Objective To assess clinical outcomes of valve-sparing aortic root replacement for patients with aortic root aneurysm.?Methods?From February 2001 to September 2010， sixty patients with aortic root aneurysm underwent valve-sparing aortic root replacement in Fu Wai Hospital. There were 44 male patients and 16 female patients with an average age of 37.2±13.0 years （ranging from 9-64 years）. Fifteen patients had aortic dissection， 10 patients had ascendingaorta aneurysm， 25 patients had Marfan syndrome， and 2 patients had bicuspid aortic valve. Aortic root reconstruction was performed in 53 patients and aortic valve reimplantation was performed in 7 patients. Preoperative and postoperative heart function and degree of aortic insufficiency （AI） were compared.?Results?Valve-sparing aortic root replacement was performed in all patients. There was no in-hospital death or severe postoperative complications in this group. The median duration of mechanical ventilation was 13 hours （ranging from 2 to 1 110 hours） ， while the mean intensive care unit stay was 2.7±2.5 days （ranging from 1 to 18 days） . Postoperative echocardiography showed AI degree was significantly reduced in all the patients. Only three patients had moderate to severe AI， and all the other patients had none or trivial AI. All the patients were followed up for 2-122 （61.5±35.9） months. During follow-up， 4 patients were lost， 9 patients died， and the overall survival rate was 83.9% （47/56）. Two patients underwent aortic valve replacement in the 13 th and 14 th postoperative month respectively because of severe AI. Heart function of 47 patients was significantly improved compared with their preoperative heart function. Thirty-five patients （74.4%）were in New York Heart Association （NYHA） functional classⅠ， and 8 patients （17.0%） were in class II. Forty patients （85.1%）were free from moderate or severe AI.?Conclusion Valve-sparing aortic root replacement has satisfactory long-term outcomes for patients with aortic root aneurysm， and valve-related complication rate is low.
