Trans-catheter versus open surgical aortic valve replacement in severe symptomatic aortic stenosis

Abstract

The objectives of this study were: (1) to compare the incidence of effective orifice area (EOA) after either the trans-catheter and surgical aortic valve replacement (SAVR); and (2) to assess the impact of EOA on life style modifications and mortality recorded after either surgical or trans-catheter aortic valve replacement. Trans-catheter aortic valve replacement (TAVR) has emerged as a valid alternative to SAVR in selected patients. It appears important to implement preventive strategies to avoid prosthesis failure without increasing operative risk. A case series of 148 consecutive patients from January 2023 to January 2025 with severe aortic valve stenosis. The patients were randomized into two groups as trans-catheter aortic valve replacement (TAVR as group A) and surgical aortic valve replacement (SAVR as group B). The Echocardiography was done pre- and postoperatively, plus scales of life activities in the follow-up period (6 months and one year). In this study, a total of 148 patients were studied to determine the outcomes of patients who underwent either trans-catheter or surgical aortic valve replacement in terms of demographic, operative, and postoperative variables. There were significant improvement in Echo findings after 6 months and one year. In the other side, there were no significant differences comparing both groups according to quality of life parameters. In patients with severe aortic stenosis and high surgical risk, EOA is good indicator for the success of SAVR than TAVR. TAVR may be preferable to SAVR in patients with better life style modifications.
