Abstract：Objective To compare the clinical efficacy of surgical aortic valve replacement(SAVR)and transcathe-ter aortic valve replacement(TAVR)in the treatment of aortic stenosis(AS).Methods From January 2020 to October 2024,41 patients with severe AS admitted to the Department of Cardiac Surgery,the First Affiliated Hospital of Bengbu Medical University were divided into the TAVR group(15 cases)and SAVR group(26 cases)according to different surgi-cal methods,and patients in the TAVR group were treated with TAVR,SAVR group with SAVR.Left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDD),postoperative mechanical ventilation time,postopera-tive hospitalization time,drainage on the first day after operation,intensive care unit(ICU)stay,and postoperative com-plications were compared between the two groups.Results Compared with the same group before operation,LVEDD and LVEF in the TAVR group,and LVEDD in the SAVR group decreased after operation(all P<0.05).Compared with the SAVR group,LVEDD in the TAVR group decreased after operation(P<0.05).Compared with the SAVR group,TAVR group had less drainage on the first day after operation(P<0.05).Compared with the SAVR group,the postopera-tive mechanical ventilation time,postoperative hospital stay and ICU stay in the TAVR group were shorter,but there were no statistical differences between the two groups(all P>0.05).Postoperative perivalvular leakage occurred in 2 cases(13.33%)in the TAVR group,and 1 case(3.85%)in the SAVR group,meanwhile,2 cases(7.69%)had wound infec-tion and 1 case(3.85%)had hemostasis of reoperation in the SAVR group,with no significant differences between the two groups(all P>0.05).Conclusion TAVR and SAVR are effective in treatment of severe AS,both of which can improve patients'cardiac function,but TAVR has shorter recovery time,less surgical trauma and fewer surgical complications than SAVR.
