective: The aim of this study is to assess the mortality and morbidity factors of surgery for ascending aorta aneurysm. Methods: This is a retrospective study of 229 sheet records of patients who underwent ascending aorta replacement for aneurysm; the statistical analyze permitted to assess the mortality and morbidity factors. Results: A replacement of the ascending aorta with the aortic valve (Bentall) was done in 33%, and without replacement of the aortic valve (David) in 15 % of patients. A supra coronary replacement of the aorta was done in 52% of patients while 5 % had the aortic valve not replaced. Preoperative morbidity factors were: addition of medical risk factors, supra coronary replacement of the aorta without replacement of the aortic valve. Post-operative factors were: use of inotropes and long ICU stay. Global mortality, including hospital mortality was 4% (9 patients). The only preoperative factor of mortality was hypothermia and the only post-operative factor decreased ejection fraction. Conclusion: The bad prognosis factors were non treatment of a lesion the aortic valve, ventricular dysfunction and surgery extended to the horizontal aorta.
