【摘要】Objective To summarize the short and mid-term outcome of adult patient suffered with aortic stenosis and small aortic root treated by aortic root enlargement with supraannular prostheses replacement or supraannular prostheses replace-ment.Methods From January 2005 to January 2017, 223 patients with aortic stenosis and small aortic root who underwent i-solated aortic valve replacement(AVR) were included in this retrospective study cohort.Patients with aortic insufficiency who underwent isolated AVR or those who underwent combined valve replacement were excluded from the study cohort .Aortic root enlargement with supraannular prostheses replacement was performed in 98 patients(ARE), and supraannular prostheses re-placement was performed in the remaining 125 patients as a control group(SP).The mean age and other baseline characteristics were compared between the two group, except that body surface area(BSA) in ARE were higher than that in SP[(1.62 ± 0.04)m2 vs(1.61 ±0.04)m2, P=0.015].Results Operative mortality occurred in 6 patients(2.7%), the cause of death including low cardiac output syndrome(LCOS, 3 patients), multiple
