Meta Analysis Comparative StudyComparative performance of transcatheter aortic valve-in-valve implantation versus conventional surgical redo aortic valve replacement in patients with degenerated aortic valve bioprostheses: systematic review and meta-analysis.
The objective of this report was to directly compare, by means of a systematic review and meta-analysis, redo surgical aortic valve replacement (re-sAVR) with valve-in-valve transcatheter aortic valve implantation (ViV TAVI) for patients with failed degenerated aortic bioprostheses. Multiple databases were screened for all available reports comparing ViV TAVI with re-sAVR in patients with failing degenerated aortic bioprostheses. The primary outcome was all-cause mortality determined from the longest available survival data. ⋯ In contrast, re-sAVR offered superior echocardiographic outcomes: lower incidence of patient-prosthesis mismatch (P = 0.008), fewer paravalvular leaks (P = 0.023) and lower mean postoperative aortic valve gradients in the prespecified analysis (P = 0.017). The ViV TAVI approach is a safe and feasible alternative to re-sAVR that may offer an effective, less invasive treatment for patients with failed surgical aortic valve bioprostheses who are inoperable or at high risk. Re-sAVR should remain the standard of care, particularly in the low-risk population, because it offers superior haemodynamic outcomes with low mortality rates.
