Redo Surgical Aortic Valve Replacement for Bioprosthetic Structural Valve Deterioration

This study compared isolated primary bioprosthetic surgical aortic valve replacement (SAVR) with isolated redo surgical aortic valve replacement (rSAVR) due to structural valve deterioration (SVD). The study used clinical data from consecutive patients who underwent primary isolated SAVR and isolated rSAVR due to SVD between 1 January 2011 and 31 December 2022. A total of 2,620 patients, with 39.5 percent females, were included, and rSAVR was performed in 174 patients (6.6 percent). In a matched comparison of 322 patients, the rates of death or stroke did not differ between the groups. Therefore, patients undergoing rSAVR on an elective basis can expect outcomes similar to those of primary SAVR.
