				        	Objective To evaluate the safety and efficiency in aortic root disease .Methods From April 2017 to April 2018,46 cases of aortic root disease accepted DavidⅠ[20 cases, 15 males and 5 females, aged(39.6 ±15.8)years, aortic root diameter was(58.3 ±4.4)mm] or Bentall[26 cases, 22 males and 4 females, aged(50.8 ±12.6)years,aortic root diam-eter was(59.5 ±5.0)mm], the data in the peri-operation and heart function in recent period after operation.Results No mortality was observed in the study.Morbidity occurred in both group was comparable.Mean cross-clamp time(129.5 ±28.6) min vs.(94.3 ±35.3)min(P<0.05).Blood transfusion(342.0 ±476.4)ml vs.(330.8 ±651.3)ml(P>0.05).ICU sta-ying time(1.0 ±0.2)day vs.(1.1 ±0.3)day(P>0.05).At the latest visit(10.5 ±6.8)months in David Ⅰ, no obviously regurgitation of aortic valve were observed 0.75 ±0.44 vs 1.0 ±1.3(P>0.05).Conclusion Except for the prolonged cross-clamp time, David Ⅰ is safely and effective in aortic root disease compared with Bentall in peri-operative period .The long term results need further follow-up.
